OpenShift Container Platform 4.15

Backing up and restoring your OpenShift Container Platform cluster

Red Hat OpenShift Documentation Team

Abstract

This document provides instructions for backing up your cluster's data and for recovering from various disaster scenarios.

Chapter 1. Backup and restore

1.1. Control plane backup and restore operations

As a cluster administrator, you might need to stop an OpenShift Container Platform cluster for a period and restart it later. Some reasons for restarting a cluster are that you need to perform maintenance on a cluster or want to reduce resource costs. In OpenShift Container Platform, you can perform a graceful shutdown of a cluster so that you can easily restart the cluster later.

You must back up etcd data before shutting down a cluster; etcd is the key-value store for OpenShift Container Platform, which persists the state of all resource objects. An etcd backup plays a crucial role in disaster recovery. In OpenShift Container Platform, you can also replace an unhealthy etcd member.

When you want to get your cluster running again, restart the cluster gracefully.

Note

A cluster’s certificates expire one year after the installation date. You can shut down a cluster and expect it to restart gracefully while the certificates are still valid. Although the cluster automatically retrieves the expired control plane certificates, you must still approve the certificate signing requests (CSRs).

You might run into several situations where OpenShift Container Platform does not work as expected, such as:

  • You have a cluster that is not functional after the restart because of unexpected conditions, such as node failure or network connectivity issues.
  • You have deleted something critical in the cluster by mistake.
  • You have lost the majority of your control plane hosts, leading to etcd quorum loss.

You can always recover from a disaster situation by restoring your cluster to its previous state using the saved etcd snapshots.

Additional resources

1.2. Application backup and restore operations

As a cluster administrator, you can back up and restore applications running on OpenShift Container Platform by using the OpenShift API for Data Protection (OADP).

OADP backs up and restores Kubernetes resources and internal images, at the granularity of a namespace, by using the version of Velero that is appropriate for the version of OADP you install, according to the table in Downloading the Velero CLI tool. OADP backs up and restores persistent volumes (PVs) by using snapshots or Restic. For details, see OADP features.

1.2.1. OADP requirements

OADP has the following requirements:

  • You must be logged in as a user with a cluster-admin role.

  • You must have object storage for storing backups, such as one of the following storage types:

    • OpenShift Data Foundation
    • Amazon Web Services
    • Microsoft Azure
    • Google Cloud Platform
    • S3-compatible object storage
    • IBM Cloud® Object Storage S3
Note

If you want to use CSI backup on OCP 4.11 and later, install OADP 1.1.x.

OADP 1.0.x does not support CSI backup on OCP 4.11 and later. OADP 1.0.x includes Velero 1.7.x and expects the API group snapshot.storage.k8s.io/v1beta1, which is not present on OCP 4.11 and later.

Important

The CloudStorage API for S3 storage is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

  • To back up PVs with snapshots, you must have cloud storage that has a native snapshot API or supports Container Storage Interface (CSI) snapshots, such as the following providers:

    • Amazon Web Services
    • Microsoft Azure
    • Google Cloud Platform
    • CSI snapshot-enabled cloud storage, such as Ceph RBD or Ceph FS
Note

If you do not want to back up PVs by using snapshots, you can use Restic, which is installed by the OADP Operator by default.

1.2.2. Backing up and restoring applications

You back up applications by creating a Backup custom resource (CR). See Creating a Backup CR. You can configure the following backup options:

Chapter 2. Shutting down the cluster gracefully

This document describes the process to gracefully shut down your cluster. You might need to temporarily shut down your cluster for maintenance reasons, or to save on resource costs.

2.1. Prerequisites

  • Take an etcd backup prior to shutting down the cluster.

    Important

    It is important to take an etcd backup before performing this procedure so that your cluster can be restored if you encounter any issues when restarting the cluster.

    For example, the following conditions can cause the restarted cluster to malfunction:

    • etcd data corruption during shutdown
    • Node failure due to hardware
    • Network connectivity issues

    If your cluster fails to recover, follow the steps to restore to a previous cluster state.

2.2. Shutting down the cluster

You can shut down your cluster in a graceful manner so that it can be restarted at a later date.

Note

You can shut down a cluster until a year from the installation date and expect it to restart gracefully. After a year from the installation date, the cluster certificates expire.

Prerequisites

  • You have access to the cluster as a user with the cluster-admin role.
  • You have taken an etcd backup.

Procedure

  1. If you are shutting the cluster down for an extended period, determine the date on which certificates expire and run the following command: 

    $ oc -n openshift-kube-apiserver-operator get secret kube-apiserver-to-kubelet-signer -o jsonpath='{.metadata.annotations.auth\.openshift\.io/certificate-not-after}'

    Example output

    2022-08-05T14:37:50Zuser@user:~ $ 1

    1
    To ensure that the cluster can restart gracefully, plan to restart it on or before the specified date. As the cluster restarts, the process might require you to manually approve the pending certificate signing requests (CSRs) to recover kubelet certificates.

  2. Mark all the nodes in the cluster as unschedulable. You can do this from your cloud provider’s web console, or by running the following loop: 

    $ for node in $(oc get nodes -o jsonpath='{.items[*].metadata.name}'); do echo ${node} ; oc adm cordon ${node} ; done

    Example output

    ci-ln-mgdnf4b-72292-n547t-master-0
node/ci-ln-mgdnf4b-72292-n547t-master-0 cordoned
ci-ln-mgdnf4b-72292-n547t-master-1
node/ci-ln-mgdnf4b-72292-n547t-master-1 cordoned
ci-ln-mgdnf4b-72292-n547t-master-2
node/ci-ln-mgdnf4b-72292-n547t-master-2 cordoned
ci-ln-mgdnf4b-72292-n547t-worker-a-s7ntl
node/ci-ln-mgdnf4b-72292-n547t-worker-a-s7ntl cordoned
ci-ln-mgdnf4b-72292-n547t-worker-b-cmc9k
node/ci-ln-mgdnf4b-72292-n547t-worker-b-cmc9k cordoned
ci-ln-mgdnf4b-72292-n547t-worker-c-vcmtn
node/ci-ln-mgdnf4b-72292-n547t-worker-c-vcmtn cordoned

  3. Evacuate the pods using the following method: 

    $ for node in $(oc get nodes -l node-role.kubernetes.io/worker -o jsonpath='{.items[*].metadata.name}'); do echo ${node} ; oc adm drain ${node} --delete-emptydir-data --ignore-daemonsets=true --timeout=15s --force ; done

  4. Shut down all of the nodes in the cluster. You can do this from the web console for your cloud provider web console, or by running the following loop. Shutting down the nodes by using one of these methods allows pods to terminate gracefully, which reduces the chance for data corruption.

    Note

    Ensure that the control plane node with the API VIP assigned is the last node processed in the loop. Otherwise, the shutdown command fails. 

    $ for node in $(oc get nodes -o jsonpath='{.items[*].metadata.name}'); do oc debug node/${node} -- chroot /host shutdown -h 1; done 1
    1
    -h 1 indicates how long, in minutes, this process lasts before the control plane nodes are shut down. For large-scale clusters with 10 nodes or more, set to -h 10 or longer to make sure all the compute nodes have time to shut down first.

    Example output

    Starting pod/ip-10-0-130-169us-east-2computeinternal-debug ...
To use host binaries, run `chroot /host`
Shutdown scheduled for Mon 2021-09-13 09:36:17 UTC, use 'shutdown -c' to cancel.
Removing debug pod ...
Starting pod/ip-10-0-150-116us-east-2computeinternal-debug ...
To use host binaries, run `chroot /host`
Shutdown scheduled for Mon 2021-09-13 09:36:29 UTC, use 'shutdown -c' to cancel.

    Note

    It is not necessary to drain control plane nodes of the standard pods that ship with OpenShift Container Platform prior to shutdown. Cluster administrators are responsible for ensuring a clean restart of their own workloads after the cluster is restarted. If you drained control plane nodes prior to shutdown because of custom workloads, you must mark the control plane nodes as schedulable before the cluster will be functional again after restart.

  5. Shut off any cluster dependencies that are no longer needed, such as external storage or an LDAP server. Be sure to consult your vendor’s documentation before doing so.

    Important

    If you deployed your cluster on a cloud-provider platform, do not shut down, suspend, or delete the associated cloud resources. If you delete the cloud resources of a suspended virtual machine, OpenShift Container Platform might not restore successfully.

Chapter 3. Restarting the cluster gracefully

This document describes the process to restart your cluster after a graceful shutdown.

Even though the cluster is expected to be functional after the restart, the cluster might not recover due to unexpected conditions, for example:

  • etcd data corruption during shutdown
  • Node failure due to hardware
  • Network connectivity issues

If your cluster fails to recover, follow the steps to restore to a previous cluster state.

3.1. Prerequisites

3.2. Restarting the cluster

You can restart your cluster after it has been shut down gracefully.

Prerequisites

  • You have access to the cluster as a user with the cluster-admin role.
  • This procedure assumes that you gracefully shut down the cluster.

Procedure

  1. Power on any cluster dependencies, such as external storage or an LDAP server.

  2. Start all cluster machines.

    Use the appropriate method for your cloud environment to start the machines, for example, from your cloud provider’s web console.

    Wait approximately 10 minutes before continuing to check the status of control plane nodes.

  3. Verify that all control plane nodes are ready. 

    $ oc get nodes -l node-role.kubernetes.io/master

    The control plane nodes are ready if the status is Ready, as shown in the following output: 

    NAME                           STATUS   ROLES    AGE   VERSION
ip-10-0-168-251.ec2.internal   Ready    master   75m   v1.28.5
ip-10-0-170-223.ec2.internal   Ready    master   75m   v1.28.5
ip-10-0-211-16.ec2.internal    Ready    master   75m   v1.28.5

  4. If the control plane nodes are not ready, then check whether there are any pending certificate signing requests (CSRs) that must be approved.

    1. Get the list of current CSRs: 

      $ oc get csr

    2. Review the details of a CSR to verify that it is valid: 

      $ oc describe csr <csr_name> 1
      1
      <csr_name> is the name of a CSR from the list of current CSRs.

    3. Approve each valid CSR: 

      $ oc adm certificate approve <csr_name>

  5. After the control plane nodes are ready, verify that all worker nodes are ready. 

    $ oc get nodes -l node-role.kubernetes.io/worker

    The worker nodes are ready if the status is Ready, as shown in the following output: 

    NAME                           STATUS   ROLES    AGE   VERSION
ip-10-0-179-95.ec2.internal    Ready    worker   64m   v1.28.5
ip-10-0-182-134.ec2.internal   Ready    worker   64m   v1.28.5
ip-10-0-250-100.ec2.internal   Ready    worker   64m   v1.28.5

  6. If the worker nodes are not ready, then check whether there are any pending certificate signing requests (CSRs) that must be approved.

    1. Get the list of current CSRs: 

      $ oc get csr

    2. Review the details of a CSR to verify that it is valid: 

      $ oc describe csr <csr_name> 1
      1
      <csr_name> is the name of a CSR from the list of current CSRs.

    3. Approve each valid CSR: 

      $ oc adm certificate approve <csr_name>

  7. Verify that the cluster started properly.

    1. Check that there are no degraded cluster Operators. 

      $ oc get clusteroperators

      Check that there are no cluster Operators with the DEGRADED condition set to True. 

      NAME                                       VERSION   AVAILABLE   PROGRESSING   DEGRADED   SINCE
authentication                             4.15.0    True        False         False      59m
cloud-credential                           4.15.0    True        False         False      85m

...

    2. Check that all nodes are in the Ready state: 

      $ oc get nodes

      Check that the status for all nodes is Ready. 

      NAME                           STATUS   ROLES    AGE   VERSION
ip-10-0-168-251.ec2.internal   Ready    master   82m   v1.28.5
ip-10-0-170-223.ec2.internal   Ready    master   82m   v1.28.5
ip-10-0-179-95.ec2.internal    Ready    worker   70m   v1.28.5
ip-10-0-182-134.ec2.internal   Ready    worker   70m   v1.28.5
ip-10-0-211-16.ec2.internal    Ready    master   82m   v1.28.5
ip-10-0-250-100.ec2.internal   Ready    worker   69m   v1.28.5

      If the cluster did not start properly, you might need to restore your cluster using an etcd backup.

  8. After the control plane and worker nodes are ready, mark all the nodes in the cluster as schedulable. Run the following command: 

    for node in $(oc get nodes -o jsonpath='{.items[*].metadata.name}'); do echo ${node} ; oc adm uncordon ${node} ; done

Chapter 4. OADP Application backup and restore

4.1. Introduction to OpenShift API for Data Protection

The OpenShift API for Data Protection (OADP) product safeguards customer applications on OpenShift Container Platform. It offers comprehensive disaster recovery protection, covering OpenShift Container Platform applications, application-related cluster resources, persistent volumes, and internal images. OADP is also capable of backing up both containerized applications and virtual machines (VMs).

However, OADP does not serve as a disaster recovery solution for etcd or OpenShift Operators.

4.1.1. OpenShift API for Data Protection APIs

OpenShift API for Data Protection (OADP) provides APIs that enable multiple approaches to customizing backups and preventing the inclusion of unnecessary or inappropriate resources.

OADP provides the following APIs:

4.2. OADP release notes

4.2.1. OADP 1.4 release notes

The release notes for OpenShift API for Data Protection (OADP) describe new features and enhancements, deprecated features, product recommendations, known issues, and resolved issues.

4.2.1.1. OADP 1.4.1 release notes

The OpenShift API for Data Protection (OADP) 1.4.1 release notes lists new features, resolved issues and bugs, and known issues.

4.2.1.1.1. New features

New DPA fields to update client qps and burst

You can now change Velero Server Kubernetes API queries per second and burst values by using the new Data Protection Application (DPA) fields. The new DPA fields are spec.configuration.velero.client-qps and spec.configuration.velero.client-burst, which both default to 100. OADP-4076

Enabling non-default algorithms with Kopia

With this update, you can now configure the hash, encryption, and splitter algorithms in Kopia to select non-default options to optimize performance for different backup workloads.

To configure these algorithms, set the env variable of a velero pod in the podConfig section of the DataProtectionApplication (DPA) configuration. If this variable is not set, or an unsupported algorithm is chosen, Kopia will default to its standard algorithms. OADP-4640

4.2.1.1.2. Resolved issues

Restoring a backup without pods is now successful

Previously, restoring a backup without pods and having StorageClass VolumeBindingMode set as WaitForFirstConsumer, resulted in the PartiallyFailed status with an error: fail to patch dynamic PV, err: context deadline exceeded. With this update, patching dynamic PV is skipped and restoring a backup is successful without any PartiallyFailed status. OADP-4231

PodVolumeBackup CR now displays correct message

Previously, the PodVolumeBackup custom resource (CR) generated an incorrect message, which was: get a podvolumebackup with status "InProgress" during the server starting, mark it as "Failed". With this update, the message produced is now: 

found a podvolumebackup with status "InProgress" during the server starting,
mark it as "Failed".

OADP-4224

Overriding imagePullPolicy is now possible with DPA

Previously, OADP set the imagePullPolicy parameter to Always for all images. With this update, OADP checks if each image contains sha256 or sha512 digest, then it sets imagePullPolicy to IfNotPresent; otherwise imagePullPolicy is set to Always. You can now override this policy by using the new spec.containerImagePullPolicy DPA field. OADP-4172

OADP Velero can now retry updating the restore status if initial update fails

Previously, OADP Velero failed to update the restored CR status. This left the status at InProgress indefinitely. Components which relied on the backup and restore CR status to determine the completion would fail. With this update, the restore CR status for a restore correctly proceeds to the Completed or Failed status. OADP-3227

Restoring BuildConfig Build from a different cluster is successful without any errors

Previously, when performing a restore of the BuildConfig Build resource from a different cluster, the application generated an error on TLS verification to the internal image registry. The resulting error was failed to verify certificate: x509: certificate signed by unknown authority error. With this update, the restore of the BuildConfig build resources to a different cluster can proceed successfully without generating the failed to verify certificate error. OADP-4692

Restoring an empty PVC is successful

Previously, downloading data failed while restoring an empty persistent volume claim (PVC). It failed with the following error: 

data path restore failed: Failed to run kopia restore: Unable to load
    snapshot : snapshot not found

With this update, the downloading of data proceeds to correct conclusion when restoring an empty PVC and the error message is not generated. OADP-3106

There is no Velero memory leak in CSI and DataMover plugins

Previously, a Velero memory leak was caused by using the CSI and DataMover plugins. When the backup ended, the Velero plugin instance was not deleted and the memory leak consumed memory until an Out of Memory (OOM) condition was generated in the Velero pod. With this update, there is no resulting Velero memory leak when using the CSI and DataMover plugins. OADP-4448

Post-hook operation does not start before the related PVs are released

Previously, due to the asynchronous nature of the Data Mover operation, a post-hook might be attempted before the Data Mover persistent volume claim (PVC) releases the persistent volumes (PVs) of the related pods. This problem would cause the backup to fail with a PartiallyFailed status. With this update, the post-hook operation is not started until the related PVs are released by the Data Mover PVC, eliminating the PartiallyFailed backup status. OADP-3140

Deploying a DPA works as expected in namespaces with more than 37 characters

When you install the OADP Operator in a namespace with more than 37 characters to create a new DPA, labeling the "cloud-credentials" Secret fails and the DPA reports the following error: 

The generated label name is too long.

With this update, creating a DPA does not fail in namespaces with more than 37 characters in the name. OADP-3960

Restore is successfully completed by overriding the timeout error

Previously, in a large scale environment, the restore operation would result in a Partiallyfailed status with the error: fail to patch dynamic PV, err: context deadline exceeded. With this update, the resourceTimeout Velero server argument is used to override this timeout error resulting in a successful restore. OADP-4344

For a complete list of all issues resolved in this release, see the list of OADP 1.4.1 resolved issues in Jira.

4.2.1.1.3. Known issues

Cassandra application pods enter into the CrashLoopBackoff status after restoring OADP

After OADP restores, the Cassandra application pods might enter CrashLoopBackoff status. To work around this problem, delete the StatefulSet pods that are returning the error CrashLoopBackoff state after restoring OADP. The StatefulSet controller then recreates these pods and it runs normally. OADP-4407

Deployment referencing ImageStream is not restored properly leading to corrupted pod and volume contents

During a File System Backup (FSB) restore operation, a Deployment resource referencing an ImageStream is not restored properly. The restored pod that runs the FSB, and the postHook is terminated prematurely.

During the restore operation, the OpenShift Container Platform controller updates the spec.template.spec.containers[0].image field in the Deployment resource with an updated ImageStreamTag hash. The update triggers the rollout of a new pod, terminating the pod on which velero runs the FSB along with the post-hook. For more information about image stream trigger, see Triggering updates on image stream changes.

The workaround for this behavior is a two-step restore process:

  1. Perform a restore excluding the Deployment resources, for example: 

    $ velero restore create <RESTORE_NAME> \
  --from-backup <BACKUP_NAME> \
  --exclude-resources=deployment.apps

  2. Once the first restore is successful, perform a second restore by including these resources, for example: 

    $ velero restore create <RESTORE_NAME> \
  --from-backup <BACKUP_NAME> \
  --include-resources=deployment.apps

    OADP-3954

4.2.1.2. OADP 1.4.0 release notes

The OpenShift API for Data Protection (OADP) 1.4.0 release notes lists resolved issues and known issues.

4.2.1.2.1. Resolved issues

Restore works correctly in OpenShift Container Platform 4.16

Previously, while restoring the deleted application namespace, the restore operation partially failed with the resource name may not be empty error in OpenShift Container Platform 4.16. With this update, restore works as expected in OpenShift Container Platform 4.16. OADP-4075

Data Mover backups work properly in the OpenShift Container Platform 4.16 cluster

Previously, Velero was using the earlier version of SDK where the Spec.SourceVolumeMode field did not exist. As a consequence, Data Mover backups failed in the OpenShift Container Platform 4.16 cluster on the external snapshotter with version 4.2. With this update, external snapshotter is upgraded to version 7.0 and later. As a result, backups do not fail in the OpenShift Container Platform 4.16 cluster. OADP-3922

For a complete list of all issues resolved in this release, see the list of OADP 1.4.0 resolved issues in Jira.

4.2.1.2.2. Known issues

Backup fails when checksumAlgorithm is not set for MCG

While performing a backup of any application with Noobaa as the backup location, if the checksumAlgorithm configuration parameter is not set, backup fails. To fix this problem, if you do not provide a value for checksumAlgorithm in the Backup Storage Location (BSL) configuration, an empty value is added. The empty value is only added for BSLs that are created using Data Protection Application (DPA) custom resource (CR), and this value is not added if BSLs are created using any other method. OADP-4274

For a complete list of all known issues in this release, see the list of OADP 1.4.0 known issues in Jira.

4.2.1.2.3. Upgrade notes
Note

Always upgrade to the next minor version. Do not skip versions. To update to a later version, upgrade only one channel at a time. For example, to upgrade from OpenShift API for Data Protection (OADP) 1.1 to 1.3, upgrade first to 1.2, and then to 1.3.

4.2.1.2.3.1. Changes from OADP 1.3 to 1.4

The Velero server has been updated from version 1.12 to 1.14. Note that there are no changes in the Data Protection Application (DPA).

This changes the following:

  • The velero-plugin-for-csi code is now available in the Velero code, which means an init container is no longer required for the plugin.
  • Velero changed client Burst and QPS defaults from 30 and 20 to 100 and 100, respectively.

  • The velero-plugin-for-aws plugin updated default value of the spec.config.checksumAlgorithm field in BackupStorageLocation objects (BSLs) from "" (no checksum calculation) to the CRC32 algorithm. For more information, see Velero plugins for AWS Backup Storage Location. The checksum algorithm types are known to work only with AWS. Several S3 providers require the md5sum to be disabled by setting the checksum algorithm to "". Confirm md5sum algorithm support and configuration with your storage provider.

    In OADP 1.4, the default value for BSLs created within DPA for this configuration is "". This default value means that the md5sum is not checked, which is consistent with OADP 1.3. For BSLs created within DPA, update it by using the spec.backupLocations[].velero.config.checksumAlgorithm field in the DPA. If your BSLs are created outside DPA, you can update this configuration by using spec.config.checksumAlgorithm in the BSLs.

4.2.1.2.3.2. Backing up the DPA configuration

You must back up your current DataProtectionApplication (DPA) configuration.

Procedure

  • Save your current DPA configuration by running the following command:

    Example command

    $ oc get dpa -n openshift-adp -o yaml > dpa.orig.backup

4.2.1.2.3.3. Upgrading the OADP Operator

Use the following procedure when upgrading the OpenShift API for Data Protection (OADP) Operator.

Procedure

  1. Change your subscription channel for the OADP Operator from stable-1.3 to stable-1.4.
  2. Wait for the Operator and containers to update and restart.

Additional resources

4.2.1.2.4. Converting DPA to the new version

To upgrade from OADP 1.3 to 1.4, no Data Protection Application (DPA) changes are required.

4.2.1.2.5. Verifying the upgrade

Verify the installation by following steps from the Verifying the upgrade section.

4.2.2. OADP 1.3 release notes

The release notes for OpenShift API for Data Protection (OADP) 1.3 describe new features and enhancements, deprecated features, product recommendations, known issues, and resolved issues.

4.2.2.1. OADP 1.3.3 release notes

The OpenShift API for Data Protection (OADP) 1.3.3 release notes list resolved issues and known issues.

4.2.2.1.1. Resolved issues

OADP fails when its namespace name is longer than 37 characters

When installing the OADP Operator in a namespace with more than 37 characters and when creating a new DPA, labeling the cloud-credentials secret fails. With this release, the issue has been fixed. OADP-4211

OADP image PullPolicy set to Always

In previous versions of OADP, the image PullPolicy of the adp-controller-manager and Velero pods was set to Always. This was problematic in edge scenarios where there could be limited network bandwidth to the registry, resulting in slow recovery time following a pod restart. In OADP 1.3.3, the image PullPolicy of the openshift-adp-controller-manager and Velero pods is set to IfNotPresent.

The list of security fixes that are included in this release is documented in the RHSA-2024:4982 advisory.

For a complete list of all issues resolved in this release, see the list of OADP 1.3.3 resolved issues in Jira.

4.2.2.1.2. Known issues

Cassandra application pods enter into the CrashLoopBackoff status after restoring OADP

After OADP restores, the Cassandra application pods might enter in the CrashLoopBackoff status. To work around this problem, delete the StatefulSet pods that are returning an error or the CrashLoopBackoff state after restoring OADP. The StatefulSet controller recreates these pods and it runs normally.

OADP-3767

4.2.2.2. OADP 1.3.2 release notes

The OpenShift API for Data Protection (OADP) 1.3.2 release notes list resolved issues and known issues.

4.2.2.2.1. Resolved issues

DPA fails to reconcile if a valid custom secret is used for BSL

DPA fails to reconcile if a valid custom secret is used for Backup Storage Location (BSL), but the default secret is missing. The workaround is to create the required default cloud-credentials initially. When the custom secret is re-created, it can be used and checked for its existence.

OADP-3193

CVE-2023-45290: oadp-velero-container: Golang net/http: Memory exhaustion in Request.ParseMultipartForm

A flaw was found in the net/http Golang standard library package, which impacts previous versions of OADP. When parsing a multipart form, either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile, limits on the total size of the parsed form are not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing long lines to cause the allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. This flaw has been resolved in OADP 1.3.2.

For more details, see CVE-2023-45290.

CVE-2023-45289: oadp-velero-container: Golang net/http/cookiejar: Incorrect forwarding of sensitive headers and cookies on HTTP redirect

A flaw was found in the net/http/cookiejar Golang standard library package, which impacts previous versions of OADP. When following an HTTP redirect to a domain that is not a subdomain match or exact match of the initial domain, an http.Client does not forward sensitive headers such as Authorization or Cookie. A maliciously crafted HTTP redirect could cause sensitive headers to be unexpectedly forwarded. This flaw has been resolved in OADP 1.3.2.

For more details, see CVE-2023-45289.

CVE-2024-24783: oadp-velero-container: Golang crypto/x509: Verify panics on certificates with an unknown public key algorithm

A flaw was found in the crypto/x509 Golang standard library package, which impacts previous versions of OADP. Verifying a certificate chain that contains a certificate with an unknown public key algorithm causes Certificate.Verify to panic. This affects all crypto/tls clients and servers that set Config.ClientAuth to VerifyClientCertIfGiven or RequireAndVerifyClientCert. The default behavior is for TLS servers to not verify client certificates. This flaw has been resolved in OADP 1.3.2.

For more details, see CVE-2024-24783.

CVE-2024-24784: oadp-velero-plugin-container: Golang net/mail: Comments in display names are incorrectly handled

A flaw was found in the net/mail Golang standard library package, which impacts previous versions of OADP. The ParseAddressList function incorrectly handles comments, text in parentheses, and display names. Because this is a misalignment with conforming address parsers, it can result in different trust decisions being made by programs using different parsers. This flaw has been resolved in OADP 1.3.2.

For more details, see CVE-2024-24784.

CVE-2024-24785: oadp-velero-container: Golang: html/template: errors returned from MarshalJSON methods may break template escaping

A flaw was found in the html/template Golang standard library package, which impacts previous versions of OADP. If errors returned from MarshalJSON methods contain user-controlled data, they may be used to break the contextual auto-escaping behavior of the HTML/template package, allowing subsequent actions to inject unexpected content into the templates. This flaw has been resolved in OADP 1.3.2.

For more details, see CVE-2024-24785.

For a complete list of all issues resolved in this release, see the list of OADP 1.3.2 resolved issues in Jira.

4.2.2.2.2. Known issues

Cassandra application pods enter into the CrashLoopBackoff status after restoring OADP

After OADP restores, the Cassandra application pods might enter in the CrashLoopBackoff status. To work around this problem, delete the StatefulSet pods that are returning an error or the CrashLoopBackoff state after restoring OADP. The StatefulSet controller recreates these pods and it runs normally.

OADP-3767

4.2.2.3. OADP 1.3.1 release notes

The OpenShift API for Data Protection (OADP) 1.3.1 release notes lists new features and resolved issues.

4.2.2.3.1. New features

OADP 1.3.0 Data Mover is now fully supported

The OADP built-in Data Mover, introduced in OADP 1.3.0 as a Technology Preview, is now fully supported for both containerized and virtual machine workloads.

4.2.2.3.2. Resolved issues

IBM Cloud(R) Object Storage is now supported as a backup storage provider

IBM Cloud® Object Storage is one of the AWS S3 compatible backup storage providers, which was unsupported previously. With this update, IBM Cloud® Object Storage is now supported as an AWS S3 compatible backup storage provider.

OADP-3788

OADP operator now correctly reports the missing region error

Previously, when you specified profile:default without specifying the region in the AWS Backup Storage Location (BSL) configuration, the OADP operator failed to report the missing region error on the Data Protection Application (DPA) custom resource (CR). This update corrects validation of DPA BSL specification for AWS. As a result, the OADP Operator reports the missing region error.

OADP-3044

Custom labels are not removed from the openshift-adp namespace

Previously, the openshift-adp-controller-manager pod would reset the labels attached to the openshift-adp namespace. This caused synchronization issues for applications requiring custom labels such as Argo CD, leading to improper functionality. With this update, this issue is fixed and custom labels are not removed from the openshift-adp namespace.

OADP-3189

OADP must-gather image collects CRDs

Previously, the OADP must-gather image did not collect the custom resource definitions (CRDs) shipped by OADP. Consequently, you could not use the omg tool to extract data in the support shell. With this fix, the must-gather image now collects CRDs shipped by OADP and can use the omg tool to extract data.

Garbage collection has the correct description for the default frequency value

Previously, the garbage-collection-frequency field had a wrong description for the default frequency value. With this update, garbage-collection-frequency has a correct value of one hour for the gc-controller reconciliation default frequency.

OADP-3486

FIPS Mode flag is available in OperatorHub

By setting the fips-compliant flag to true, the FIPS mode flag is now added to the OADP Operator listing in OperatorHub. This feature was enabled in OADP 1.3.0 but did not show up in the Red Hat Container catalog as being FIPS enabled.

OADP-3495

CSI plugin does not panic with a nil pointer when csiSnapshotTimeout is set to a short duration

Previously, when the csiSnapshotTimeout parameter was set to a short duration, the CSI plugin encountered the following error: plugin panicked: runtime error: invalid memory address or nil pointer dereference.

With this fix, the backup fails with the following error: Timed out awaiting reconciliation of volumesnapshot.

For a complete list of all issues resolved in this release, see the list of OADP 1.3.1 resolved issues in Jira.

4.2.2.3.3. Known issues

Backup and storage restrictions for Single-node OpenShift clusters deployed on IBM Power(R) and IBM Z(R) platforms

Review the following backup and storage related restrictions for Single-node OpenShift clusters that are deployed on IBM Power® and IBM Z® platforms:

Storage
Only NFS storage is currently compatible with single-node OpenShift clusters deployed on IBM Power® and IBM Z® platforms.
Backup
Only the backing up applications with File System Backup such as kopia and restic are supported for backup and restore operations.

OADP-3787

Cassandra application pods enter in the CrashLoopBackoff status after restoring OADP

After OADP restores, the Cassandra application pods might enter in the CrashLoopBackoff status. To work around this problem, delete the StatefulSet pods with any error or the CrashLoopBackoff state after restoring OADP. The StatefulSet controller recreates these pods and it runs normally.

OADP-3767

4.2.2.4. OADP 1.3.0 release notes

The OpenShift API for Data Protection (OADP) 1.3.0 release notes lists new features, resolved issues and bugs, and known issues.

4.2.2.4.1. New features
Velero built-in DataMover

Velero built-in DataMover is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

OADP 1.3 includes a built-in Data Mover that you can use to move Container Storage Interface (CSI) volume snapshots to a remote object store. The built-in Data Mover allows you to restore stateful applications from the remote object store if a failure, accidental deletion, or corruption of the cluster occurs. It uses Kopia as the uploader mechanism to read the snapshot data and to write to the Unified Repository.

Backing up applications with File System Backup: Kopia or Restic

Velero’s File System Backup (FSB) supports two backup libraries: the Restic path and the Kopia path.

Velero allows users to select between the two paths.

For backup, specify the path during the installation through the uploader-type flag. The valid value is either restic or kopia. This field defaults to kopia if the value is not specified. The selection cannot be changed after the installation.

GCP Cloud authentication

Google Cloud Platform (GCP) authentication enables you to use short-lived Google credentials.

GCP with Workload Identity Federation enables you to use Identity and Access Management (IAM) to grant external identities IAM roles, including the ability to impersonate service accounts. This eliminates the maintenance and security risks associated with service account keys.

AWS ROSA STS authentication

You can use OpenShift API for Data Protection (OADP) with Red Hat OpenShift Service on AWS (ROSA) clusters to backup and restore application data.

ROSA provides seamless integration with a wide range of AWS compute, database, analytics, machine learning, networking, mobile, and other services to speed up the building and delivering of differentiating experiences to your customers.

You can subscribe to the service directly from your AWS account.

After the clusters are created, you can operate your clusters by using the OpenShift web console. The ROSA service also uses OpenShift APIs and command-line interface (CLI) tools.

4.2.2.4.2. Resolved issues

ACM applications were removed and re-created on managed clusters after restore

Applications on managed clusters were deleted and re-created upon restore activation. OpenShift API for Data Protection (OADP 1.2) backup and restore process is faster than the older versions. The OADP performance change caused this behavior when restoring ACM resources. Therefore, some resources were restored before other resources, which caused the removal of the applications from managed clusters. OADP-2686

Restic restore was partially failing due to Pod Security standard

During interoperability testing, OpenShift Container Platform 4.14 had the pod Security mode set to enforce, which caused the pod to be denied. This was caused due to the restore order. The pod was getting created before the security context constraints (SCC) resource, since the pod violated the podSecurity standard, it denied the pod. When setting the restore priority field on the Velero server, restore is successful. OADP-2688

Possible pod volume backup failure if Velero is installed in several namespaces

There was a regression in Pod Volume Backup (PVB) functionality when Velero was installed in several namespaces. The PVB controller was not properly limiting itself to PVBs in its own namespace. OADP-2308

OADP Velero plugins returning "received EOF, stopping recv loop" message

In OADP, Velero plugins were started as separate processes. When the Velero operation completes, either successfully or not, they exit. Therefore, if you see a received EOF, stopping recv loop messages in debug logs, it does not mean an error occurred, it means that a plugin operation has completed. OADP-2176

CVE-2023-39325 Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

In previous releases of OADP, the HTTP/2 protocol was susceptible to a denial of service attack because request cancellation could reset multiple streams quickly. The server had to set up and tear down the streams while not hitting any server-side limit for the maximum number of active streams per connection. This resulted in a denial of service due to server resource consumption.

For more information, see CVE-2023-39325 (Rapid Reset Attack)

For a complete list of all issues resolved in this release, see the list of OADP 1.3.0 resolved issues in Jira.

4.2.2.4.3. Known issues

CSI plugin errors on nil pointer when csiSnapshotTimeout is set to a short duration

The CSI plugin errors on nil pointer when csiSnapshotTimeout is set to a short duration. Sometimes it succeeds to complete the snapshot within a short duration, but often it panics with the backup PartiallyFailed with the following error: plugin panicked: runtime error: invalid memory address or nil pointer dereference.

Backup is marked as PartiallyFailed when volumeSnapshotContent CR has an error

If any of the VolumeSnapshotContent CRs have an error related to removing the VolumeSnapshotBeingCreated annotation, it moves the backup to the WaitingForPluginOperationsPartiallyFailed phase. OADP-2871

Performance issues when restoring 30,000 resources for the first time

When restoring 30,000 resources for the first time, without an existing-resource-policy, it takes twice as long to restore them, than it takes during the second and third try with an existing-resource-policy set to update. OADP-3071

Post restore hooks might start running before Datadownload operation has released the related PV

Due to the asynchronous nature of the Data Mover operation, a post-hook might be attempted before the related pods persistent volumes (PVs) are released by the Data Mover persistent volume claim (PVC).

GCP-Workload Identity Federation VSL backup PartiallyFailed

VSL backup PartiallyFailed when GCP workload identity is configured on GCP.

For a complete list of all known issues in this release, see the list of OADP 1.3.0 known issues in Jira.

4.2.2.4.4. Upgrade notes
Note

Always upgrade to the next minor version. Do not skip versions. To update to a later version, upgrade only one channel at a time. For example, to upgrade from OpenShift API for Data Protection (OADP) 1.1 to 1.3, upgrade first to 1.2, and then to 1.3.

4.2.2.4.4.1. Changes from OADP 1.2 to 1.3

The Velero server has been updated from version 1.11 to 1.12.

OpenShift API for Data Protection (OADP) 1.3 uses the Velero built-in Data Mover instead of the VolumeSnapshotMover (VSM) or the Volsync Data Mover.

This changes the following:

  • The spec.features.dataMover field and the VSM plugin are not compatible with OADP 1.3, and you must remove the configuration from the DataProtectionApplication (DPA) configuration.
  • The Volsync Operator is no longer required for Data Mover functionality, and you can remove it.
  • The custom resource definitions volumesnapshotbackups.datamover.oadp.openshift.io and volumesnapshotrestores.datamover.oadp.openshift.io are no longer required, and you can remove them.
  • The secrets used for the OADP-1.2 Data Mover are no longer required, and you can remove them.

OADP 1.3 supports Kopia, which is an alternative file system backup tool to Restic.

  • To employ Kopia, use the new spec.configuration.nodeAgent field as shown in the following example:

    Example

    spec:
  configuration:
    nodeAgent:
      enable: true
      uploaderType: kopia
# ...

  • The spec.configuration.restic field is deprecated in OADP 1.3 and will be removed in a future version of OADP. To avoid seeing deprecation warnings, remove the restic key and its values, and use the following new syntax:

    Example

    spec:
  configuration:
    nodeAgent:
      enable: true
      uploaderType: restic
# ...

Note

In a future OADP release, it is planned that the kopia tool will become the default uploaderType value.

4.2.2.4.4.2. Upgrading from OADP 1.2 Technology Preview Data Mover

OpenShift API for Data Protection (OADP) 1.2 Data Mover backups cannot be restored with OADP 1.3. To prevent a gap in the data protection of your applications, complete the following steps before upgrading to OADP 1.3:

Procedure

  1. If your cluster backups are sufficient and Container Storage Interface (CSI) storage is available, back up the applications with a CSI backup.

  2. If you require off cluster backups:

    1. Back up the applications with a file system backup that uses the --default-volumes-to-fs-backup=true or backup.spec.defaultVolumesToFsBackup options.
    2. Back up the applications with your object storage plugins, for example, velero-plugin-for-aws.
Note

The default timeout value for the Restic file system backup is one hour. In OADP 1.3.1 and later, the default timeout value for Restic and Kopia is four hours.

Important

To restore OADP 1.2 Data Mover backup, you must uninstall OADP, and install and configure OADP 1.2.

4.2.2.4.4.3. Backing up the DPA configuration

You must back up your current DataProtectionApplication (DPA) configuration.

Procedure

  • Save your current DPA configuration by running the following command:

    Example

    $ oc get dpa -n openshift-adp -o yaml > dpa.orig.backup

4.2.2.4.4.4. Upgrading the OADP Operator

Use the following sequence when upgrading the OpenShift API for Data Protection (OADP) Operator.

Procedure

  1. Change your subscription channel for the OADP Operator from stable-1.2 to stable-1.3.
  2. Allow time for the Operator and containers to update and restart.

Additional resources

4.2.2.4.4.5. Converting DPA to the new version

If you need to move backups off cluster with the Data Mover, reconfigure the DataProtectionApplication (DPA) manifest as follows.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. In the Provided APIs section, click View more.
  3. Click Create instance in the DataProtectionApplication box.

  4. Click YAML View to display the current DPA parameters.

    Example current DPA

    spec:
  configuration:
    features:
      dataMover:
      enable: true
      credentialName: dm-credentials
    velero:
      defaultPlugins:
      - vsm
      - csi
      - openshift
# ...

  5. Update the DPA parameters:

    • Remove the features.dataMover key and values from the DPA.
    • Remove the VolumeSnapshotMover (VSM) plugin.

    • Add the nodeAgent key and values.

      Example updated DPA

      spec:
  configuration:
    nodeAgent:
      enable: true
      uploaderType: kopia
    velero:
      defaultPlugins:
      - csi
      - openshift
# ...

  6. Wait for the DPA to reconcile successfully.
4.2.2.4.4.6. Verifying the upgrade

Use the following procedure to verify the upgrade.

Procedure

  1. Verify the installation by viewing the OpenShift API for Data Protection (OADP) resources by running the following command: 

    $ oc get all -n openshift-adp

    Example output

  2. Verify that the DataProtectionApplication (DPA) is reconciled by running the following command: 

    $ oc get dpa dpa-sample -n openshift-adp -o jsonpath='{.status}'

    Example output

    {"conditions":[{"lastTransitionTime":"2023-10-27T01:23:57Z","message":"Reconcile complete","reason":"Complete","status":"True","type":"Reconciled"}]}

  3. Verify the type is set to Reconciled.

  4. Verify the backup storage location and confirm that the PHASE is Available by running the following command: 

    $ oc get backupStorageLocation -n openshift-adp

    Example output

    NAME           PHASE       LAST VALIDATED   AGE     DEFAULT
dpa-sample-1   Available   1s               3d16h   true

In OADP 1.3 you can start data movement off cluster per backup versus creating a DataProtectionApplication (DPA) configuration.

Example

$ velero backup create example-backup --include-namespaces mysql-persistent --snapshot-move-data=true

Example

apiVersion: velero.io/v1
kind: Backup

4.2.3. OADP 1.2 release notes

The release notes for OpenShift API for Data Protection (OADP) 1.2 describe new features and enhancements, deprecated features, product recommendations, known issues, and resolved issues.

4.2.3.1. OADP 1.2.5 release notes

OpenShift API for Data Protection (OADP) 1.2.5 is a Container Grade Only (CGO) release, released to refresh the health grades of the containers, with no changes to any code in the product itself compared to that of OADP 1.2.4.

4.2.3.1.1. Resolved issues

CVE-2023-2431: oadp-velero-plugin-for-microsoft-azure-container: Bypass of seccomp profile enforcement

A flaw was found in Kubernetes, which impacts earlier versions of OADP. This flaw arises when Kubernetes allows a local authenticated attacker to bypass security restrictions, caused by a flaw when using the localhost type for a seccomp profile but specifying an empty profile field. An attacker can bypass the seccomp profile enforcement by sending a specially crafted request. This flaw has been resolved in OADP 1.2.5.

For more details, see (CVE-2023-2431).

CSI restore ended with 'PartiallyFailed' status and PVCs not created

CSI restore ended with PartiallyFailed status. PVCs are not created, pod are in Pending status. This issue has been resolved in OADP 1.2.5.

(OADP-1956)

PodVolumeBackup fails on completed pod volumes

In earlier versions of OADP 1.2, when there is a completed pod that mounted volumes in a namespace used by the Restic podvolumebackup or Velero backup, the backup does not complete successfully. This occurs when defaultVolumesToFsBackup is set to true. This issue has been resolved in OADP 1.2.5.

(OADP-1870)

4.2.3.1.2. Known issues

Data Protection Application (DPA) does not reconcile when the credentials secret is updated

Currently, the OADP Operator does not reconcile when you update the cloud-credentials secret. This occurs because there are no OADP specific labels or owner references on the cloud-credentials secret. If you create a cloud-credentials secret with incorrect credentials, such as empty data, the Operator reconciles and creates a backup storage location (BSL) and registry deployment with the empty data. As a result, when you update the cloud-credentials secret with the correct credentials, the OADP Operator does not immediately reconcile to catch the new credentials.

Workaround: Update to OADP 1.3.

(OADP-3327)

4.2.3.2. OADP 1.2.4 release notes

OpenShift API for Data Protection (OADP) 1.2.4 is a Container Grade Only (CGO) release, released to refresh the health grades of the containers, with no changes to any code in the product itself compared to that of OADP 1.2.3.

4.2.3.2.1. Resolved issues

There are no resolved issues in OADP 1.2.4.

4.2.3.2.2. Known issues

The OADP 1.2.4 has the following known issue:

Data Protection Application (DPA) does not reconcile when the credentials secret is updated

Currently, the OADP Operator does not reconcile when you update the cloud-credentials secret. This occurs because there are no OADP specific labels or owner references on the cloud-credentials secret. If you create a cloud-credentials secret with incorrect credentials, such as empty data, the Operator reconciles and creates a Backup Storage Location (BSL) and registry deployment with the empty data. As a result, when you update the cloud-credentials secret with the correct credentials, the Operator does not immediately reconcile to catch the new credentials.

Workaround: Update to OADP 1.3.

(OADP-3327)

4.2.3.3. OADP 1.2.3 release notes
4.2.3.3.1. New features

There are no new features in the release of OpenShift API for Data Protection (OADP) 1.2.3.

4.2.3.3.2. Resolved issues

The following highlighted issues are resolved in OADP 1.2.3:

Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

In previous releases of OADP 1.2, the HTTP/2 protocol was susceptible to a denial of service attack because request cancellation could reset multiple streams quickly. The server had to set up and tear down the streams while not hitting any server-side limit for the maximum number of active streams per connection. This resulted in a denial of service due to server resource consumption. For a list of all OADP issues associated with this CVE, see the following Jira list.

For more information, see CVE-2023-39325 (Rapid Reset Attack).

For a complete list of all issues resolved in the release of OADP 1.2.3, see the list of OADP 1.2.3 resolved issues in Jira.

4.2.3.3.3. Known issues

The OADP 1.2.3 has the following known issue:

Data Protection Application (DPA) does not reconcile when the credentials secret is updated

Currently, the OADP Operator does not reconcile when you update the cloud-credentials secret. This occurs because there are no OADP specific labels or owner references on the cloud-credentials secret. If you create a cloud-credentials secret with incorrect credentials, such as empty data, the Operator reconciles and creates a Backup Storage Location (BSL) and registry deployment with the empty data. As a result, when you update the cloud-credentials secret with the correct credentials, the Operator does not immediately reconcile to catch the new credentials.

Workaround: Update to OADP 1.3.

4.2.3.4. OADP 1.2.2 release notes
4.2.3.4.1. New features

There are no new features in the release of OpenShift API for Data Protection (OADP) 1.2.2.

4.2.3.4.2. Resolved issues

The following highlighted issues are resolved in OADP 1.2.2:

Restic restore partially failed due to a Pod Security standard

In previous releases of OADP 1.2, OpenShift Container Platform 4.14 enforced a pod security admission (PSA) policy that hindered the readiness of pods during a Restic restore process.

This issue has been resolved in the release of OADP 1.2.2, and also OADP 1.1.6. Therefore, it is recommended that users upgrade to these releases.

For more information, see Restic restore partially failing on OCP 4.14 due to changed PSA policy. (OADP-2094)

Backup of an app with internal images partially failed with plugin panicked error

In previous releases of OADP 1.2, the backup of an application with internal images partially failed with plugin panicked error returned. The backup partially fails with this error in the Velero logs: 

time="2022-11-23T15:40:46Z" level=info msg="1 errors encountered backup up item" backup=openshift-adp/django-persistent-67a5b83d-6b44-11ed-9cba-902e163f806c logSource="/remote-source/velero/app/pkg/backup/backup.go:413" name=django-psql-persistent

This issue has been resolved in OADP 1.2.2. (OADP-1057).

ACM cluster restore was not functioning as expected due to restore order

In previous releases of OADP 1.2, ACM cluster restore was not functioning as expected due to restore order. ACM applications were removed and re-created on managed clusters after restore activation. (OADP-2505)

VM’s using filesystemOverhead failed when backing up and restoring due to volume size mismatch

In previous releases of OADP 1.2, due to storage provider implementation choices, whenever there was a difference between the application persistent volume claims (PVCs) storage request and the snapshot size of the same PVC, VM’s using filesystemOverhead failed when backing up and restoring. This issue has been resolved in the Data Mover of OADP 1.2.2. (OADP-2144)

OADP did not contain an option to set VolSync replication source prune interval

In previous releases of OADP 1.2, there was no option to set the VolSync replication source pruneInterval. (OADP-2052)

Possible pod volume backup failure if Velero was installed in multiple namespaces

In previous releases of OADP 1.2, there was a possibility of pod volume backup failure if Velero was installed in multiple namespaces. (OADP-2409)

Backup Storage Locations moved to unavailable phase when VSL uses custom secret

In previous releases of OADP 1.2, Backup Storage Locations moved to unavailable phase when Volume Snapshot Location used custom secret. (OADP-1737)

4.2.3.4.3. Known issues

The following issues have been highlighted as known issues in the release of OADP 1.2.2:

Must-gather command fails to remove ClusterRoleBinding resources

The oc adm must-gather command fails to remove ClusterRoleBinding resources, which are left on cluster due to admission webhook. Therefore, requests for the removal of the ClusterRoleBinding resources are denied. (OADP-27730) 

admission webhook "clusterrolebindings-validation.managed.openshift.io" denied the request: Deleting ClusterRoleBinding must-gather-p7vwj is not allowed

4.2.3.6.3. Known issues

The following issues have been highlighted as known issues in the release of OADP 1.2.0:

Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

The HTTP/2 protocol is susceptible to a denial of service attack because request cancellation can reset multiple streams quickly. The server has to set up and tear down the streams while not hitting any server-side limit for the maximum number of active streams per connection. This results in a denial of service due to server resource consumption.

It is advised to upgrade to OADP 1.2.3, which resolves this issue.

For more information, see CVE-2023-39325 (Rapid Reset Attack).

An incorrect hostname can be created when changing a hostname in a generated route.

By default, the OpenShift Container Platform cluster makes sure that the openshift.io/host.generated: true annotation is turned on and fills in the field for both the routes that are generated and those that are not generated.

You cannot modify the value for the .spec.host field based on the base domain name of your cluster in the generated and non-generated routes.

If you modify the value for the .spec.host field, it is not possible to restore the default value that was generated by the OpenShift Container Platform cluster. After you restore your OpenShift Container Platform cluster, the Operator resets the value for the field.

4.2.3.6.4. Upgrade notes
Note

Always upgrade to the next minor version. Do not skip versions. To update to a later version, upgrade only one channel at a time. For example, to upgrade from OpenShift API for Data Protection (OADP) 1.1 to 1.3, upgrade first to 1.2, then to 1.3.

4.2.3.6.4.1. Changes from OADP 1.1 to 1.2

The Velero server was updated from version 1.9 to 1.11.

In OADP 1.2, the DataProtectionApplication (DPA) configuration dpa.spec.configuration.velero.args has the following changes:

  • The default-volumes-to-restic field was renamed to default-volumes-to-fs-backup. If you use dpa.spec.configuration.velero.args, you must add it again with the new name to your DPA after upgrading OADP.
  • The restic-timeout field was renamed to fs-backup-timeout. If you use dpa.spec.configuration.velero.args, you must add it again with the new name to your DPA after upgrading OADP.
  • The restic daemon set was renamed to node-agent. OADP automatically updates the name of the daemon set.
  • The custom resource definition resticrepositories.velero.io was renamed to backuprepositories.velero.io.
  • The custom resource definition resticrepositories.velero.io can be removed from the cluster.
4.2.3.6.5. Upgrading steps
4.2.3.6.5.1. Backing up the DPA configuration

You must back up your current DataProtectionApplication (DPA) configuration.

Procedure

  • Save your current DPA configuration by running the following command:

    Example

    $ oc get dpa -n openshift-adp -o yaml > dpa.orig.backup

4.2.3.6.5.2. Upgrading the OADP Operator

Use the following sequence when upgrading the OpenShift API for Data Protection (OADP) Operator.

Procedure

  1. Change your subscription channel for the OADP Operator from stable-1.1 to stable-1.2.
  2. Allow time for the Operator and containers to update and restart.

Additional resources

4.2.3.6.5.3. Converting DPA to the new version

If you use the fields that were updated in the spec.configuration.velero.args stanza, you must configure your DataProtectionApplication (DPA) manifest to use the new parameter names.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Select Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View to display the current DPA parameters.

    Example current DPA

    spec:
  configuration:
    velero:
      args:
        default-volumes-to-fs-backup: true
        default-restic-prune-frequency: 6000
        fs-backup-timeout: 600
# ...

  4. Update the DPA parameters:

  5. Update the DPA parameter names without changing their values:

    1. Change the default-volumes-to-restic key to default-volumes-to-fs-backup.
    2. Change the default-restic-prune-frequency key to default-repo-maintain-frequency.
    3. Change the restic-timeout key to fs-backup-timeout.

    .Example updated DPA 

    spec:
  configuration:
    velero:
      args:
        default-volumes-to-fs-backup: true
        default-repo-maintain-frequency: 6000
        fs-backup-timeout: 600
# ...
  6. Wait for the DPA to reconcile successfully.
Note

The default timeout value for the Restic file system backup is one hour. In OADP 1.3.1 and later, the default timeout value for Restic and Kopia is four hours.

4.2.4.3.1. Resolved issues

Restic restore partially failing due to Pod Security standard

OCP 4.14 introduced pod security standards that meant the privileged profile is enforced. In previous releases of OADP, this profile caused the pod to receive permission denied errors. This issue was caused because of the restore order. The pod was created before the security context constraints (SCC) resource. As this pod violated the pod security standard, the pod was denied and subsequently failed. OADP-2420

Restore partially failing for job resource

In previous releases of OADP, the restore of job resource was partially failing in OCP 4.14. This issue was not seen in older OCP versions. The issue was caused by an additional label being to the job resource, which was not present in older OCP versions. OADP-2530

Add support for all the velero deployment server arguments

In previous releases of OADP, OADP did not facilitate the support of all the upstream Velero server arguments. This issue has been resolved in OADP 1.1.4 and all the upstream Velero server arguments are supported. OADP-1557

Data Mover can restore from an incorrect snapshot when there was more than one VSR for the restore name and pvc name

In previous releases of OADP, OADP Data Mover could restore from an incorrect snapshot if there was more than one Volume Snapshot Restore (VSR) resource in the cluster for the same Velero restore name and PersistentVolumeClaim (pvc) name. OADP-1822

Cloud Storage API BSLs need OwnerReference

In previous releases of OADP, ACM BackupSchedules failed validation because of a missing OwnerReference on Backup Storage Locations (BSLs) created with dpa.spec.backupLocations.bucket. OADP-1511

For a complete list of all issues resolved in this release, see the list of OADP 1.1.4 resolved issues in Jira.

4.2.4.5.3. Known issues

This release has the following known issues:

OADP backups might fail because a UID/GID range might have changed on the cluster

OADP backups might fail because a UID/GID range might have changed on the cluster where the application has been restored, with the result that OADP does not back up and restore OpenShift Container Platform UID/GID range metadata. To avoid the issue, if the backed application requires a specific UUID, ensure the range is available when restored. An additional workaround is to allow OADP to create the namespace in the restore operation.

A restoration might fail if ArgoCD is used during the process due to a label used by ArgoCD

A restoration might fail if ArgoCD is used during the process due to a label used by ArgoCD, app.kubernetes.io/instance. This label identifies which resources ArgoCD needs to manage, which can create a conflict with OADP’s procedure for managing resources on restoration. To work around this issue, set .spec.resourceTrackingMethod on the ArgoCD YAML to annotation+label or annotation. If the issue continues to persist, then disable ArgoCD before beginning to restore, and enable it again when restoration is finished.

OADP Velero plugins returning "received EOF, stopping recv loop" message

Velero plugins are started as separate processes. When the Velero operation has completed, either successfully or not, they exit. Therefore if you see a received EOF, stopping recv loop messages in debug logs, it does not mean an error occurred. The message indicates that a plugin operation has completed. OADP-2176

4.3. OADP features and plugins

OpenShift API for Data Protection (OADP) features provide options for backing up and restoring applications.

The default plugins enable Velero to integrate with certain cloud providers and to back up and restore OpenShift Container Platform resources.

4.3.1. OADP features

OpenShift API for Data Protection (OADP) supports the following features:

Backup

You can use OADP to back up all applications on the OpenShift Platform, or you can filter the resources by type, namespace, or label.

OADP backs up Kubernetes objects and internal images by saving them as an archive file on object storage. OADP backs up persistent volumes (PVs) by creating snapshots with the native cloud snapshot API or with the Container Storage Interface (CSI). For cloud providers that do not support snapshots, OADP backs up resources and PV data with Restic.

Note

You must exclude Operators from the backup of an application for backup and restore to succeed.

Restore

You can restore resources and PVs from a backup. You can restore all objects in a backup or filter the objects by namespace, PV, or label.

Note

You must exclude Operators from the backup of an application for backup and restore to succeed.

Schedule
You can schedule backups at specified intervals.
Hooks
You can use hooks to run commands in a container on a pod, for example, fsfreeze to freeze a file system. You can configure a hook to run before or after a backup or restore. Restore hooks can run in an init container or in the application container.

4.3.2. OADP plugins

The OpenShift API for Data Protection (OADP) provides default Velero plugins that are integrated with storage providers to support backup and snapshot operations. You can create custom plugins based on the Velero plugins.

OADP also provides plugins for OpenShift Container Platform resource backups, OpenShift Virtualization resource backups, and Container Storage Interface (CSI) snapshots.

    • OADP 1.0 uses snapshot.storage.k8s.io/v1beta1
  4. OADP 1.2 only.

4.3.3. About OADP Velero plugins

You can configure two types of plugins when you install Velero:

  • Default cloud provider plugins
  • Custom plugins

Both types of plugin are optional, but most users configure at least one cloud provider plugin.

4.3.3.1. Default Velero cloud provider plugins

You can install any of the following default Velero cloud provider plugins when you configure the oadp_v1alpha1_dpa.yaml file during deployment:

  • aws (Amazon Web Services)
  • gcp (Google Cloud Platform)
  • azure (Microsoft Azure)
  • openshift (OpenShift Velero plugin)
  • csi (Container Storage Interface)
  • kubevirt (KubeVirt)

You specify the desired default plugins in the oadp_v1alpha1_dpa.yaml file during deployment.

Example file

The following .yaml file installs the openshift, aws, azure, and gcp plugins: 

 apiVersion: oadp.openshift.io/v1alpha1
 kind: DataProtectionApplication
 metadata:
   name: dpa-sample
 spec:
   configuration:
     velero:
       defaultPlugins:
       - openshift
       - aws
       - azure
       - gcp
4.3.3.2. Custom Velero plugins

You can install a custom Velero plugin by specifying the plugin image and name when you configure the oadp_v1alpha1_dpa.yaml file during deployment.

You specify the desired custom plugins in the oadp_v1alpha1_dpa.yaml file during deployment.

Example file

The following .yaml file installs the default openshift, azure, and gcp plugins and a custom plugin that has the name custom-plugin-example and the image quay.io/example-repo/custom-velero-plugin: 

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
 name: dpa-sample
spec:
 configuration:
   velero:
     defaultPlugins:
     - openshift
     - azure
     - gcp
     customPlugins:
     - name: custom-plugin-example
       image: quay.io/example-repo/custom-velero-plugin
4.3.3.3. Velero plugins returning "received EOF, stopping recv loop" message
Note

Velero plugins are started as separate processes. After the Velero operation has completed, either successfully or not, they exit. Receiving a received EOF, stopping recv loop message in the debug logs indicates that a plugin operation has completed. It does not mean that an error has occurred.

4.3.4. Supported architectures for OADP

OpenShift API for Data Protection (OADP) supports the following architectures:

  • AMD64
  • ARM64
  • PPC64le
  • s390x

4.3.5.2.1. Known issue of OADP using IBM Power(R) and IBM Z(R) platforms
  • Currently, there are backup method restrictions for Single-node OpenShift clusters deployed on IBM Power® and IBM Z® platforms. Only NFS storage is currently compatible with Single-node OpenShift clusters on these platforms. In addition, only the File System Backup (FSB) methods such as Kopia and Restic are supported for backup and restore operations. There is currently no workaround for this issue.

4.3.6. OADP plugins known issues

The following section describes known issues in OpenShift API for Data Protection (OADP) plugins:

4.3.6.1. Velero plugin panics during imagestream backups due to a missing secret

When the backup and the Backup Storage Location (BSL) are managed outside the scope of the Data Protection Application (DPA), the OADP controller, meaning the DPA reconciliation does not create the relevant oadp-<bsl_name>-<bsl_provider>-registry-secret.

When the backup is run, the OpenShift Velero plugin panics on the imagestream backup, with the following panic error: 

024-02-27T10:46:50.028951744Z time="2024-02-27T10:46:50Z" level=error msg="Error backing up item"
backup=openshift-adp/<backup name> error="error executing custom action (groupResource=imagestreams.image.openshift.io,
namespace=<BSL Name>, name=postgres): rpc error: code = Aborted desc = plugin panicked:
runtime error: index out of range with length 1, stack trace: goroutine 94…
4.3.6.1.1. Workaround to avoid the panic error

To avoid the Velero plugin panic error, perform the following steps:

  1. Label the custom BSL with the relevant label: 

    $ oc label BackupStorageLocation <bsl_name> app.kubernetes.io/component=bsl

  2. After the BSL is labeled, wait until the DPA reconciles.

    Note

    You can force the reconciliation by making any minor change to the DPA itself.

  3. When the DPA reconciles, confirm that the relevant oadp-<bsl_name>-<bsl_provider>-registry-secret has been created and that the correct registry data has been populated into it: 

    $ oc -n openshift-adp get secret/oadp-<bsl_name>-<bsl_provider>-registry-secret -o json | jq -r '.data'
4.3.6.2. OpenShift ADP Controller segmentation fault

If you configure a DPA with both cloudstorage and restic enabled, the openshift-adp-controller-manager pod crashes and restarts indefinitely until the pod fails with a crash loop segmentation fault.

You can have either velero or cloudstorage defined, because they are mutually exclusive fields.

  • If you have both velero and cloudstorage defined, the openshift-adp-controller-manager fails.
  • If you have neither velero nor cloudstorage defined, the openshift-adp-controller-manager fails.

For more information about this issue, see OADP-1054.

4.3.6.2.1. OpenShift ADP Controller segmentation fault workaround

You must define either velero or cloudstorage when you configure a DPA. If you define both APIs in your DPA, the openshift-adp-controller-manager pod fails with a crash loop segmentation fault.

4.4. Installing and configuring OADP

4.4.1. About installing OADP

As a cluster administrator, you install the OpenShift API for Data Protection (OADP) by installing the OADP Operator. The OADP Operator installs Velero 1.14.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

To back up Kubernetes resources and internal images, you must have object storage as a backup location, such as one of the following storage types:

You can configure multiple backup storage locations within the same namespace for each individual OADP deployment.

Note

Unless specified otherwise, "NooBaa" refers to the open source project that provides lightweight object storage, while "Multicloud Object Gateway (MCG)" refers to the Red Hat distribution of NooBaa.

For more information on the MCG, see Accessing the Multicloud Object Gateway with your applications.

Important

The CloudStorage API, which automates the creation of a bucket for object storage, is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

Note

The CloudStorage API is a Technology Preview feature when you use a CloudStorage object and want OADP to use the CloudStorage API to automatically create an S3 bucket for use as a BackupStorageLocation.

The CloudStorage API supports manually creating a BackupStorageLocation object by specifying an existing S3 bucket. The CloudStorage API that creates an S3 bucket automatically is currently only enabled for AWS S3 storage.

You can back up persistent volumes (PVs) by using snapshots or a File System Backup (FSB).

To back up PVs with snapshots, you must have a cloud provider that supports either a native snapshot API or Container Storage Interface (CSI) snapshots, such as one of the following cloud providers:

Note

If you want to use CSI backup on OCP 4.11 and later, install OADP 1.1.x.

OADP 1.0.x does not support CSI backup on OCP 4.11 and later. OADP 1.0.x includes Velero 1.7.x and expects the API group snapshot.storage.k8s.io/v1beta1, which is not present on OCP 4.11 and later.

If your cloud provider does not support snapshots or if your storage is NFS, you can back up applications with Backing up applications with File System Backup: Kopia or Restic on object storage.

You create a default Secret and then you install the Data Protection Application.

4.4.1.1. AWS S3 compatible backup storage providers

OADP is compatible with many object storage providers for use with different backup and snapshot operations. Several object storage providers are fully supported, several are unsupported but known to work, and some have known limitations.

4.4.1.1.1. Supported backup storage providers

The following AWS S3 compatible object storage providers are fully supported by OADP through the AWS plugin for use as backup storage locations:

  • MinIO
  • Multicloud Object Gateway (MCG)
  • Amazon Web Services (AWS) S3
  • IBM Cloud® Object Storage S3
  • Ceph RADOS Gateway (Ceph Object Gateway)
  • Red Hat Container Storage
  • Red Hat OpenShift Data Foundation
Note

The following compatible object storage providers are supported and have their own Velero object store plugins:

  • Google Cloud Platform (GCP)
  • Microsoft Azure
4.4.1.1.2. Unsupported backup storage providers

The following AWS S3 compatible object storage providers, are known to work with Velero through the AWS plugin, for use as backup storage locations, however, they are unsupported and have not been tested by Red Hat:

  • Oracle Cloud
  • DigitalOcean
  • NooBaa, unless installed using Multicloud Object Gateway (MCG)
  • Tencent Cloud
  • Ceph RADOS v12.2.7
  • Quobyte
  • Cloudian HyperStore
Note

Unless specified otherwise, "NooBaa" refers to the open source project that provides lightweight object storage, while "Multicloud Object Gateway (MCG)" refers to the Red Hat distribution of NooBaa.

For more information on the MCG, see Accessing the Multicloud Object Gateway with your applications.

4.4.1.1.3. Backup storage providers with known limitations

The following AWS S3 compatible object storage providers are known to work with Velero through the AWS plugin with a limited feature set:

  • Swift - It works for use as a backup storage location for backup storage, but is not compatible with Restic for filesystem-based volume backup and restore.
4.4.1.2. Configuring Multicloud Object Gateway (MCG) for disaster recovery on OpenShift Data Foundation

If you use cluster storage for your MCG bucket backupStorageLocation on OpenShift Data Foundation, configure MCG as an external object store.

Warning

Failure to configure MCG as an external object store might lead to backups not being available.

Note

Unless specified otherwise, "NooBaa" refers to the open source project that provides lightweight object storage, while "Multicloud Object Gateway (MCG)" refers to the Red Hat distribution of NooBaa.

For more information on the MCG, see Accessing the Multicloud Object Gateway with your applications.

Procedure

Additional resources

4.4.1.3. About OADP update channels

When you install an OADP Operator, you choose an update channel. This channel determines which upgrades to the OADP Operator and to Velero you receive. You can switch channels at any time.

The following update channels are available:

  • The stable channel is now deprecated. The stable channel contains the patches (z-stream updates) of OADP ClusterServiceVersion for OADP.v1.1.z and older versions from OADP.v1.0.z.
  • The stable-1.0 channel is deprecated and is not supported.
  • The stable-1.1 channel is deprecated and is not supported.
  • The stable-1.2 channel is deprecated and is not supported.
  • The stable-1.3 channel contains OADP.v1.3.z, the most recent OADP 1.3 ClusterServiceVersion.
  • The stable-1.4 channel contains OADP.v1.4.z, the most recent OADP 1.4 ClusterServiceVersion.

For more information, see OpenShift Operator Life Cycles.

Which update channel is right for you?

  • The stable channel is now deprecated. If you are already using the stable channel, you will continue to get updates from OADP.v1.1.z.
  • Choose the stable-1.y update channel to install OADP 1.y and to continue receiving patches for it. If you choose this channel, you will receive all z-stream patches for version 1.y.z.

When must you switch update channels?

  • If you have OADP 1.y installed, and you want to receive patches only for that y-stream, you must switch from the stable update channel to the stable-1.y update channel. You will then receive all z-stream patches for version 1.y.z.
  • If you have OADP 1.0 installed, want to upgrade to OADP 1.1, and then receive patches only for OADP 1.1, you must switch from the stable-1.0 update channel to the stable-1.1 update channel. You will then receive all z-stream patches for version 1.1.z.
  • If you have OADP 1.y installed, with y greater than 0, and want to switch to OADP 1.0, you must uninstall your OADP Operator and then reinstall it using the stable-1.0 update channel. You will then receive all z-stream patches for version 1.0.z.
Note

You cannot switch from OADP 1.y to OADP 1.0 by switching update channels. You must uninstall the Operator and then reinstall it.

4.4.1.4. Installation of OADP on multiple namespaces

You can install OpenShift API for Data Protection (OADP) into multiple namespaces on the same cluster so that multiple project owners can manage their own OADP instance. This use case has been validated with File System Backup (FSB) and Container Storage Interface (CSI).

You install each instance of OADP as specified by the per-platform procedures contained in this document with the following additional requirements:

  • All deployments of OADP on the same cluster must be the same version, for example, 1.1.4. Installing different versions of OADP on the same cluster is not supported.
  • Each individual deployment of OADP must have a unique set of credentials and at least one BackupStorageLocation configuration. You can also use multiple BackupStorageLocation configurations within the same namespace.
  • By default, each OADP deployment has cluster-level access across namespaces. OpenShift Container Platform administrators need to review security and RBAC settings carefully and make any necessary changes to them to ensure that each OADP instance has the correct permissions.

4.4.1.5. Velero CPU and memory requirements based on collected data

The following recommendations are based on observations of performance made in the scale and performance lab. The backup and restore resources can be impacted by the type of plugin, the amount of resources required by that backup or restore, and the respective data contained in the persistent volumes (PVs) related to those resources.

10m - average usage

60m - large usage

  1. Average usage - use these settings for most usage situations.
  2. Large usage - use these settings for large usage situations, such as a large PV (500GB Usage), multiple namespaces (100+), or many pods within a single namespace (2000 pods+), and for optimal performance for backup and restore involving large datasets.
  3. Restic resource usage corresponds to the amount of data, and type of data. For example, many small files or large amounts of data can cause Restic to use large amounts of resources. The Velero documentation references 500m as a supplied default, for most of our testing we found a 200m request suitable with 1000m limit. As cited in the Velero documentation, exact CPU and memory usage is dependent on the scale of files and directories, in addition to environmental limitations.
  4. Increasing the CPU has a significant impact on improving backup and restore times.
  5. Data Mover - Data Mover default resourceTimeout is 10m. Our tests show that for restoring a large PV (500GB usage), it is required to increase the resourceTimeout to 60m.
Note

The resource requirements listed throughout the guide are for average usage only. For large usage, adjust the settings as described in the table above.

4.4.1.5.2. NodeAgent CPU for large usage

Testing shows that increasing NodeAgent CPU can significantly improve backup and restore times when using OpenShift API for Data Protection (OADP).

Important

It is not recommended to use Kopia without limits in production environments on nodes running production workloads due to Kopia’s aggressive consumption of resources. However, running Kopia with limits that are too low results in CPU limiting and slow backups and restore situations. Testing showed that running Kopia with 20 cores and 32 Gi memory supported backup and restore operations of over 100 GB of data, multiple namespaces, or over 2000 pods in a single namespace.

Testing detected no CPU limiting or memory saturation with these resource specifications.

You can set these limits in Ceph MDS pods by following the procedure in Changing the CPU and memory resources on the rook-ceph pods.

You need to add the following lines to the storage cluster Custom Resource (CR) to set the limits: 

   resources:
     mds:
       limits:
         cpu: "3"
         memory: 128Gi
       requests:
         cpu: "3"
         memory: 8Gi

4.4.2. Installing the OADP Operator

You can install the OpenShift API for Data Protection (OADP) Operator on OpenShift Container Platform 4.15 by using Operator Lifecycle Manager (OLM).

The OADP Operator installs Velero 1.14.

4.4.3. Configuring the OpenShift API for Data Protection with AWS S3 compatible storage

You install the OpenShift API for Data Protection (OADP) with Amazon Web Services (AWS) S3 compatible storage by installing the OADP Operator. The Operator installs Velero 1.14.

IBM Cloud® S3 is supported as an AWS S3 compatible backup storage provider.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You configure AWS for Velero, create a default Secret, and then install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.

4.4.3.1. Configuring Amazon Web Services

You configure Amazon Web Services (AWS) for the OpenShift API for Data Protection (OADP).

Prerequisites

  • You must have the AWS CLI installed.

Procedure

  1. Set the BUCKET variable: 

    $ BUCKET=<your_bucket>

  2. Set the REGION variable: 

    $ REGION=<your_region>

  3. Create an AWS S3 bucket: 

    $ aws s3api create-bucket \
    --bucket $BUCKET \
    --region $REGION \
    --create-bucket-configuration LocationConstraint=$REGION 1
    1
    us-east-1 does not support a LocationConstraint. If your region is us-east-1, omit --create-bucket-configuration LocationConstraint=$REGION.

  4. Create an IAM user: 

    $ aws iam create-user --user-name velero 1
    1
    If you want to use Velero to back up multiple clusters with multiple S3 buckets, create a unique user name for each cluster.

  5. Create a velero-policy.json file: 

    $ cat > velero-policy.json <<EOF

            ],
            "Resource": [
                "arn:aws:s3:::${BUCKET}"
            ]
        }
    ]
}
EOF

  6. Attach the policies to give the velero user the minimum necessary permissions: 

    $ aws iam put-user-policy \
  --user-name velero \
  --policy-name velero \
  --policy-document file://velero-policy.json

  7. Create an access key for the velero user: 

    $ aws iam create-access-key --user-name velero

    Example output

    {
  "AccessKey": {
        "UserName": "velero",
        "Status": "Active",
        "CreateDate": "2017-07-31T22:24:41.576Z",
        "SecretAccessKey": <AWS_SECRET_ACCESS_KEY>,
        "AccessKeyId": <AWS_ACCESS_KEY_ID>
  }
}

  8. Create a credentials-velero file: 

    $ cat << EOF > ./credentials-velero
[default]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>
EOF

    You use the credentials-velero file to create a Secret object for AWS before you install the Data Protection Application.

4.4.3.2. About backup and snapshot locations and their secrets

You specify backup and snapshot locations and their secrets in the DataProtectionApplication custom resource (CR).

Backup locations

You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.

Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.

Snapshot locations

If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.

If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass CR to register the CSI driver.

If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.

Secrets

If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret.

If the backup and snapshot locations use different credentials, you create two secret objects:

  • Custom Secret for the backup location, which you specify in the DataProtectionApplication CR.
  • Default Secret for the snapshot location, which is not referenced in the DataProtectionApplication CR.
Important

The Data Protection Application requires a default Secret. Otherwise, the installation will fail.

If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file.

4.4.3.2.1. Creating a default Secret

You create a default Secret if your backup and snapshot locations use the same credentials or if you do not require a snapshot location.

The default name of the Secret is cloud-credentials.

Note

The DataProtectionApplication custom resource (CR) requires a default Secret. Otherwise, the installation will fail. If the name of the backup location Secret is not specified, the default name is used.

If you do not want to use the backup location credentials during the installation, you can create a Secret with the default name by using an empty credentials-velero file.

Prerequisites

  • Your object storage and cloud storage, if any, must use the same credentials.
  • You must configure object storage for Velero.
  • You must create a credentials-velero file for the object storage in the appropriate format.

Procedure

  • Create a Secret with the default name: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero

The Secret is referenced in the spec.backupLocations.credential block of the DataProtectionApplication CR when you install the Data Protection Application.

4.4.3.2.2. Creating profiles for different credentials

If your backup and snapshot locations use different credentials, you create separate profiles in the credentials-velero file.

Then, you create a Secret object and specify the profiles in the DataProtectionApplication custom resource (CR).

Procedure

  1. Create a credentials-velero file with separate profiles for the backup and snapshot locations, as in the following example: 

    [backupStorage]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>

[volumeSnapshot]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>

  2. Create a Secret object with the credentials-velero file: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero 1

  3. Add the profiles to the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
        config:
          region: us-east-1
          profile: "backupStorage"
        credential:
          key: cloud
          name: cloud-credentials
  snapshotLocations:
    - velero:
        provider: aws
        config:
          region: us-west-2
          profile: "volumeSnapshot"
4.4.3.2.3. Creating an OADP SSE-C encryption key for additional data security

Amazon Web Services (AWS) S3 applies server-side encryption with Amazon S3 managed keys (SSE-S3) as the base level of encryption for every bucket in Amazon S3.

OpenShift API for Data Protection (OADP) encrypts data by using SSL/TLS, HTTPS, and the velero-repo-credentials secret when transferring the data from a cluster to storage. To protect backup data in case of lost or stolen AWS credentials, apply an additional layer of encryption.

The velero-plugin-for-aws plugin provides several additional encryption methods. You should review its configuration options and consider implementing additional encryption.

You can store your own encryption keys by using server-side encryption with customer-provided keys (SSE-C). This feature provides additional security if your AWS credentials become exposed.

Warning

Be sure to store cryptographic keys in a secure and safe manner. Encrypted data and backups cannot be recovered if you do not have the encryption key.

Prerequisites

  • To make OADP mount a secret that contains your SSE-C key to the Velero pod at /credentials, use the following default secret name for AWS: cloud-credentials, and leave at least one of the following labels empty:

Note

The following procedure contains an example of a spec:backupLocations block that does not specify credentials. This example would trigger an OADP secret mounting.

  • If you need the backup location to have credentials with a different name than cloud-credentials, you must add a snapshot location, such as the one in the following example, that does not contain a credential name. Because the example does not contain a credential name, the snapshot location will use cloud-credentials as its secret for taking snapshots.

Example snapshot location in a DPA without credentials specified

 snapshotLocations:
  - velero:
      config:
        profile: default
        region: <region>
      provider: aws
# ...

Procedure

  1. Create an SSE-C encryption key:

    1. Generate a random number and save it as a file named sse.key by running the following command: 

      $ dd if=/dev/urandom bs=1 count=32 > sse.key

    2. Encode the sse.key by using Base64 and save the result as a file named sse_encoded.key by running the following command: 

      $ cat sse.key | base64 > sse_encoded.key

    3. Link the file named sse_encoded.key to a new file named customer-key by running the following command: 

      $ ln -s sse_encoded.key customer-key

  2. Create an OpenShift Container Platform secret:

    • If you are initially installing and configuring OADP, create the AWS credential and encryption key secret at the same time by running the following command: 

      $ oc create secret generic cloud-credentials --namespace openshift-adp --from-file cloud=<path>/openshift_aws_credentials,customer-key=<path>/sse_encoded.key

    • If you are updating an existing installation, edit the values of the cloud-credential secret block of the DataProtectionApplication CR manifest, as in the following example: 

      apiVersion: v1
data:
  cloud: W2Rfa2V5X2lkPSJBS0lBVkJRWUIyRkQ0TlFHRFFPQiIKYXdzX3NlY3JldF9hY2Nlc3Nfa2V5P<snip>rUE1mNWVSbTN5K2FpeWhUTUQyQk1WZHBOIgo=
  customer-key: v+<snip>TFIiq6aaXPbj8dhos=
kind: Secret
# ...

  3. Edit the value of the customerKeyEncryptionFile attribute in the backupLocations block of the DataProtectionApplication CR manifest, as in the following example: 

    spec:
  backupLocations:
    - velero:
        config:
          customerKeyEncryptionFile: /credentials/customer-key
          profile: default
# ...
    Warning

    You must restart the Velero pod to remount the secret credentials properly on an existing installation.

    The installation is complete, and you can back up and restore OpenShift Container Platform resources. The data saved in AWS S3 storage is encrypted with the new key, and you cannot download it from the AWS S3 console or API without the additional encryption key.

Verification

To verify that you cannot download the encrypted files without the inclusion of an additional key, create a test file, upload it, and then try to download it.

  1. Create a test file by running the following command: 

    $ echo "encrypt me please" > test.txt

  2. Upload the test file by running the following command: 

    $ aws s3api put-object \
  --bucket <bucket> \
  --key test.txt \
  --body test.txt \
  --sse-customer-key fileb://sse.key \
  --sse-customer-algorithm AES256

  3. Try to download the file. In either the Amazon web console or the terminal, run the following command: 

    $ s3cmd get s3://<bucket>/test.txt test.txt

    The download fails because the file is encrypted with an additional key.

  4. Download the file with the additional encryption key by running the following command: 

    $ aws s3api get-object \
    --bucket <bucket> \
    --key test.txt \
    --sse-customer-key fileb://sse.key \
    --sse-customer-algorithm AES256 \
    downloaded.txt

  5. Read the file contents by running the following command: 

    $ cat downloaded.txt

    Example output

    encrypt me please

Additional resources

You can also download the file with the additional encryption key backed up with Velcro by running a different command. See Downloading a file with an SSE-C encryption key for files backed up by Velero.

4.4.3.2.3.1. Downloading a file with an SSE-C encryption key for files backed up by Velero

When you are verifying an SSE-C encryption key, you can also download the file with the additional encryption key for files that were backed up with Velcro.

Procedure

  • Download the file with the additional encryption key for files backed up by Velero by running the following command: 
$ aws s3api get-object \
  --bucket <bucket> \
  --key velero/backups/mysql-persistent-customerkeyencryptionfile4/mysql-persistent-customerkeyencryptionfile4.tar.gz \
  --sse-customer-key fileb://sse.key \
  --sse-customer-algorithm AES256 \
  --debug \
  velero_download.tar.gz
4.4.3.3. Configuring the Data Protection Application

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.

4.4.3.3.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1 1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

Use the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.

For more details, see Configuring node agents and node labels.

4.4.3.3.2. Enabling self-signed CA certificates

You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication custom resource (CR) manifest to prevent a certificate signed by unknown authority error.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the spec.backupLocations.velero.objectStorage.caCert parameter and spec.backupLocations.velero.config parameters of the DataProtectionApplication CR manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket>
          prefix: <prefix>
          caCert: <base64_encoded_cert_string> 1
        config:
          insecureSkipTLSVerify: "false" 2
# ...
    1
    Specify the Base64-encoded CA certificate string.
    2
    The insecureSkipTLSVerify configuration can be set to either "true" or "false". If set to "true", SSL/TLS security is disabled. If set to "false", SSL/TLS security is enabled.
4.4.3.3.2.1. Using CA certificates with the velero command aliased for Velero deployment

You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.

Prerequisites

  • You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role.

  • You must have the OpenShift CLI (oc) installed.

    1. To use an aliased Velero command, run the following command: 

      $ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'

    2. Check that the alias is working by running the following command:

      Example

      $ velero version
Client:
	Version: v1.12.1-OADP
	Git commit: -
Server:
	Version: v1.12.1-OADP

    3. To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands: 

      $ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')

$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
      $ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt

    4. To fetch the backup logs, run the following command: 

      $ velero backup logs  <backup_name>  --cacert /tmp/<your_cacert.txt>

      You can use these logs to view failures and warnings for the resources that you cannot back up.

    5. If the Velero pod restarts, the /tmp/your-cacert.txt file disappears, and you must re-create the /tmp/your-cacert.txt file by re-running the commands from the previous step.

    6. You can check if the /tmp/your-cacert.txt file still exists, in the file location where you stored it, by running the following command: 

      $ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"
/tmp/your-cacert.txt

In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.

4.4.3.4. Installing the Data Protection Application 1.2 and earlier

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

  • If the backup and snapshot locations use different credentials, you must create a Secret with the default name, cloud-credentials, which contains separate profiles for the backup and snapshot location credentials.

    Note

    If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

    Note

    Velero creates a secret named velero-repo-credentials in the OADP namespace, which contains a default backup repository password. You can update the secret with your own password encoded as base64 before you run your first backup targeted to the backup repository. The value of the key to update is Data[repository-password].

    After you create your DPA, the first time that you run a backup targeted to the backup repository, Velero creates a backup repository whose secret is velero-repo-credentials, which contains either the default password or the one you replaced it with. If you update the secret password after the first backup, the new password will not match the password in velero-repo-credentials, and therefore, Velero will not be able to connect with the older backups.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
  configuration:
    velero:
      defaultPlugins:
        - openshift 1
        - aws
      resourceTimeout: 10m 2
    restic:
      enable: true 3
      podConfig:
        nodeSelector: <node_selector> 4
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket_name> 5
          prefix: <prefix> 6
        config:
          region: <region>
          profile: "default"
          s3ForcePathStyle: "true" 7
          s3Url: <s3_url> 8
        credential:
          key: cloud
          name: cloud-credentials 9
  snapshotLocations: 10
    - velero:
        provider: aws
        config:
          region: <region> 11
          profile: "default"
        credential:
          key: cloud
          name: cloud-credentials 12
    1
    The openshift plugin is mandatory.
    2
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    3
    Set this value to false if you want to disable the Restic installation. Restic deploys a daemon set, which means that Restic pods run on each working node. In OADP version 1.2 and later, you can configure Restic for backups by adding spec.defaultVolumesToFsBackup: true to the Backup CR. In OADP version 1.1, add spec.defaultVolumesToRestic: true to the Backup CR.
    4
    Specify on which nodes Restic is available. By default, Restic runs on all nodes.
    5
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    6
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
    7
    Specify whether to force path style URLs for S3 objects (Boolean). Not Required for AWS S3. Required only for S3 compatible storage.
    8
    Specify the URL of the object store that you are using to store backups. Not required for AWS S3. Required only for S3 compatible storage.
    9
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the backup location.
    10
    Specify a snapshot location, unless you use CSI snapshots or Restic to back up PVs.
    11
    The snapshot location must be in the same region as the PVs.
    12
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the snapshot location. If your backup and snapshot locations use different credentials, create separate profiles in the credentials-velero file.
  4. Click Create.

4.4.3.5. Installing the Data Protection Application 1.3

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

  • If the backup and snapshot locations use different credentials, you must create a Secret with the default name, cloud-credentials, which contains separate profiles for the backup and snapshot location credentials.

    Note

    If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp 1
spec:
  configuration:
    velero:
      defaultPlugins:
        - openshift 2
        - aws
      resourceTimeout: 10m 3
    nodeAgent: 4
      enable: true 5
      uploaderType: kopia 6
      podConfig:
        nodeSelector: <node_selector> 7
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket_name> 8
          prefix: <prefix> 9
        config:
          region: <region>
          profile: "default"
          s3ForcePathStyle: "true" 10
          s3Url: <s3_url> 11
        credential:
          key: cloud
          name: cloud-credentials 12
  snapshotLocations: 13
    - name: default
      velero:
        provider: aws
        config:
          region: <region> 14
          profile: "default"
        credential:
          key: cloud
          name: cloud-credentials 15
    1
    The default namespace for OADP is openshift-adp. The namespace is a variable and is configurable.
    2
    The openshift plugin is mandatory.
    3
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    4
    The administrative agent that routes the administrative requests to servers.
    5
    Set this value to true if you want to enable nodeAgent and perform File System Backup.
    6
    Enter kopia or restic as your uploader. You cannot change the selection after the installation. For the Built-in DataMover you must use Kopia. The nodeAgent deploys a daemon set, which means that the nodeAgent pods run on each working node. You can configure File System Backup by adding spec.defaultVolumesToFsBackup: true to the Backup CR.
    7
    Specify the nodes on which Kopia or Restic are available. By default, Kopia or Restic run on all nodes.
    8
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    9
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
    10
    Specify whether to force path style URLs for S3 objects (Boolean). Not Required for AWS S3. Required only for S3 compatible storage.
    11
    Specify the URL of the object store that you are using to store backups. Not required for AWS S3. Required only for S3 compatible storage.
    12
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the backup location.
    13
    Specify a snapshot location, unless you use CSI snapshots or a File System Backup (FSB) to back up PVs.
    14
    The snapshot location must be in the same region as the PVs.
    15
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the snapshot location. If your backup and snapshot locations use different credentials, create separate profiles in the credentials-velero file.
  4. Click Create.

Verification

  1. Verify the installation by viewing the OpenShift API for Data Protection (OADP) resources by running the following command: 

    $ oc get all -n openshift-adp

    Example output

  2. Verify that the DataProtectionApplication (DPA) is reconciled by running the following command: 

    $ oc get dpa dpa-sample -n openshift-adp -o jsonpath='{.status}'

    Example output

    {"conditions":[{"lastTransitionTime":"2023-10-27T01:23:57Z","message":"Reconcile complete","reason":"Complete","status":"True","type":"Reconciled"}]}

  3. Verify the type is set to Reconciled.

  4. Verify the backup storage location and confirm that the PHASE is Available by running the following command: 

    $ oc get backupStorageLocation -n openshift-adp

    Example output

    NAME           PHASE       LAST VALIDATED   AGE     DEFAULT
dpa-sample-1   Available   1s               3d16h   true

4.4.3.5.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.3.6. Configuring the backup storage location with a MD5 checksum algorithm

You can configure the Backup Storage Location (BSL) in the Data Protection Application (DPA) to use a MD5 checksum algorithm for both Amazon Simple Storage Service (Amazon S3) and S3-compatible storage providers. The checksum algorithm calculates the checksum for uploading and downloading objects to Amazon S3. You can use one of the following options to set the checksumAlgorithm field in the spec.backupLocations.velero.config.checksumAlgorithm section of the DPA.

  • CRC32
  • CRC32C
  • SHA1
  • SHA256
Note

You can also set the checksumAlgorithm field to an empty value to skip the MD5 checksum check.

If you do not set a value for the checksumAlgorithm field, then the default value is set to CRC32.

Prerequisites

  • You have installed the OADP Operator.
  • You have configured Amazon S3, or S3-compatible object storage as a backup location.

Procedure

  • Configure the BSL in the DPA as shown in the following example:

    Example Data Protection Application

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: test-dpa
  namespace: openshift-adp
spec:
  backupLocations:
  - name: default
    velero:
      config:
        checksumAlgorithm: "" 1
        insecureSkipTLSVerify: "true"
        profile: "default"
        region: <bucket_region>
        s3ForcePathStyle: "true"
        s3Url: <bucket_url>
      credential:
        key: cloud
        name: cloud-credentials
      default: true
      objectStorage:
        bucket: <bucket_name>
        prefix: velero
      provider: aws
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - aws
      - csi

    1
    Specify the checksumAlgorithm. In this example, the checksumAlgorithm field is set to an empty value. You can select an option from the following list: CRC32, CRC32C, SHA1, SHA256.
Important

If you are using Noobaa as the object storage provider, and you do not set the spec.backupLocations.velero.config.checksumAlgorithm field in the DPA, an empty value of checksumAlgorithm is added to the BSL configuration.

The empty value is only added for BSLs that are created using the DPA. This value is not added if you create the BSL by using any other method.

4.4.3.7. Configuring the DPA with more than one BSL

You can configure the DPA with more than one BSL and specify the credentials provided by the cloud provider.

Prerequisites

  • You must install the OADP Operator.
  • You must create the secrets by using the credentials provided by the cloud provider.

Procedure

  1. Configure the DPA with more than one BSL. See the following example.

    Example DPA

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
#...
backupLocations:
  - name: aws 1
    velero:
      provider: aws
      default: true 2
      objectStorage:
        bucket: <bucket_name> 3
        prefix: <prefix> 4
      config:
        region: <region_name> 5
        profile: "default"
      credential:
        key: cloud
        name: cloud-credentials 6
  - name: odf 7
    velero:
      provider: aws
      default: false
      objectStorage:
        bucket: <bucket_name>
        prefix: <prefix>
      config:
        profile: "default"
        region: <region_name>
        s3Url: <url> 8
        insecureSkipTLSVerify: "true"
        s3ForcePathStyle: "true"
      credential:
        key: cloud
        name: <custom_secret_name_odf> 9
#...

    1
    Specify a name for the first BSL.
    2
    This parameter indicates that this BSL is the default BSL. If a BSL is not set in the Backup CR, the default BSL is used. You can set only one BSL as the default.
    3
    Specify the bucket name.
    4
    Specify a prefix for Velero backups; for example, velero.
    5
    Specify the AWS region for the bucket.
    6
    Specify the name of the default Secret object that you created.
    7
    Specify a name for the second BSL.
    8
    Specify the URL of the S3 endpoint.
    9
    Specify the correct name for the Secret; for example, custom_secret_name_odf. If you do not specify a Secret name, the default name is used.

  2. Specify the BSL to be used in the backup CR. See the following example.

    Example backup CR

    apiVersion: velero.io/v1
kind: Backup
# ...
spec:
  includedNamespaces:
  - <namespace> 1
  storageLocation: <backup_storage_location> 2
  defaultVolumesToFsBackup: true

    1
    Specify the namespace to back up.
    2
    Specify the storage location.
4.4.3.7.1. Enabling CSI in the DataProtectionApplication CR

You enable the Container Storage Interface (CSI) in the DataProtectionApplication custom resource (CR) in order to back up persistent volumes with CSI snapshots.

Prerequisites

  • The cloud provider must support CSI snapshots.

Procedure

  • Edit the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - csi 1
    1
    Add the csi default plugin.
4.4.3.7.2. Disabling the node agent in DataProtectionApplication

If you are not using Restic, Kopia, or DataMover for your backups, you can disable the nodeAgent field in the DataProtectionApplication custom resource (CR). Before you disable nodeAgent, ensure the OADP Operator is idle and not running any backups.

Procedure

  1. To disable the nodeAgent, set the enable flag to false. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: false  1
    uploaderType: kopia
# ...

    1
    Disables the node agent.

  2. To enable the nodeAgent, set the enable flag to true. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: true  1
    uploaderType: kopia
# ...

    1
    Enables the node agent.

You can set up a job to enable and disable the nodeAgent field in the DataProtectionApplication CR. For more information, see "Running tasks in pods using jobs".

Additional resources

4.4.4. Configuring the OpenShift API for Data Protection with Microsoft Azure

You install the OpenShift API for Data Protection (OADP) with Microsoft Azure by installing the OADP Operator. The Operator installs Velero 1.14.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You configure Azure for Velero, create a default Secret, and then install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.

4.4.4.1. Configuring Microsoft Azure

You configure Microsoft Azure for OpenShift API for Data Protection (OADP).

Prerequisites

Tools that use Azure services should always have restricted permissions to make sure that Azure resources are safe. Therefore, instead of having applications sign in as a fully privileged user, Azure offers service principals. An Azure service principal is a name that can be used with applications, hosted services, or automated tools.

This identity is used for access to resources.

  • Create a service principal
  • Sign in using a service principal and password
  • Sign in using a service principal and certificate
  • Manage service principal roles
  • Create an Azure resource using a service principal
  • Reset service principal credentials

For more details, see Create an Azure service principal with Azure CLI.

4.4.4.2. About backup and snapshot locations and their secrets

You specify backup and snapshot locations and their secrets in the DataProtectionApplication custom resource (CR).

Backup locations

You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.

Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.

Snapshot locations

If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.

If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass CR to register the CSI driver.

If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.

Secrets

If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret.

If the backup and snapshot locations use different credentials, you create two secret objects:

  • Custom Secret for the backup location, which you specify in the DataProtectionApplication CR.
  • Default Secret for the snapshot location, which is not referenced in the DataProtectionApplication CR.
Important

The Data Protection Application requires a default Secret. Otherwise, the installation will fail.

If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file.

4.4.4.2.1. Creating a default Secret

You create a default Secret if your backup and snapshot locations use the same credentials or if you do not require a snapshot location.

The default name of the Secret is cloud-credentials-azure.

Note

The DataProtectionApplication custom resource (CR) requires a default Secret. Otherwise, the installation will fail. If the name of the backup location Secret is not specified, the default name is used.

If you do not want to use the backup location credentials during the installation, you can create a Secret with the default name by using an empty credentials-velero file.

Prerequisites

  • Your object storage and cloud storage, if any, must use the same credentials.
  • You must configure object storage for Velero.
  • You must create a credentials-velero file for the object storage in the appropriate format.

Procedure

  • Create a Secret with the default name: 

    $ oc create secret generic cloud-credentials-azure -n openshift-adp --from-file cloud=credentials-velero

The Secret is referenced in the spec.backupLocations.credential block of the DataProtectionApplication CR when you install the Data Protection Application.

4.4.4.2.2. Creating secrets for different credentials

If your backup and snapshot locations use different credentials, you must create two Secret objects:

  • Backup location Secret with a custom name. The custom name is specified in the spec.backupLocations block of the DataProtectionApplication custom resource (CR).
  • Snapshot location Secret with the default name, cloud-credentials-azure. This Secret is not specified in the DataProtectionApplication CR.

Procedure

  1. Create a credentials-velero file for the snapshot location in the appropriate format for your cloud provider.

  2. Create a Secret for the snapshot location with the default name: 

    $ oc create secret generic cloud-credentials-azure -n openshift-adp --from-file cloud=credentials-velero
  3. Create a credentials-velero file for the backup location in the appropriate format for your object storage.

  4. Create a Secret for the backup location with a custom name: 

    $ oc create secret generic <custom_secret> -n openshift-adp --from-file cloud=credentials-velero

  5. Add the Secret with the custom name to the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
...
  backupLocations:
    - velero:
        config:
          resourceGroup: <azure_resource_group>
          storageAccount: <azure_storage_account_id>
          subscriptionId: <azure_subscription_id>
          storageAccountKeyEnvVar: AZURE_STORAGE_ACCOUNT_ACCESS_KEY
        credential:
          key: cloud
          name: <custom_secret> 1
        provider: azure
        default: true
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
  snapshotLocations:
    - velero:
        config:
          resourceGroup: <azure_resource_group>
          subscriptionId: <azure_subscription_id>
          incremental: "true"
        provider: azure
    1
    Backup location Secret with custom name.
4.4.4.3. Configuring the Data Protection Application

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.

4.4.4.3.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

Use the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.

For more details, see Configuring node agents and node labels.

4.4.4.3.2. Enabling self-signed CA certificates

You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication custom resource (CR) manifest to prevent a certificate signed by unknown authority error.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the spec.backupLocations.velero.objectStorage.caCert parameter and spec.backupLocations.velero.config parameters of the DataProtectionApplication CR manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket>
          prefix: <prefix>
          caCert: <base64_encoded_cert_string> 1
        config:
          insecureSkipTLSVerify: "false" 2
# ...
    1
    Specify the Base64-encoded CA certificate string.
    2
    The insecureSkipTLSVerify configuration can be set to either "true" or "false". If set to "true", SSL/TLS security is disabled. If set to "false", SSL/TLS security is enabled.
4.4.4.3.2.1. Using CA certificates with the velero command aliased for Velero deployment

You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.

Prerequisites

  • You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role.

  • You must have the OpenShift CLI (oc) installed.

    1. To use an aliased Velero command, run the following command: 

      $ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'

    2. Check that the alias is working by running the following command:

      Example

      $ velero version
Client:
	Version: v1.12.1-OADP
	Git commit: -
Server:
	Version: v1.12.1-OADP

    3. To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands: 

      $ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')

$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
      $ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt

    4. To fetch the backup logs, run the following command: 

      $ velero backup logs  <backup_name>  --cacert /tmp/<your_cacert.txt>

      You can use these logs to view failures and warnings for the resources that you cannot back up.

    5. If the Velero pod restarts, the /tmp/your-cacert.txt file disappears, and you must re-create the /tmp/your-cacert.txt file by re-running the commands from the previous step.

    6. You can check if the /tmp/your-cacert.txt file still exists, in the file location where you stored it, by running the following command: 

      $ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"
/tmp/your-cacert.txt

In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.

4.4.4.4. Installing the Data Protection Application 1.2 and earlier

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials-azure.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.

    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.

      Note

      If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

      Note

      Velero creates a secret named velero-repo-credentials in the OADP namespace, which contains a default backup repository password. You can update the secret with your own password encoded as base64 before you run your first backup targeted to the backup repository. The value of the key to update is Data[repository-password].

      After you create your DPA, the first time that you run a backup targeted to the backup repository, Velero creates a backup repository whose secret is velero-repo-credentials, which contains either the default password or the one you replaced it with. If you update the secret password after the first backup, the new password will not match the password in velero-repo-credentials, and therefore, Velero will not be able to connect with the older backups.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp

  snapshotLocations: 11
    - velero:
        config:
          resourceGroup: <azure_resource_group>
          subscriptionId: <azure_subscription_id>
          incremental: "true"
        name: default
        provider: azure
        credential:
          key: cloud
          name: cloud-credentials-azure 12
    1
    The openshift plugin is mandatory.
    2
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    3
    Set this value to false if you want to disable the Restic installation. Restic deploys a daemon set, which means that Restic pods run on each working node. In OADP version 1.2 and later, you can configure Restic for backups by adding spec.defaultVolumesToFsBackup: true to the Backup CR. In OADP version 1.1, add spec.defaultVolumesToRestic: true to the Backup CR.
    4
    Specify on which nodes Restic is available. By default, Restic runs on all nodes.
    5
    Specify the Azure resource group.
    6
    Specify the Azure storage account ID.
    7
    Specify the Azure subscription ID.
    8
    If you do not specify this value, the default name, cloud-credentials-azure, is used. If you specify a custom name, the custom name is used for the backup location.
    9
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    10
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
    11
    You do not need to specify a snapshot location if you use CSI snapshots or Restic to back up PVs.
    12
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials-azure, is used. If you specify a custom name, the custom name is used for the backup location.
  4. Click Create.

4.4.4.5.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.4.5.2. Enabling CSI in the DataProtectionApplication CR

You enable the Container Storage Interface (CSI) in the DataProtectionApplication custom resource (CR) in order to back up persistent volumes with CSI snapshots.

Prerequisites

  • The cloud provider must support CSI snapshots.

Procedure

  • Edit the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - csi 1
    1
    Add the csi default plugin.
4.4.4.5.3. Disabling the node agent in DataProtectionApplication

If you are not using Restic, Kopia, or DataMover for your backups, you can disable the nodeAgent field in the DataProtectionApplication custom resource (CR). Before you disable nodeAgent, ensure the OADP Operator is idle and not running any backups.

Procedure

  1. To disable the nodeAgent, set the enable flag to false. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: false  1
    uploaderType: kopia
# ...

    1
    Disables the node agent.

  2. To enable the nodeAgent, set the enable flag to true. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: true  1
    uploaderType: kopia
# ...

    1
    Enables the node agent.

You can set up a job to enable and disable the nodeAgent field in the DataProtectionApplication CR. For more information, see "Running tasks in pods using jobs".

Additional resources

4.4.5. Configuring the OpenShift API for Data Protection with Google Cloud Platform

You install the OpenShift API for Data Protection (OADP) with Google Cloud Platform (GCP) by installing the OADP Operator. The Operator installs Velero 1.14.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You configure GCP for Velero, create a default Secret, and then install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.

4.4.5.1. Configuring Google Cloud Platform

You configure Google Cloud Platform (GCP) for the OpenShift API for Data Protection (OADP).

Prerequisites

Procedure

  1. Log in to GCP: 

    $ gcloud auth login

  2. Set the BUCKET variable: 

    $ BUCKET=<bucket> 1
    1
    Specify your bucket name.

  3. Create the storage bucket: 

    $ gsutil mb gs://$BUCKET/

  4. Set the PROJECT_ID variable to your active project: 

    $ PROJECT_ID=$(gcloud config get-value project)

  5. Create a service account: 

    $ gcloud iam service-accounts create velero \
    --display-name "Velero service account"

  6. List your service accounts: 

    $ gcloud iam service-accounts list

  7. Set the SERVICE_ACCOUNT_EMAIL variable to match its email value: 

    $ SERVICE_ACCOUNT_EMAIL=$(gcloud iam service-accounts list \
    --filter="displayName:Velero service account" \
    --format 'value(email)')

  8. Attach the policies to give the velero user the minimum necessary permissions: 

    $ ROLE_PERMISSIONS=(

    compute.snapshots.useReadOnly
    compute.snapshots.delete
    compute.zones.get
    storage.objects.create
    storage.objects.delete
    storage.objects.get
    storage.objects.list
    iam.serviceAccounts.signBlob
)

  9. Create the velero.server custom role: 

    $ gcloud iam roles create velero.server \
    --project $PROJECT_ID \
    --title "Velero Server" \
    --permissions "$(IFS=","; echo "${ROLE_PERMISSIONS[*]}")"

  10. Add IAM policy binding to the project: 

    $ gcloud projects add-iam-policy-binding $PROJECT_ID \
    --member serviceAccount:$SERVICE_ACCOUNT_EMAIL \
    --role projects/$PROJECT_ID/roles/velero.server

  11. Update the IAM service account: 

    $ gsutil iam ch serviceAccount:$SERVICE_ACCOUNT_EMAIL:objectAdmin gs://${BUCKET}

  12. Save the IAM service account keys to the credentials-velero file in the current directory: 

    $ gcloud iam service-accounts keys create credentials-velero \
    --iam-account $SERVICE_ACCOUNT_EMAIL

    You use the credentials-velero file to create a Secret object for GCP before you install the Data Protection Application.

4.4.5.2. About backup and snapshot locations and their secrets

You specify backup and snapshot locations and their secrets in the DataProtectionApplication custom resource (CR).

Backup locations

You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.

Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.

Snapshot locations

If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.

If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass CR to register the CSI driver.

If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.

Secrets

If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret.

If the backup and snapshot locations use different credentials, you create two secret objects:

  • Custom Secret for the backup location, which you specify in the DataProtectionApplication CR.
  • Default Secret for the snapshot location, which is not referenced in the DataProtectionApplication CR.
Important

The Data Protection Application requires a default Secret. Otherwise, the installation will fail.

If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file.

4.4.5.2.1. Creating a default Secret

You create a default Secret if your backup and snapshot locations use the same credentials or if you do not require a snapshot location.

The default name of the Secret is cloud-credentials-gcp.

Note

The DataProtectionApplication custom resource (CR) requires a default Secret. Otherwise, the installation will fail. If the name of the backup location Secret is not specified, the default name is used.

If you do not want to use the backup location credentials during the installation, you can create a Secret with the default name by using an empty credentials-velero file.

Prerequisites

  • Your object storage and cloud storage, if any, must use the same credentials.
  • You must configure object storage for Velero.
  • You must create a credentials-velero file for the object storage in the appropriate format.

Procedure

  • Create a Secret with the default name: 

    $ oc create secret generic cloud-credentials-gcp -n openshift-adp --from-file cloud=credentials-velero

The Secret is referenced in the spec.backupLocations.credential block of the DataProtectionApplication CR when you install the Data Protection Application.

4.4.5.2.2. Creating secrets for different credentials

If your backup and snapshot locations use different credentials, you must create two Secret objects:

  • Backup location Secret with a custom name. The custom name is specified in the spec.backupLocations block of the DataProtectionApplication custom resource (CR).
  • Snapshot location Secret with the default name, cloud-credentials-gcp. This Secret is not specified in the DataProtectionApplication CR.

Procedure

  1. Create a credentials-velero file for the snapshot location in the appropriate format for your cloud provider.

  2. Create a Secret for the snapshot location with the default name: 

    $ oc create secret generic cloud-credentials-gcp -n openshift-adp --from-file cloud=credentials-velero
  3. Create a credentials-velero file for the backup location in the appropriate format for your object storage.

  4. Create a Secret for the backup location with a custom name: 

    $ oc create secret generic <custom_secret> -n openshift-adp --from-file cloud=credentials-velero

  5. Add the Secret with the custom name to the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
...
  backupLocations:
    - velero:
        provider: gcp
        default: true
        credential:
          key: cloud
          name: <custom_secret> 1
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
  snapshotLocations:
    - velero:
        provider: gcp
        default: true
        config:
          project: <project>
          snapshotLocation: us-west1
    1
    Backup location Secret with custom name.
4.4.5.3. Configuring the Data Protection Application

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.

4.4.5.3.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

Use the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.

For more details, see Configuring node agents and node labels.

4.4.5.3.2. Enabling self-signed CA certificates

You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication custom resource (CR) manifest to prevent a certificate signed by unknown authority error.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the spec.backupLocations.velero.objectStorage.caCert parameter and spec.backupLocations.velero.config parameters of the DataProtectionApplication CR manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket>
          prefix: <prefix>
          caCert: <base64_encoded_cert_string> 1
        config:
          insecureSkipTLSVerify: "false" 2
# ...
    1
    Specify the Base64-encoded CA certificate string.
    2
    The insecureSkipTLSVerify configuration can be set to either "true" or "false". If set to "true", SSL/TLS security is disabled. If set to "false", SSL/TLS security is enabled.
4.4.5.3.2.1. Using CA certificates with the velero command aliased for Velero deployment

You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.

Prerequisites

  • You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role.

  • You must have the OpenShift CLI (oc) installed.

    1. To use an aliased Velero command, run the following command: 

      $ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'

    2. Check that the alias is working by running the following command:

      Example

      $ velero version
Client:
	Version: v1.12.1-OADP
	Git commit: -
Server:
	Version: v1.12.1-OADP

    3. To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands: 

      $ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')

$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
      $ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt

    4. To fetch the backup logs, run the following command: 

      $ velero backup logs  <backup_name>  --cacert /tmp/<your_cacert.txt>

      You can use these logs to view failures and warnings for the resources that you cannot back up.

    5. If the Velero pod restarts, the /tmp/your-cacert.txt file disappears, and you must re-create the /tmp/your-cacert.txt file by re-running the commands from the previous step.

    6. You can check if the /tmp/your-cacert.txt file still exists, in the file location where you stored it, by running the following command: 

      $ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"
/tmp/your-cacert.txt

In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.

4.4.5.4. Installing the Data Protection Application 1.2 and earlier

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials-gcp.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.

    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.

      Note

      If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

      Note

      Velero creates a secret named velero-repo-credentials in the OADP namespace, which contains a default backup repository password. You can update the secret with your own password encoded as base64 before you run your first backup targeted to the backup repository. The value of the key to update is Data[repository-password].

      After you create your DPA, the first time that you run a backup targeted to the backup repository, Velero creates a backup repository whose secret is velero-repo-credentials, which contains either the default password or the one you replaced it with. If you update the secret password after the first backup, the new password will not match the password in velero-repo-credentials, and therefore, Velero will not be able to connect with the older backups.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
  configuration:
    velero:
      defaultPlugins:
        - gcp
        - openshift 1
      resourceTimeout: 10m 2
    restic:
      enable: true 3
      podConfig:
        nodeSelector: <node_selector> 4
  backupLocations:
    - velero:
        provider: gcp
        default: true
        credential:
          key: cloud 5
          name: cloud-credentials-gcp 6
        objectStorage:
          bucket: <bucket_name> 7
          prefix: <prefix> 8
  snapshotLocations: 9
    - velero:
        provider: gcp
        default: true
        config:
          project: <project>
          snapshotLocation: us-west1 10
        credential:
          key: cloud
          name: cloud-credentials-gcp 11
    1
    The openshift plugin is mandatory.
    2
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    3
    Set this value to false if you want to disable the Restic installation. Restic deploys a daemon set, which means that Restic pods run on each working node. In OADP version 1.2 and later, you can configure Restic for backups by adding spec.defaultVolumesToFsBackup: true to the Backup CR. In OADP version 1.1, add spec.defaultVolumesToRestic: true to the Backup CR.
    4
    Specify on which nodes Restic is available. By default, Restic runs on all nodes.
    5
    Secret key that contains credentials. For Google workload identity federation cloud authentication use service_account.json.
    6
    Secret name that contains credentials. If you do not specify this value, the default name, cloud-credentials-gcp, is used.
    7
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    8
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
    9
    Specify a snapshot location, unless you use CSI snapshots or Restic to back up PVs.
    10
    The snapshot location must be in the same region as the PVs.
    11
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials-gcp, is used. If you specify a custom name, the custom name is used for the snapshot location.
  4. Click Create.

Verification

  1. Verify the installation by viewing the OpenShift API for Data Protection (OADP) resources by running the following command: 

    $ oc get all -n openshift-adp

    Example output

4.4.5.5. Google workload identity federation cloud authentication

Applications running outside Google Cloud use service account keys, such as usernames and passwords, to gain access to Google Cloud resources. These service account keys might become a security risk if they are not properly managed.

With Google’s workload identity federation, you can use Identity and Access Management (IAM) to offer IAM roles, including the ability to impersonate service accounts, to external identities. This eliminates the maintenance and security risks associated with service account keys.

Workload identity federation handles encrypting and decrypting certificates, extracting user attributes, and validation. Identity federation externalizes authentication, passing it over to Security Token Services (STS), and reduces the demands on individual developers. Authorization and controlling access to resources remain the responsibility of the application.

Note

Google workload identity federation is available for OADP 1.3.x and later.

When backing up volumes, OADP on GCP with Google workload identity federation authentication only supports CSI snapshots.

OADP on GCP with Google workload identity federation authentication does not support Volume Snapshot Locations (VSL) backups. For more details, see Google workload identity federation known issues.

If you do not use Google workload identity federation cloud authentication, continue to Installing the Data Protection Application.

Prerequisites

  • You have installed a cluster in manual mode with GCP Workload Identity configured.
  • You have access to the Cloud Credential Operator utility (ccoctl) and to the associated workload identity pool.

Procedure

  1. Create an oadp-credrequest directory by running the following command: 

    $ mkdir -p oadp-credrequest

  2. Create a CredentialsRequest.yaml file as following: 

    echo 'apiVersion: cloudcredential.openshift.io/v1
kind: CredentialsRequest
metadata:
  name: oadp-operator-credentials
  namespace: openshift-cloud-credential-operator
spec:
  providerSpec:
    apiVersion: cloudcredential.openshift.io/v1
    kind: GCPProviderSpec
    permissions:
    - compute.disks.get
    - compute.disks.create
    - compute.disks.createSnapshot

    - iam.serviceAccounts.signBlob
    skipServiceCheck: true
  secretRef:
    name: cloud-credentials-gcp
    namespace: <OPERATOR_INSTALL_NS>
  serviceAccountNames:
  - velero
' > oadp-credrequest/credrequest.yaml

  3. Use the ccoctl utility to process the CredentialsRequest objects in the oadp-credrequest directory by running the following command: 

    $ ccoctl gcp create-service-accounts \
    --name=<name> \
    --project=<gcp_project_id> \
    --credentials-requests-dir=oadp-credrequest \
    --workload-identity-pool=<pool_id> \
    --workload-identity-provider=<provider_id>

    The manifests/openshift-adp-cloud-credentials-gcp-credentials.yaml file is now available to use in the following steps.

  4. Create a namespace by running the following command: 

    $ oc create namespace <OPERATOR_INSTALL_NS>

  5. Apply the credentials to the namespace by running the following command: 

    $ oc apply -f manifests/openshift-adp-cloud-credentials-gcp-credentials.yaml
4.4.5.5.1. Google workload identity federation known issues
  • Volume Snapshot Location (VSL) backups finish with a PartiallyFailed phase when GCP workload identity federation is configured. Google workload identity federation authentication does not support VSL backups.
4.4.5.6. Installing the Data Protection Application 1.3

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials-gcp.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.
    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.
    Note

    If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest:

    Set this value to true if you want to enable nodeAgent and perform File System Backup.
    6
    Enter kopia or restic as your uploader. You cannot change the selection after the installation. For the Built-in DataMover you must use Kopia. The nodeAgent deploys a daemon set, which means that the nodeAgent pods run on each working node. You can configure File System Backup by adding spec.defaultVolumesToFsBackup: true to the Backup CR.
    7
    Specify the nodes on which Kopia or Restic are available. By default, Kopia or Restic run on all nodes.
    8
    Secret key that contains credentials. For Google workload identity federation cloud authentication use service_account.json.
    9
    Secret name that contains credentials. If you do not specify this value, the default name, cloud-credentials-gcp, is used.
    10
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    11
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
    12
    Specify a snapshot location, unless you use CSI snapshots or Restic to back up PVs.
    13
    The snapshot location must be in the same region as the PVs.
    14
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials-gcp, is used. If you specify a custom name, the custom name is used for the backup location.
    15
    Google workload identity federation supports internal image backup. Set this field to false if you do not want to use image backup.
  4. Click Create.

  2. Verify that the DataProtectionApplication (DPA) is reconciled by running the following command: 

    $ oc get dpa dpa-sample -n openshift-adp -o jsonpath='{.status}'

    Example output

    {"conditions":[{"lastTransitionTime":"2023-10-27T01:23:57Z","message":"Reconcile complete","reason":"Complete","status":"True","type":"Reconciled"}]}

  3. Verify the type is set to Reconciled.

  4. Verify the backup storage location and confirm that the PHASE is Available by running the following command: 

    $ oc get backupStorageLocation -n openshift-adp

    Example output

    NAME           PHASE       LAST VALIDATED   AGE     DEFAULT
dpa-sample-1   Available   1s               3d16h   true

4.4.5.6.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.5.6.2. Enabling CSI in the DataProtectionApplication CR

You enable the Container Storage Interface (CSI) in the DataProtectionApplication custom resource (CR) in order to back up persistent volumes with CSI snapshots.

Prerequisites

  • The cloud provider must support CSI snapshots.

Procedure

  • Edit the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - csi 1
    1
    Add the csi default plugin.
4.4.5.6.3. Disabling the node agent in DataProtectionApplication

If you are not using Restic, Kopia, or DataMover for your backups, you can disable the nodeAgent field in the DataProtectionApplication custom resource (CR). Before you disable nodeAgent, ensure the OADP Operator is idle and not running any backups.

Procedure

  1. To disable the nodeAgent, set the enable flag to false. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: false  1
    uploaderType: kopia
# ...

    1
    Disables the node agent.

  2. To enable the nodeAgent, set the enable flag to true. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: true  1
    uploaderType: kopia
# ...

    1
    Enables the node agent.

You can set up a job to enable and disable the nodeAgent field in the DataProtectionApplication CR. For more information, see "Running tasks in pods using jobs".

Additional resources

4.4.6. Configuring the OpenShift API for Data Protection with Multicloud Object Gateway

You install the OpenShift API for Data Protection (OADP) with Multicloud Object Gateway (MCG) by installing the OADP Operator. The Operator installs Velero 1.14.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You configure Multicloud Object Gateway as a backup location. MCG is a component of OpenShift Data Foundation. You configure MCG as a backup location in the DataProtectionApplication custom resource (CR).

Important

The CloudStorage API, which automates the creation of a bucket for object storage, is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

You create a Secret for the backup location and then you install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. For details, see Using Operator Lifecycle Manager on restricted networks.

4.4.6.1. Retrieving Multicloud Object Gateway credentials

You must retrieve the Multicloud Object Gateway (MCG) credentials, which you need to create a Secret custom resource (CR) for the OpenShift API for Data Protection (OADP).

Note

Although the MCG Operator is deprecated, the MCG plugin is still available for OpenShift Data Foundation. To download the plugin, browse to Download Red Hat OpenShift Data Foundation and download the appropriate MCG plugin for your operating system.

Prerequisites

Procedure

  1. Obtain the S3 endpoint, AWS_ACCESS_KEY_ID, and AWS_SECRET_ACCESS_KEY by running the describe command on the NooBaa custom resource.

  2. Create a credentials-velero file: 

    $ cat << EOF > ./credentials-velero
[default]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>
EOF

    You use the credentials-velero file to create a Secret object when you install the Data Protection Application.

4.4.6.2. About backup and snapshot locations and their secrets

You specify backup and snapshot locations and their secrets in the DataProtectionApplication custom resource (CR).

Backup locations

You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.

Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.

Snapshot locations

If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.

If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass CR to register the CSI driver.

If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.

Secrets

If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret.

If the backup and snapshot locations use different credentials, you create two secret objects:

  • Custom Secret for the backup location, which you specify in the DataProtectionApplication CR.
  • Default Secret for the snapshot location, which is not referenced in the DataProtectionApplication CR.
Important

The Data Protection Application requires a default Secret. Otherwise, the installation will fail.

If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file.

4.4.6.2.1. Creating a default Secret

You create a default Secret if your backup and snapshot locations use the same credentials or if you do not require a snapshot location.

The default name of the Secret is cloud-credentials.

Note

The DataProtectionApplication custom resource (CR) requires a default Secret. Otherwise, the installation will fail. If the name of the backup location Secret is not specified, the default name is used.

If you do not want to use the backup location credentials during the installation, you can create a Secret with the default name by using an empty credentials-velero file.

Prerequisites

  • Your object storage and cloud storage, if any, must use the same credentials.
  • You must configure object storage for Velero.
  • You must create a credentials-velero file for the object storage in the appropriate format.

Procedure

  • Create a Secret with the default name: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero

The Secret is referenced in the spec.backupLocations.credential block of the DataProtectionApplication CR when you install the Data Protection Application.

4.4.6.2.2. Creating secrets for different credentials

If your backup and snapshot locations use different credentials, you must create two Secret objects:

  • Backup location Secret with a custom name. The custom name is specified in the spec.backupLocations block of the DataProtectionApplication custom resource (CR).
  • Snapshot location Secret with the default name, cloud-credentials. This Secret is not specified in the DataProtectionApplication CR.

Procedure

  1. Create a credentials-velero file for the snapshot location in the appropriate format for your cloud provider.

  2. Create a Secret for the snapshot location with the default name: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero
  3. Create a credentials-velero file for the backup location in the appropriate format for your object storage.

  4. Create a Secret for the backup location with a custom name: 

    $ oc create secret generic <custom_secret> -n openshift-adp --from-file cloud=credentials-velero

  5. Add the Secret with the custom name to the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
...
  backupLocations:
    - velero:
        config:
          profile: "default"
          region: <region_name> 1
          s3Url: <url>
          insecureSkipTLSVerify: "true"
          s3ForcePathStyle: "true"
        provider: aws
        default: true
        credential:
          key: cloud
          name:  <custom_secret> 2
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
    1
    Specify the region, following the naming convention of the documentation of your object storage server.
    2
    Backup location Secret with custom name.
4.4.6.3. Configuring the Data Protection Application

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.

4.4.6.3.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

Use the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.

For more details, see Configuring node agents and node labels.

4.4.6.3.2. Enabling self-signed CA certificates

You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication custom resource (CR) manifest to prevent a certificate signed by unknown authority error.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the spec.backupLocations.velero.objectStorage.caCert parameter and spec.backupLocations.velero.config parameters of the DataProtectionApplication CR manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket>
          prefix: <prefix>
          caCert: <base64_encoded_cert_string> 1
        config:
          insecureSkipTLSVerify: "false" 2
# ...
    1
    Specify the Base64-encoded CA certificate string.
    2
    The insecureSkipTLSVerify configuration can be set to either "true" or "false". If set to "true", SSL/TLS security is disabled. If set to "false", SSL/TLS security is enabled.
4.4.6.3.2.1. Using CA certificates with the velero command aliased for Velero deployment

You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.

Prerequisites

  • You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role.

  • You must have the OpenShift CLI (oc) installed.

    1. To use an aliased Velero command, run the following command: 

      $ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'

    2. Check that the alias is working by running the following command:

      Example

      $ velero version
Client:
	Version: v1.12.1-OADP
	Git commit: -
Server:
	Version: v1.12.1-OADP

    3. To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands: 

      $ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')

$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
      $ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt

    4. To fetch the backup logs, run the following command: 

      $ velero backup logs  <backup_name>  --cacert /tmp/<your_cacert.txt>

      You can use these logs to view failures and warnings for the resources that you cannot back up.

    5. If the Velero pod restarts, the /tmp/your-cacert.txt file disappears, and you must re-create the /tmp/your-cacert.txt file by re-running the commands from the previous step.

    6. You can check if the /tmp/your-cacert.txt file still exists, in the file location where you stored it, by running the following command: 

      $ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"
/tmp/your-cacert.txt

In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.

4.4.6.4. Installing the Data Protection Application 1.2 and earlier

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.

    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.

      Note

      If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

      Note

      Velero creates a secret named velero-repo-credentials in the OADP namespace, which contains a default backup repository password. You can update the secret with your own password encoded as base64 before you run your first backup targeted to the backup repository. The value of the key to update is Data[repository-password].

      After you create your DPA, the first time that you run a backup targeted to the backup repository, Velero creates a backup repository whose secret is velero-repo-credentials, which contains either the default password or the one you replaced it with. If you update the secret password after the first backup, the new password will not match the password in velero-repo-credentials, and therefore, Velero will not be able to connect with the older backups.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
  configuration:
    velero:
      defaultPlugins:
        - aws 1
        - openshift 2
      resourceTimeout: 10m 3
    restic:
      enable: true 4
      podConfig:
        nodeSelector: <node_selector> 5
  backupLocations:
    - velero:
        config:
          profile: "default"
          region: <region_name> 6
          s3Url: <url> 7
          insecureSkipTLSVerify: "true"
          s3ForcePathStyle: "true"
        provider: aws
        default: true
        credential:
          key: cloud
          name: cloud-credentials 8
        objectStorage:
          bucket: <bucket_name> 9
          prefix: <prefix> 10
    1
    An object store plugin corresponding to your storage locations is required. For all S3 providers, the required plugin is aws. For Azure and GCP object stores, the azure or gcp plugin is required.
    2
    The openshift plugin is mandatory.
    3
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    4
    Set this value to false if you want to disable the Restic installation. Restic deploys a daemon set, which means that Restic pods run on each working node. In OADP version 1.2 and later, you can configure Restic for backups by adding spec.defaultVolumesToFsBackup: true to the Backup CR. In OADP version 1.1, add spec.defaultVolumesToRestic: true to the Backup CR.
    5
    Specify on which nodes Restic is available. By default, Restic runs on all nodes.
    6
    Specify the region, following the naming convention of the documentation of your object storage server.
    7
    Specify the URL of the S3 endpoint.
    8
    If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the backup location.
    9
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    10
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
  4. Click Create.

Verification

  1. Verify the installation by viewing the OpenShift API for Data Protection (OADP) resources by running the following command: 

    $ oc get all -n openshift-adp

4.4.6.5. Installing the Data Protection Application 1.3

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.
    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.
    Note

    If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp 1
spec:
  configuration:
    velero:
      defaultPlugins:
        - aws 2
        - openshift 3
      resourceTimeout: 10m 4
    nodeAgent: 5
      enable: true 6
      uploaderType: kopia 7
      podConfig:
        nodeSelector: <node_selector> 8
  backupLocations:
    - velero:
        config:
          profile: "default"
          region: <region_name> 9
          s3Url: <url> 10
          insecureSkipTLSVerify: "true"
          s3ForcePathStyle: "true"
        provider: aws
        default: true
        credential:
          key: cloud
          name: cloud-credentials 11
        objectStorage:
          bucket: <bucket_name> 12
          prefix: <prefix> 13
    1
    The default namespace for OADP is openshift-adp. The namespace is a variable and is configurable.
    2
    An object store plugin corresponding to your storage locations is required. For all S3 providers, the required plugin is aws. For Azure and GCP object stores, the azure or gcp plugin is required.
    3
    The openshift plugin is mandatory.
    4
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    5
    The administrative agent that routes the administrative requests to servers.
    6
    Set this value to true if you want to enable nodeAgent and perform File System Backup.
    7
    Enter kopia or restic as your uploader. You cannot change the selection after the installation. For the Built-in DataMover you must use Kopia. The nodeAgent deploys a daemon set, which means that the nodeAgent pods run on each working node. You can configure File System Backup by adding spec.defaultVolumesToFsBackup: true to the Backup CR.
    8
    Specify the nodes on which Kopia or Restic are available. By default, Kopia or Restic run on all nodes.
    9
    Specify the region, following the naming convention of the documentation of your object storage server.
    10
    Specify the URL of the S3 endpoint.
    11
    Specify the name of the Secret object that you created. If you do not specify this value, the default name, cloud-credentials, is used. If you specify a custom name, the custom name is used for the backup location.
    12
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    13
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
  4. Click Create.

Verification

  1. Verify the installation by viewing the OpenShift API for Data Protection (OADP) resources by running the following command:

  2. Verify that the DataProtectionApplication (DPA) is reconciled by running the following command: 

    $ oc get dpa dpa-sample -n openshift-adp -o jsonpath='{.status}'

    Example output

    {"conditions":[{"lastTransitionTime":"2023-10-27T01:23:57Z","message":"Reconcile complete","reason":"Complete","status":"True","type":"Reconciled"}]}

  3. Verify the type is set to Reconciled.

  4. Verify the backup storage location and confirm that the PHASE is Available by running the following command: 

    $ oc get backupStorageLocation -n openshift-adp

    Example output

    NAME           PHASE       LAST VALIDATED   AGE     DEFAULT
dpa-sample-1   Available   1s               3d16h   true

4.4.6.5.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.6.5.2. Enabling CSI in the DataProtectionApplication CR

You enable the Container Storage Interface (CSI) in the DataProtectionApplication custom resource (CR) in order to back up persistent volumes with CSI snapshots.

Prerequisites

  • The cloud provider must support CSI snapshots.

Procedure

  • Edit the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - csi 1
    1
    Add the csi default plugin.
4.4.6.5.3. Disabling the node agent in DataProtectionApplication

If you are not using Restic, Kopia, or DataMover for your backups, you can disable the nodeAgent field in the DataProtectionApplication custom resource (CR). Before you disable nodeAgent, ensure the OADP Operator is idle and not running any backups.

Procedure

  1. To disable the nodeAgent, set the enable flag to false. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: false  1
    uploaderType: kopia
# ...

    1
    Disables the node agent.

  2. To enable the nodeAgent, set the enable flag to true. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: true  1
    uploaderType: kopia
# ...

    1
    Enables the node agent.

You can set up a job to enable and disable the nodeAgent field in the DataProtectionApplication CR. For more information, see "Running tasks in pods using jobs".

Additional resources

4.4.7. Configuring the OpenShift API for Data Protection with OpenShift Data Foundation

You install the OpenShift API for Data Protection (OADP) with OpenShift Data Foundation by installing the OADP Operator and configuring a backup location and a snapshot location. Then, you install the Data Protection Application.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You can configure Multicloud Object Gateway or any AWS S3-compatible object storage as a backup location.

Important

The CloudStorage API, which automates the creation of a bucket for object storage, is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

You create a Secret for the backup location and then you install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. For details, see Using Operator Lifecycle Manager on restricted networks.

4.4.7.1. About backup and snapshot locations and their secrets

You specify backup and snapshot locations and their secrets in the DataProtectionApplication custom resource (CR).

Backup locations

You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.

Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.

Snapshot locations

If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.

If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass CR to register the CSI driver.

If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.

Secrets

If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret.

If the backup and snapshot locations use different credentials, you create two secret objects:

  • Custom Secret for the backup location, which you specify in the DataProtectionApplication CR.
  • Default Secret for the snapshot location, which is not referenced in the DataProtectionApplication CR.
Important

The Data Protection Application requires a default Secret. Otherwise, the installation will fail.

If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file.

Additional resources

4.4.7.1.1. Creating a default Secret

You create a default Secret if your backup and snapshot locations use the same credentials or if you do not require a snapshot location.

The default name of the Secret is cloud-credentials, unless your backup storage provider has a default plugin, such as aws, azure, or gcp. In that case, the default name is specified in the provider-specific OADP installation procedure.

Note

The DataProtectionApplication custom resource (CR) requires a default Secret. Otherwise, the installation will fail. If the name of the backup location Secret is not specified, the default name is used.

If you do not want to use the backup location credentials during the installation, you can create a Secret with the default name by using an empty credentials-velero file.

Prerequisites

  • Your object storage and cloud storage, if any, must use the same credentials.
  • You must configure object storage for Velero.
  • You must create a credentials-velero file for the object storage in the appropriate format.

Procedure

  • Create a Secret with the default name: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero

The Secret is referenced in the spec.backupLocations.credential block of the DataProtectionApplication CR when you install the Data Protection Application.

4.4.7.1.2. Creating secrets for different credentials

If your backup and snapshot locations use different credentials, you must create two Secret objects:

  • Backup location Secret with a custom name. The custom name is specified in the spec.backupLocations block of the DataProtectionApplication custom resource (CR).
  • Snapshot location Secret with the default name, cloud-credentials. This Secret is not specified in the DataProtectionApplication CR.

Procedure

  1. Create a credentials-velero file for the snapshot location in the appropriate format for your cloud provider.

  2. Create a Secret for the snapshot location with the default name: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero
  3. Create a credentials-velero file for the backup location in the appropriate format for your object storage.

  4. Create a Secret for the backup location with a custom name: 

    $ oc create secret generic <custom_secret> -n openshift-adp --from-file cloud=credentials-velero

  5. Add the Secret with the custom name to the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
...
  backupLocations:
    - velero:
        provider: <provider>
        default: true
        credential:
          key: cloud
          name: <custom_secret> 1
        objectStorage:
          bucket: <bucket_name>
          prefix: <prefix>
    1
    Backup location Secret with custom name.
4.4.7.2. Configuring the Data Protection Application

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.

4.4.7.2.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

Use the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.

For more details, see Configuring node agents and node labels.

4.4.7.2.1.1. Adjusting Ceph CPU and memory requirements based on collected data

The following recommendations are based on observations of performance made in the scale and performance lab. The changes are specifically related to Red Hat OpenShift Data Foundation (ODF). If working with ODF, consult the appropriate tuning guides for official recommendations.

4.4.7.2.1.1.1. CPU and memory requirement for configurations

Backup and restore operations require large amounts of CephFS PersistentVolumes (PVs). To avoid Ceph MDS pods restarting with an out-of-memory (OOM) error, the following configuration is suggested:

Configuration typesRequestMax limit

CPU

Request changed to 3

Max limit to 3

Memory

Request changed to 8 Gi

Max limit to 128 Gi

4.4.7.2.2. Enabling self-signed CA certificates

You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication custom resource (CR) manifest to prevent a certificate signed by unknown authority error.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the spec.backupLocations.velero.objectStorage.caCert parameter and spec.backupLocations.velero.config parameters of the DataProtectionApplication CR manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  backupLocations:
    - name: default
      velero:
        provider: aws
        default: true
        objectStorage:
          bucket: <bucket>
          prefix: <prefix>
          caCert: <base64_encoded_cert_string> 1
        config:
          insecureSkipTLSVerify: "false" 2
# ...
    1
    Specify the Base64-encoded CA certificate string.
    2
    The insecureSkipTLSVerify configuration can be set to either "true" or "false". If set to "true", SSL/TLS security is disabled. If set to "false", SSL/TLS security is enabled.
4.4.7.2.2.1. Using CA certificates with the velero command aliased for Velero deployment

You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.

Prerequisites

  • You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin role.

  • You must have the OpenShift CLI (oc) installed.

    1. To use an aliased Velero command, run the following command: 

      $ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'

    2. Check that the alias is working by running the following command:

      Example

      $ velero version
Client:
	Version: v1.12.1-OADP
	Git commit: -
Server:
	Version: v1.12.1-OADP

    3. To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands: 

      $ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')

$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
      $ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt

    4. To fetch the backup logs, run the following command: 

      $ velero backup logs  <backup_name>  --cacert /tmp/<your_cacert.txt>

      You can use these logs to view failures and warnings for the resources that you cannot back up.

    5. If the Velero pod restarts, the /tmp/your-cacert.txt file disappears, and you must re-create the /tmp/your-cacert.txt file by re-running the commands from the previous step.

    6. You can check if the /tmp/your-cacert.txt file still exists, in the file location where you stored it, by running the following command: 

      $ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"

In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.

4.4.7.3. Installing the Data Protection Application 1.2 and earlier

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

  • If the backup and snapshot locations use different credentials, you must create two Secrets:

    • Secret with a custom name for the backup location. You add this Secret to the DataProtectionApplication CR.

    • Secret with another custom name for the snapshot location. You add this Secret to the DataProtectionApplication CR.

      Note

      If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

      Note

      Velero creates a secret named velero-repo-credentials in the OADP namespace, which contains a default backup repository password. You can update the secret with your own password encoded as base64 before you run your first backup targeted to the backup repository. The value of the key to update is Data[repository-password].

      After you create your DPA, the first time that you run a backup targeted to the backup repository, Velero creates a backup repository whose secret is velero-repo-credentials, which contains either the default password or the one you replaced it with. If you update the secret password after the first backup, the new password will not match the password in velero-repo-credentials, and therefore, Velero will not be able to connect with the older backups.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.
  2. Under Provided APIs, click Create instance in the DataProtectionApplication box.

  3. Click YAML View and update the parameters of the DataProtectionApplication manifest: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
  namespace: openshift-adp
spec:
  configuration:
    velero:
      defaultPlugins:
        - aws 1
        - kubevirt 2
        - csi 3
        - openshift 4
      resourceTimeout: 10m 5
    restic:
      enable: true 6
      podConfig:
        nodeSelector: <node_selector> 7
  backupLocations:
    - velero:
        provider: gcp 8
        default: true
        credential:
          key: cloud
          name: <default_secret> 9
        objectStorage:
          bucket: <bucket_name> 10
          prefix: <prefix> 11
    1
    An object store plugin corresponding to your storage locations is required. For all S3 providers, the required plugin is aws. For Azure and GCP object stores, the azure or gcp plugin is required.
    2
    Optional: The kubevirt plugin is used with OpenShift Virtualization.
    3
    Specify the csi default plugin if you use CSI snapshots to back up PVs. The csi plugin uses the Velero CSI beta snapshot APIs. You do not need to configure a snapshot location.
    4
    The openshift plugin is mandatory.
    5
    Specify how many minutes to wait for several Velero resources before timeout occurs, such as Velero CRD availability, volumeSnapshot deletion, and backup repository availability. The default is 10m.
    6
    Set this value to false if you want to disable the Restic installation. Restic deploys a daemon set, which means that Restic pods run on each working node. In OADP version 1.2 and later, you can configure Restic for backups by adding spec.defaultVolumesToFsBackup: true to the Backup CR. In OADP version 1.1, add spec.defaultVolumesToRestic: true to the Backup CR.
    7
    Specify on which nodes Restic is available. By default, Restic runs on all nodes.
    8
    Specify the backup provider.
    9
    Specify the correct default name for the Secret, for example, cloud-credentials-gcp, if you use a default plugin for the backup provider. If specifying a custom name, then the custom name is used for the backup location. If you do not specify a Secret name, the default name is used.
    10
    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    11
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
  4. Click Create.

4.4.7.4.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.7.4.2. Creating an Object Bucket Claim for disaster recovery on OpenShift Data Foundation

If you use cluster storage for your Multicloud Object Gateway (MCG) bucket backupStorageLocation on OpenShift Data Foundation, create an Object Bucket Claim (OBC) using the OpenShift Web Console.

Warning

Failure to configure an Object Bucket Claim (OBC) might lead to backups not being available.

Note

Unless specified otherwise, "NooBaa" refers to the open source project that provides lightweight object storage, while "Multicloud Object Gateway (MCG)" refers to the Red Hat distribution of NooBaa.

For more information on the MCG, see Accessing the Multicloud Object Gateway with your applications.

Procedure

4.4.7.4.3. Enabling CSI in the DataProtectionApplication CR

You enable the Container Storage Interface (CSI) in the DataProtectionApplication custom resource (CR) in order to back up persistent volumes with CSI snapshots.

Prerequisites

  • The cloud provider must support CSI snapshots.

Procedure

  • Edit the DataProtectionApplication CR, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
  configuration:
    velero:
      defaultPlugins:
      - openshift
      - csi 1
    1
    Add the csi default plugin.
4.4.7.4.4. Disabling the node agent in DataProtectionApplication

If you are not using Restic, Kopia, or DataMover for your backups, you can disable the nodeAgent field in the DataProtectionApplication custom resource (CR). Before you disable nodeAgent, ensure the OADP Operator is idle and not running any backups.

Procedure

  1. To disable the nodeAgent, set the enable flag to false. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: false  1
    uploaderType: kopia
# ...

    1
    Disables the node agent.

  2. To enable the nodeAgent, set the enable flag to true. See the following example:

    Example DataProtectionApplication CR

    # ...
configuration:
  nodeAgent:
    enable: true  1
    uploaderType: kopia
# ...

    1
    Enables the node agent.

You can set up a job to enable and disable the nodeAgent field in the DataProtectionApplication CR. For more information, see "Running tasks in pods using jobs".

4.4.8. Configuring the OpenShift API for Data Protection with OpenShift Virtualization

You can install the OpenShift API for Data Protection (OADP) with OpenShift Virtualization by installing the OADP Operator and configuring a backup location. Then, you can install the Data Protection Application.

Back up and restore virtual machines by using the OpenShift API for Data Protection.

Note

OpenShift API for Data Protection with OpenShift Virtualization supports the following backup and restore storage options:

  • Container Storage Interface (CSI) backups
  • Container Storage Interface (CSI) backups with DataMover

The following storage options are excluded:

  • File system backup and restore
  • Volume snapshot backups and restores

For more information, see Backing up applications with File System Backup: Kopia or Restic.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.

4.4.8.1. Installing and configuring OADP with OpenShift Virtualization

As a cluster administrator, you install OADP by installing the OADP Operator.

The latest version of the OADP Operator installs Velero 1.14.

Prerequisites

  • Access to the cluster as a user with the cluster-admin role.

Procedure

  1. Install the OADP Operator according to the instructions for your storage provider.
  2. Install the Data Protection Application (DPA) with the kubevirt and openshift OADP plugins.

  3. Back up virtual machines by creating a Backup custom resource (CR).

    Warning

    Red Hat support is limited to only the following options:

    • CSI backups
    • CSI backups with DataMover.

You restore the Backup CR by creating a Restore CR.

Additional resources

4.4.8.2. Installing the Data Protection Application 1.3

You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication API.

Prerequisites

  • You must install the OADP Operator.
  • You must configure object storage as a backup location.
  • If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.

  • If the backup and snapshot locations use the same credentials, you must create a Secret with the default name, cloud-credentials.

    Note

    If you do not want to specify backup or snapshot locations during the installation, you can create a default Secret with an empty credentials-velero file. If there is no default Secret, the installation will fail.

Procedure

  1. Click Operators → Installed Operators and select the OADP Operator.

    Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.
    14
    Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.
  4. Click Create.

4.4.8.2.1. Configuring node agents and node labels

The DPA of OADP uses the nodeSelector field to select which nodes can run the node agent. The nodeSelector field is the simplest recommended form of node selection constraint.

Any label specified must match the labels on each node.

The correct way to run the node agent on any node you choose is for you to label the nodes with a custom label: 

$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector, which you used for labeling nodes. For example: 

configuration:
  nodeAgent:
    enable: true
    podConfig:
      nodeSelector:
        node-role.kubernetes.io/nodeAgent: ""

The following example is an anti-pattern of nodeSelector and does not work unless both labels, 'node-role.kubernetes.io/infra: ""' and 'node-role.kubernetes.io/worker: ""', are on the node: 

    configuration:
      nodeAgent:
        enable: true
        podConfig:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
            node-role.kubernetes.io/worker: ""
4.4.8.3. About incremental back up support

OADP supports incremental backups of block and Filesystem persistent volumes for both containerized, and OpenShift Virtualization workloads. The following table summarizes the support for File System Backup (FSB), Container Storage Interface (CSI), and CSI Data Mover:

Important

Red Hat only supports the combination of OADP versions 1.3.0 and later, and OpenShift Virtualization versions 4.14 and later.

OADP versions before 1.3.0 are not supported for back up and restore of OpenShift Virtualization.

4.4.9. Configuring the OpenShift API for Data Protection (OADP) with more than one Backup Storage Location

You can configure one or more backup storage locations (BSLs) in the Data Protection Application (DPA). You can also select the location to store the backup in when you create the backup. With this configuration, you can store your backups in the following ways:

  • To different regions
  • To a different storage provider

OADP supports multiple credentials for configuring more than one BSL, so that you can specify the credentials to use with any BSL.

4.4.9.1. Configuring the DPA with more than one BSL

You can configure the DPA with more than one BSL and specify the credentials provided by the cloud provider.

Prerequisites

  • You must install the OADP Operator.
  • You must create the secrets by using the credentials provided by the cloud provider.

Procedure

  1. Configure the DPA with more than one BSL. See the following example.

    Example DPA

    apiVersion: oadp.openshift.io/v1alpha1

    1
    Specify the namespace to back up.
    2
    Specify the storage location.
4.4.9.2. OADP use case for two BSLs

In this use case, you configure the DPA with two storage locations by using two cloud credentials. You back up an application with a database by using the default BSL. OADP stores the backup resources in the default BSL. You then backup the application again by using the second BSL.

Prerequisites

  • You must install the OADP Operator.
  • You must configure two backup storage locations: AWS S3 and Multicloud Object Gateway (MCG).
  • You must have an application with a database deployed on a Red Hat OpenShift cluster.

Procedure

  1. Create the first Secret for the AWS S3 storage provider with the default name by running the following command: 

    $ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=<aws_credentials_file_name> 1
    1
    Specify the name of the cloud credentials file for AWS S3.

  2. Create the second Secret for MCG with a custom name by running the following command: 

    $ oc create secret generic mcg-secret -n openshift-adp --from-file cloud=<MCG_credentials_file_name> 1
    1
    Specify the name of the cloud credentials file for MCG. Note the name of the mcg-secret custom secret.

  3. Configure the DPA with the two BSLs as shown in the following example.

4.4.10. Configuring the OpenShift API for Data Protection (OADP) with more than one Volume Snapshot Location

You can configure one or more Volume Snapshot Locations (VSLs) to store the snapshots in different cloud provider regions.

4.4.10.1. Configuring the DPA with more than one VSL

You configure the DPA with more than one VSL and specify the credentials provided by the cloud provider. Make sure that you configure the snapshot location in the same region as the persistent volumes. See the following example.

Example DPA

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
#...
snapshotLocations:
  - velero:
      config:
        profile: default
        region: <region> 1
      credential:
        key: cloud
        name: cloud-credentials
      provider: aws
  - velero:
      config:
        profile: default
        region: <region>
      credential:
        key: cloud
        name: <custom_credential> 2
      provider: aws
#...

1
Specify the region. The snapshot location must be in the same region as the persistent volumes.
2
Specify the custom credential name.

4.5. Uninstalling OADP

4.5.1. Uninstalling the OpenShift API for Data Protection

You uninstall the OpenShift API for Data Protection (OADP) by deleting the OADP Operator. See Deleting Operators from a cluster for details.

4.6. OADP backing up

4.6.1. Backing up applications

Frequent backups might consume storage on the backup storage location. Check the frequency of backups, retention time, and the amount of data of the persistent volumes (PVs) if using non-local backups, for example, S3 buckets. Because all taken backup remains until expired, also check the time to live (TTL) setting of the schedule.

You can back up applications by creating a Backup custom resource (CR). For more information, see Creating a Backup CR.

  • The Backup CR creates backup files for Kubernetes resources and internal images on S3 object storage.
  • If your cloud provider has a native snapshot API or supports CSI snapshots, the Backup CR backs up persistent volumes (PVs) by creating snapshots. For more information about working with CSI snapshots, see Backing up persistent volumes with CSI snapshots.

For more information about CSI volume snapshots, see CSI volume snapshots.

Important

The CloudStorage API, which automates the creation of a bucket for object storage, is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

Note

The CloudStorage API is a Technology Preview feature when you use a CloudStorage object and want OADP to use the CloudStorage API to automatically create an S3 bucket for use as a BackupStorageLocation.

The CloudStorage API supports manually creating a BackupStorageLocation object by specifying an existing S3 bucket. The CloudStorage API that creates an S3 bucket automatically is currently only enabled for AWS S3 storage.

PodVolumeRestore fails with a …​/.snapshot: read-only file system error

The …​/.snapshot directory is a snapshot copy directory, which is used by several NFS servers. This directory has read-only access by default, so Velero cannot restore to this directory.

Do not give Velero write access to the .snapshot directory, and disable client access to this directory.

Additional resources

Important

The OpenShift API for Data Protection (OADP) does not support backing up volume snapshots that were created by other software.

4.6.1.1. Previewing resources before running backup and restore

OADP backs up application resources based on the type, namespace, or label. This means that you can view the resources after the backup is complete. Similarly, you can view the restored objects based on the namespace, persistent volume (PV), or label after a restore operation is complete. To preview the resources in advance, you can do a dry run of the backup and restore operations.

Prerequisites

  • You have installed the OADP Operator.

Procedure

  1. To preview the resources included in the backup before running the actual backup, run the following command: 

    $ velero backup create <backup-name> --snapshot-volumes false 1
    1
    Specify the value of --snapshot-volumes parameter as false.

  2. To know more details about the backup resources, run the following command: 

    $ velero describe backup <backup_name> --details 1
    1
    Specify the name of the backup.

  3. To preview the resources included in the restore before running the actual restore, run the following command: 

    $ velero restore create --from-backup <backup-name> 1
    1
    Specify the name of the backup created to review the backup resources.
    Important

    The velero restore create command creates restore resources in the cluster. You must delete the resources created as part of the restore, after you review the resources.

  4. To know more details about the restore resources, run the following command: 

    $ velero describe restore <restore_name> --details 1
    1
    Specify the name of the restore.

You can create backup hooks to run commands before or after the backup operation. See Creating backup hooks.

You can schedule backups by creating a Schedule CR instead of a Backup CR. See Scheduling backups using Schedule CR.

4.6.1.2. Known issues

OpenShift Container Platform 4.15 enforces a pod security admission (PSA) policy that can hinder the readiness of pods during a Restic restore process. 

This issue has been resolved in the OADP 1.1.6 and OADP 1.2.2 releases, therefore it is recommended that users upgrade to these releases.

For more information, see Restic restore partially failing on OCP 4.15 due to changed PSA policy.

Additional resources

4.6.2. Creating a Backup CR

You back up Kubernetes resources, internal images, and persistent volumes (PVs) by creating a Backup custom resource (CR).

Prerequisites

  • You must install the OpenShift API for Data Protection (OADP) Operator.
  • The DataProtectionApplication CR must be in a Ready state.

  • Backup location prerequisites:

    • You must have S3 object storage configured for Velero.
    • You must have a backup location configured in the DataProtectionApplication CR.

  • Snapshot location prerequisites:

    • Your cloud provider must have a native snapshot API or support Container Storage Interface (CSI) snapshots.
    • For CSI snapshots, you must create a VolumeSnapshotClass CR to register the CSI driver.
    • You must have a volume location configured in the DataProtectionApplication CR.

Procedure

  1. Retrieve the backupStorageLocations CRs by entering the following command: 

    $ oc get backupStorageLocations -n openshift-adp

    Example output

    NAMESPACE       NAME              PHASE       LAST VALIDATED   AGE   DEFAULT
openshift-adp   velero-sample-1   Available   11s              31m

  2. Create a Backup CR, as in the following example: 

    apiVersion: velero.io/v1
kind: Backup
metadata:
  name: <backup>
  labels:
    velero.io/storage-location: default
  namespace: openshift-adp
spec:
  hooks: {}
  includedNamespaces:
  - <namespace> 1
  includedResources: [] 2
  excludedResources: [] 3
  storageLocation: <velero-sample-1> 4
  ttl: 720h0m0s
  labelSelector: 5
    matchLabels:
      app: <label_1>
      app: <label_2>
      app: <label_3>
  orLabelSelectors: 6
  - matchLabels:
      app: <label_1>
      app: <label_2>
      app: <label_3>
    1
    Specify an array of namespaces to back up.
    2
    Optional: Specify an array of resources to include in the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. If unspecified, all resources are included.
    3
    Optional: Specify an array of resources to exclude from the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified.
    4
    Specify the name of the backupStorageLocations CR.
    5
    Map of {key,value} pairs of backup resources that have all the specified labels.
    6
    Map of {key,value} pairs of backup resources that have one or more of the specified labels.

  3. Verify that the status of the Backup CR is Completed: 

    $ oc get backup -n openshift-adp <backup> -o jsonpath='{.status.phase}'

4.6.3. Backing up persistent volumes with CSI snapshots

You back up persistent volumes with Container Storage Interface (CSI) snapshots by editing the VolumeSnapshotClass custom resource (CR) of the cloud storage before you create the Backup CR, see CSI volume snapshots.

For more information, see Creating a Backup CR.

Prerequisites

  • The cloud provider must support CSI snapshots.
  • You must enable CSI in the DataProtectionApplication CR.

Procedure

  • Add the metadata.labels.velero.io/csi-volumesnapshot-class: "true" key-value pair to the VolumeSnapshotClass CR:

    Example configuration file

    apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshotClass
metadata:
  name: <volume_snapshot_class_name>
  labels:
    velero.io/csi-volumesnapshot-class: "true" 1
  annotations:
    snapshot.storage.kubernetes.io/is-default-class: true 2
driver: <csi_driver>
deletionPolicy: <deletion_policy_type> 3

    1
    Must be set to true.
    2
    Must be set to true.
    3
    OADP supports the Retain and Delete deletion policy types for CSI and Data Mover backup and restore. For the OADP 1.2 Data Mover, set the deletion policy type to Retain.

Next steps

  • You can now create a Backup CR.

4.6.4. Backing up applications with File System Backup: Kopia or Restic

You can use OADP to back up and restore Kubernetes volumes attached to pods from the file system of the volumes. This process is called File System Backup (FSB) or Pod Volume Backup (PVB). It is accomplished by using modules from the open source backup tools Restic or Kopia.

If your cloud provider does not support snapshots or if your applications are on NFS data volumes, you can create backups by using FSB.

Note

Restic is installed by the OADP Operator by default. If you prefer, you can install Kopia instead.

FSB integration with OADP provides a solution for backing up and restoring almost any type of Kubernetes volumes. This integration is an additional capability of OADP and is not a replacement for existing functionality.

You back up Kubernetes resources, internal images, and persistent volumes with Kopia or Restic by editing the Backup custom resource (CR).

You do not need to specify a snapshot location in the DataProtectionApplication CR.

Note

In OADP version 1.3 and later, you can use either Kopia or Restic for backing up applications.

For the Built-in DataMover, you must use Kopia.

In OADP version 1.2 and earlier, you can only use Restic for backing up applications.

Important

FSB does not support backing up hostPath volumes. For more information, see FSB limitations.

PodVolumeRestore fails with a …​/.snapshot: read-only file system error

The …​/.snapshot directory is a snapshot copy directory, which is used by several NFS servers. This directory has read-only access by default, so Velero cannot restore to this directory.

Do not give Velero write access to the .snapshot directory, and disable client access to this directory.

Additional resources

Prerequisites

  • You must install the OpenShift API for Data Protection (OADP) Operator.
  • You must not disable the default nodeAgent installation by setting spec.configuration.nodeAgent.enable to false in the DataProtectionApplication CR.
  • You must select Kopia or Restic as the uploader by setting spec.configuration.nodeAgent.uploaderType to kopia or restic in the DataProtectionApplication CR.
  • The DataProtectionApplication CR must be in a Ready state.

Procedure

  • Create the Backup CR, as in the following example: 

    apiVersion: velero.io/v1
kind: Backup
metadata:
  name: <backup>
  labels:
    velero.io/storage-location: default
  namespace: openshift-adp
spec:
  defaultVolumesToFsBackup: true 1
...
    1
    In OADP version 1.2 and later, add the defaultVolumesToFsBackup: true setting within the spec block. In OADP version 1.1, add defaultVolumesToRestic: true.

4.6.5. Creating backup hooks

When performing a backup, it is possible to specify one or more commands to execute in a container within a pod, based on the pod being backed up.

The commands can be configured to performed before any custom action processing (Pre hooks), or after all custom actions have been completed and any additional items specified by the custom action have been backed up (Post hooks).

You create backup hooks to run commands in a container in a pod by editing the Backup custom resource (CR).

Procedure

  • Add a hook to the spec.hooks block of the Backup CR, as in the following example: 

    apiVersion: velero.io/v1
kind: Backup
metadata:
  name: <backup>
  namespace: openshift-adp
spec:
  hooks:
    resources:
      - name: <hook_name>
        includedNamespaces:
        - <namespace> 1
        excludedNamespaces: 2
        - <namespace>
        includedResources: []
        - pods 3
        excludedResources: [] 4
        labelSelector: 5
          matchLabels:
            app: velero
            component: server
        pre: 6
          - exec:
              container: <container> 7
              command:
              - /bin/uname 8
              - -a
              onError: Fail 9
              timeout: 30s 10
        post: 11
...
    1
    Optional: You can specify namespaces to which the hook applies. If this value is not specified, the hook applies to all namespaces.
    2
    Optional: You can specify namespaces to which the hook does not apply.
    3
    Currently, pods are the only supported resource that hooks can apply to.
    4
    Optional: You can specify resources to which the hook does not apply.
    5
    Optional: This hook only applies to objects matching the label. If this value is not specified, the hook applies to all objects.
    6
    Array of hooks to run before the backup.
    7
    Optional: If the container is not specified, the command runs in the first container in the pod.
    8
    This is the entry point for the init container being added.
    9
    Allowed values for error handling are Fail and Continue. The default is Fail.
    10
    Optional: How long to wait for the commands to run. The default is 30s.
    11
    This block defines an array of hooks to run after the backup, with the same parameters as the pre-backup hooks.

4.6.6. Scheduling backups using Schedule CR

The schedule operation allows you to create a backup of your data at a particular time, specified by a Cron expression.

You schedule backups by creating a Schedule custom resource (CR) instead of a Backup CR.

Warning

Leave enough time in your backup schedule for a backup to finish before another backup is created.

For example, if a backup of a namespace typically takes 10 minutes, do not schedule backups more frequently than every 15 minutes.

Prerequisites

  • You must install the OpenShift API for Data Protection (OADP) Operator.
  • The DataProtectionApplication CR must be in a Ready state.

Procedure

  1. Retrieve the backupStorageLocations CRs: 

    $ oc get backupStorageLocations -n openshift-adp

    Example output

    NAMESPACE       NAME              PHASE       LAST VALIDATED   AGE   DEFAULT
openshift-adp   velero-sample-1   Available   11s              31m

  2. Create a Schedule CR, as in the following example: 

    $ cat << EOF | oc apply -f -
apiVersion: velero.io/v1
kind: Schedule
metadata:
  name: <schedule>
  namespace: openshift-adp
spec:
  schedule: 0 7 * * * 1
  template:
    hooks: {}
    includedNamespaces:
    - <namespace> 2
    storageLocation: <velero-sample-1> 3
    defaultVolumesToFsBackup: true 4
    ttl: 720h0m0s
EOF
1
cron expression to schedule the backup, for example, 0 7 * * * to perform a backup every day at 7:00.
Note

To schedule a backup at specific intervals, enter the <duration_in_minutes> in the following format: 

  schedule: "*/10 * * * *"

Enter the minutes value between quotation marks (" ").

2
Array of namespaces to back up.
3
Name of the backupStorageLocations CR.
4
Optional: In OADP version 1.2 and later, add the defaultVolumesToFsBackup: true key-value pair to your configuration when performing backups of volumes with Restic. In OADP version 1.1, add the defaultVolumesToRestic: true key-value pair when you back up volumes with Restic.

  1. Verify that the status of the Schedule CR is Completed after the scheduled backup runs: 

    $ oc get schedule -n openshift-adp <schedule> -o jsonpath='{.status.phase}'

4.6.7. Deleting backups

You can remove backup files by deleting the Backup custom resource (CR).

Warning

After you delete the Backup CR and the associated object storage data, you cannot recover the deleted data.

Prerequisites

  • You created a Backup CR.
  • You know the name of the Backup CR and the namespace that contains it.
  • You downloaded the Velero CLI tool.
  • You can access the Velero binary in your cluster.

Procedure

  • Choose one of the following actions to delete the Backup CR:

    • To delete the Backup CR and keep the associated object storage data, run the following command: 

      $ oc delete backup <backup_CR_name> -n <velero_namespace>

    • To delete the Backup CR and delete the associated object storage data, run the following command: 

      $ velero backup delete <backup_CR_name> -n <velero_namespace>

      Where:

      <backup_CR_name>
      The name of the Backup custom resource.
      <velero_namespace>
      The namespace that contains the Backup custom resource.

4.6.8. About Kopia

Kopia is a fast and secure open-source backup and restore tool that allows you to create encrypted snapshots of your data and save the snapshots to remote or cloud storage of your choice.

Kopia supports network and local storage locations, and many cloud or remote storage locations, including:

  • Amazon S3 and any cloud storage that is compatible with S3
  • Azure Blob Storage
  • Google Cloud Storage platform

Kopia uses content-addressable storage for snapshots:

  • Snapshots are always incremental; data that is already included in previous snapshots is not re-uploaded to the repository. A file is only uploaded to the repository again if it is modified.
  • Stored data is deduplicated; if multiple copies of the same file exist, only one of them is stored.
  • If files are moved or renamed, Kopia can recognize that they have the same content and does not upload them again.
4.6.8.1. OADP integration with Kopia

OADP 1.3 supports Kopia as the backup mechanism for pod volume backup in addition to Restic. You must choose one or the other at installation by setting the uploaderType field in the DataProtectionApplication custom resource (CR). The possible values are restic or kopia. If you do not specify an uploaderType, OADP 1.3 defaults to using Kopia as the backup mechanism. The data is written to and read from a unified repository.

The following example shows a DataProtectionApplication CR configured for using Kopia: 

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: dpa-sample
spec:
  configuration:
    nodeAgent:
      enable: true
      uploaderType: kopia
# ...

4.7. OADP restoring

4.7.1. Restoring applications

You restore application backups by creating a Restore custom resource (CR). See Creating a Restore CR.

You can create restore hooks to run commands in a container in a pod by editing the Restore CR. See Creating restore hooks.

4.7.1.1. Previewing resources before running backup and restore

OADP backs up application resources based on the type, namespace, or label. This means that you can view the resources after the backup is complete. Similarly, you can view the restored objects based on the namespace, persistent volume (PV), or label after a restore operation is complete. To preview the resources in advance, you can do a dry run of the backup and restore operations.

Prerequisites

  • You have installed the OADP Operator.

Procedure

  1. To preview the resources included in the backup before running the actual backup, run the following command: 

    $ velero backup create <backup-name> --snapshot-volumes false 1
    1
    Specify the value of --snapshot-volumes parameter as false.

  2. To know more details about the backup resources, run the following command: 

    $ velero describe backup <backup_name> --details 1
    1
    Specify the name of the backup.

  3. To preview the resources included in the restore before running the actual restore, run the following command: 

    $ velero restore create --from-backup <backup-name> 1
    1
    Specify the name of the backup created to review the backup resources.
    Important

    The velero restore create command creates restore resources in the cluster. You must delete the resources created as part of the restore, after you review the resources.

  4. To know more details about the restore resources, run the following command: 

    $ velero describe restore <restore_name> --details 1
    1
    Specify the name of the restore.
4.7.1.2. Creating a Restore CR

You restore a Backup custom resource (CR) by creating a Restore CR.

Prerequisites

  • You must install the OpenShift API for Data Protection (OADP) Operator.
  • The DataProtectionApplication CR must be in a Ready state.
  • You must have a Velero Backup CR.
  • The persistent volume (PV) capacity must match the requested size at backup time. Adjust the requested size if needed.

Procedure

  1. Create a Restore CR, as in the following example: 

    apiVersion: velero.io/v1
kind: Restore
metadata:
  name: <restore>
  namespace: openshift-adp
spec:
  backupName: <backup> 1
  includedResources: [] 2
  excludedResources:
  - nodes
  - events
  - events.events.k8s.io
  - backups.velero.io
  - restores.velero.io
  - resticrepositories.velero.io
  restorePVs: true 3
    1
    Name of the Backup CR.
    2
    Optional: Specify an array of resources to include in the restore process. Resources might be shortcuts (for example, po for pods) or fully-qualified. If unspecified, all resources are included.
    3
    Optional: The restorePVs parameter can be set to false to turn off restore of PersistentVolumes from VolumeSnapshot of Container Storage Interface (CSI) snapshots or from native snapshots when VolumeSnapshotLocation is configured.

  2. Verify that the status of the Restore CR is Completed by entering the following command: 

    $ oc get restore -n openshift-adp <restore> -o jsonpath='{.status.phase}'

  3. Verify that the backup resources have been restored by entering the following command: 

    $ oc get all -n <namespace> 1
    1
    Namespace that you backed up.

  4. If you restore DeploymentConfig with volumes or if you use post-restore hooks, run the dc-post-restore.sh cleanup script by entering the following command: 

    $ bash dc-restic-post-restore.sh -> dc-post-restore.sh
    Note

    During the restore process, the OADP Velero plug-ins scale down the DeploymentConfig objects and restore the pods as standalone pods. This is done to prevent the cluster from deleting the restored DeploymentConfig pods immediately on restore and to allow the restore and post-restore hooks to complete their actions on the restored pods. The cleanup script shown below removes these disconnected pods and scales any DeploymentConfig objects back up to the appropriate number of replicas.

    Example 4.1. dc-restic-post-restore.sh → dc-post-restore.sh cleanup script

    #!/bin/bash
set -e

# if sha256sum exists, use it to check the integrity of the file
if command -v sha256sum >/dev/null 2>&1; then
  CHECKSUM_CMD="sha256sum"
else
  CHECKSUM_CMD="shasum -a 256"
fi

label_name () {
    if [ "${#1}" -le "63" ]; then
	echo $1
	return
    fi
    sha=$(echo -n $1|$CHECKSUM_CMD)
    echo "${1:0:57}${sha:0:6}"
}

if [[ $# -ne 1 ]]; then
    echo "usage: ${BASH_SOURCE} restore-name"
    exit 1
fi

echo "restore: $1"

label=$(label_name $1)
echo "label:   $label"

echo Deleting disconnected restore pods
oc delete pods --all-namespaces -l oadp.openshift.io/disconnected-from-dc=$label

for dc in $(oc get dc --all-namespaces -l oadp.openshift.io/replicas-modified=$label -o jsonpath='{range .items[*]}{.metadata.namespace}{","}{.metadata.name}{","}{.metadata.annotations.oadp\.openshift\.io/original-replicas}{","}{.metadata.annotations.oadp\.openshift\.io/original-paused}{"\n"}')
do
    IFS=',' read -ra dc_arr <<< "$dc"
    if [ ${#dc_arr[0]} -gt 0 ]; then
	echo Found deployment ${dc_arr[0]}/${dc_arr[1]}, setting replicas: ${dc_arr[2]}, paused: ${dc_arr[3]}
	cat <<EOF | oc patch dc  -n ${dc_arr[0]} ${dc_arr[1]} --patch-file /dev/stdin
spec:
  replicas: ${dc_arr[2]}
  paused: ${dc_arr[3]}
EOF
    fi
done
4.7.1.3. Creating restore hooks

You create restore hooks to run commands in a container in a pod by editing the Restore custom resource (CR).

You can create two types of restore hooks:

  • An init hook adds an init container to a pod to perform setup tasks before the application container starts.

    If you restore a Restic backup, the restic-wait init container is added before the restore hook init container.

  • An exec hook runs commands or scripts in a container of a restored pod.

Procedure

  • Add a hook to the spec.hooks block of the Restore CR, as in the following example: 

    apiVersion: velero.io/v1
kind: Restore
metadata:
  name: <restore>
  namespace: openshift-adp
spec:
  hooks:
    resources:
      - name: <hook_name>
        includedNamespaces:
        - <namespace> 1
        excludedNamespaces:
        - <namespace>
        includedResources:
        - pods 2
        excludedResources: []
        labelSelector: 3
          matchLabels:
            app: velero
            component: server
        postHooks:
        - init:
            initContainers:
            - name: restore-hook-init
              image: alpine:latest
              volumeMounts:
              - mountPath: /restores/pvc1-vm
                name: pvc1-vm
              command:
              - /bin/ash
              - -c
            timeout: 4
        - exec:
            container: <container> 5
            command:
            - /bin/bash 6
            - -c
            - "psql < /backup/backup.sql"
            waitTimeout: 5m 7
            execTimeout: 1m 8
            onError: Continue 9
    1
    Optional: Array of namespaces to which the hook applies. If this value is not specified, the hook applies to all namespaces.
    2
    Currently, pods are the only supported resource that hooks can apply to.
    3
    Optional: This hook only applies to objects matching the label selector.
    4
    Optional: Timeout specifies the maximum length of time Velero waits for initContainers to complete.
    5
    Optional: If the container is not specified, the command runs in the first container in the pod.
    6
    This is the entrypoint for the init container being added.
    7
    Optional: How long to wait for a container to become ready. This should be long enough for the container to start and for any preceding hooks in the same container to complete. If not set, the restore process waits indefinitely.
    8
    Optional: How long to wait for the commands to run. The default is 30s.
    9
    Allowed values for error handling are Fail and Continue:
    • Continue: Only command failures are logged.
    • Fail: No more restore hooks run in any container in any pod. The status of the Restore CR will be PartiallyFailed.
Important

During a File System Backup (FSB) restore operation, a Deployment resource referencing an ImageStream is not restored properly. The restored pod that runs the FSB, and the postHook is terminated prematurely.

This happens because, during the restore operation, OpenShift controller updates the spec.template.spec.containers[0].image field in the Deployment resource with an updated ImageStreamTag hash. The update triggers the rollout of a new pod, terminating the pod on which velero runs the FSB and the post restore hook. For more information about image stream trigger, see "Triggering updates on image stream changes".

The workaround for this behavior is a two-step restore process:

  1. First, perform a restore excluding the Deployment resources, for example: 

    $ velero restore create <RESTORE_NAME> \
  --from-backup <BACKUP_NAME> \
  --exclude-resources=deployment.apps

  2. After the first restore is successful, perform a second restore by including these resources, for example: 

    $ velero restore create <RESTORE_NAME> \
  --from-backup <BACKUP_NAME> \
  --include-resources=deployment.apps

Additional resources

4.8. OADP and ROSA

4.8.1. Backing up applications on ROSA clusters using OADP

You can use OpenShift API for Data Protection (OADP) with Red Hat OpenShift Service on AWS (ROSA) clusters to back up and restore application data.

ROSA is a fully-managed, turnkey application platform that allows you to deliver value to your customers by building and deploying applications.

ROSA provides seamless integration with a wide range of Amazon Web Services (AWS) compute, database, analytics, machine learning, networking, mobile, and other services to speed up the building and delivery of differentiating experiences to your customers.

You can subscribe to the service directly from your AWS account.

After you create your clusters, you can operate your clusters with the OpenShift Container Platform web console or through Red Hat OpenShift Cluster Manager. You can also use ROSA with OpenShift APIs and command-line interface (CLI) tools.

For additional information about ROSA installation, see Installing Red Hat OpenShift Service on AWS (ROSA) interactive walkthrough.

Before installing OpenShift API for Data Protection (OADP), you must set up role and policy credentials for OADP so that it can use the Amazon Web Services API.

This process is performed in the following two stages:

  1. Prepare AWS credentials
  2. Install the OADP Operator and give it an IAM role
4.8.1.1. Preparing AWS credentials for OADP

An Amazon Web Services account must be prepared and configured to accept an OpenShift API for Data Protection (OADP) installation.

Procedure

  1. Create the following environment variables by running the following commands:

    Important

    Change the cluster name to match your ROSA cluster, and ensure you are logged into the cluster as an administrator. Ensure that all fields are outputted correctly before continuing. 

    $ export CLUSTER_NAME=my-cluster 1
  export ROSA_CLUSTER_ID=$(rosa describe cluster -c ${CLUSTER_NAME} --output json | jq -r .id)
  export REGION=$(rosa describe cluster -c ${CLUSTER_NAME} --output json | jq -r .region.id)
  export OIDC_ENDPOINT=$(oc get authentication.config.openshift.io cluster -o jsonpath='{.spec.serviceAccountIssuer}' | sed 's|^https://||')
  export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
  export CLUSTER_VERSION=$(rosa describe cluster -c ${CLUSTER_NAME} -o json | jq -r .version.raw_id | cut -f -2 -d '.')
  export ROLE_NAME="${CLUSTER_NAME}-openshift-oadp-aws-cloud-credentials"
  export SCRATCH="/tmp/${CLUSTER_NAME}/oadp"
  mkdir -p ${SCRATCH}
  echo "Cluster ID: ${ROSA_CLUSTER_ID}, Region: ${REGION}, OIDC Endpoint:
  ${OIDC_ENDPOINT}, AWS Account ID: ${AWS_ACCOUNT_ID}"
    1
    Replace my-cluster with your ROSA cluster name.

  2. On the AWS account, create an IAM policy to allow access to AWS S3:

    1. Check to see if the policy exists by running the following command: 

      $ POLICY_ARN=$(aws iam list-policies --query "Policies[?PolicyName=='RosaOadpVer1'].{ARN:Arn}" --output text) 1
      1
      Replace RosaOadp with your policy name.

    2. Enter the following command to create the policy JSON file and then create the policy in ROSA:

      Note

      If the policy ARN is not found, the command creates the policy. If the policy ARN already exists, the if statement intentionally skips the policy creation. 

      $ if [[ -z "${POLICY_ARN}" ]]; then
  cat << EOF > ${SCRATCH}/policy.json 1

      SCRATCH is a name for a temporary directory created for the environment variables.

    3. View the policy ARN by running the following command: 

      $ echo ${POLICY_ARN}

  3. Create an IAM role trust policy for the cluster:

    1. Create the trust policy file by running the following command: 

      $ cat <<EOF > ${SCRATCH}/trust-policy.json
  {
      "Version":2012-10-17",
      "Statement": [{
        "Effect": "Allow",

          }
        }
      }]
  }
EOF

    2. Create the role by running the following command: 

      $ ROLE_ARN=$(aws iam create-role --role-name \
  "${ROLE_NAME}" \
  --assume-role-policy-document file://${SCRATCH}/trust-policy.json \
--tags Key=rosa_cluster_id,Value=${ROSA_CLUSTER_ID} Key=rosa_openshift_version,Value=${CLUSTER_VERSION} Key=rosa_role_prefix,Value=ManagedOpenShift Key=operator_namespace,Value=openshift-adp Key=operator_name,Value=openshift-oadp \
   --query Role.Arn --output text)

    3. View the role ARN by running the following command: 

      $ echo ${ROLE_ARN}

  4. Attach the IAM policy to the IAM role by running the following command: 

    $ aws iam attach-role-policy --role-name "${ROLE_NAME}" \
  --policy-arn ${POLICY_ARN}
4.8.1.2. Installing the OADP Operator and providing the IAM role

AWS Security Token Service (AWS STS) is a global web service that provides short-term credentials for IAM or federated users. OpenShift Container Platform (ROSA) with STS is the recommended credential mode for ROSA clusters. This document describes how to install OpenShift API for Data Protection (OADP) on ROSA with AWS STS.

Important

Restic and Kopia are not supported in the OADP on ROSA with AWS STS environment. Verify that the Restic and Kopia node agent is disabled. For backing up volumes, OADP on ROSA with AWS STS supports only native snapshots and Container Storage Interface (CSI) snapshots.

In an Amazon ROSA cluster that uses STS authentication, restoring backed-up data in a different AWS region is not supported.

The Data Mover feature is not currently supported in ROSA clusters. You can use native AWS S3 tools for moving data.

Prerequisites

  • An OpenShift Container Platform ROSA cluster with the required access and tokens. For instructions, see the previous procedure Preparing AWS credentials for OADP. If you plan to use two different clusters for backing up and restoring, you must prepare AWS credentials, including ROLE_ARN, for each cluster.

Procedure

  1. Create an OpenShift Container Platform secret from your AWS token file by entering the following commands:

    1. Create the credentials file: 

      $ cat <<EOF > ${SCRATCH}/credentials
  [default]
  role_arn = ${ROLE_ARN}
  web_identity_token_file = /var/run/secrets/openshift/serviceaccount/token
EOF

    2. Create a namespace for OADP: 

      $ oc create namespace openshift-adp

    3. Create the OpenShift Container Platform secret: 

      $ oc -n openshift-adp create secret generic cloud-credentials \
  --from-file=${SCRATCH}/credentials
      Note

      In OpenShift Container Platform versions 4.14 and later, the OADP Operator supports a new standardized STS workflow through the Operator Lifecycle Manager (OLM) and Cloud Credentials Operator (CCO). In this workflow, you do not need to create the above secret, you only need to supply the role ARN during the installation of OLM-managed operators using the OpenShift Container Platform web console, for more information see Installing from OperatorHub using the web console.

      The preceding secret is created automatically by CCO.

  2. Install the OADP Operator:

    1. In the OpenShift Container Platform web console, browse to Operators → OperatorHub.
    2. Search for the OADP Operator.
    3. In the role_ARN field, paste the role_arn that you created previously and click Install.

  3. Create AWS cloud storage using your AWS credentials by entering the following command: 

    $ cat << EOF | oc create -f -
  apiVersion: oadp.openshift.io/v1alpha1
  kind: CloudStorage
  metadata:
    name: ${CLUSTER_NAME}-oadp
    namespace: openshift-adp
  spec:
    creationSecret:
      key: credentials
      name: cloud-credentials
    enableSharedConfig: true
    name: ${CLUSTER_NAME}-oadp
    provider: aws
    region: $REGION
EOF

  4. Check your application’s storage default storage class by entering the following command: 

    $ oc get pvc -n <namespace>

    Example output

    NAME     STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
applog   Bound    pvc-351791ae-b6ab-4e8b-88a4-30f73caf5ef8   1Gi        RWO            gp3-csi        4d19h
mysql    Bound    pvc-16b8e009-a20a-4379-accc-bc81fedd0621   1Gi        RWO            gp3-csi        4d19h

  5. Get the storage class by running the following command: 

    $ oc get storageclass

    Example output

    NAME                PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
gp2                 kubernetes.io/aws-ebs   Delete          WaitForFirstConsumer   true                   4d21h
gp2-csi             ebs.csi.aws.com         Delete          WaitForFirstConsumer   true                   4d21h
gp3                 ebs.csi.aws.com         Delete          WaitForFirstConsumer   true                   4d21h
gp3-csi (default)   ebs.csi.aws.com         Delete          WaitForFirstConsumer   true                   4d21h

    Note

    The following storage classes will work:

    • gp3-csi
    • gp2-csi
    • gp3
    • gp2

    If the application or applications that are being backed up are all using persistent volumes (PVs) with Container Storage Interface (CSI), it is advisable to include the CSI plugin in the OADP DPA configuration.

  6. Create the DataProtectionApplication resource to configure the connection to the storage where the backups and volume snapshots are stored:

    1. If you are using only CSI volumes, deploy a Data Protection Application by entering the following command: 

      $ cat << EOF | oc create -f -
  apiVersion: oadp.openshift.io/v1alpha1
  kind: DataProtectionApplication
  metadata:
    name: ${CLUSTER_NAME}-dpa
    namespace: openshift-adp
  spec:
    backupImages: true 1
    features:
      dataMover:
        enable: false
    backupLocations:
    - bucket:
        cloudStorageRef:
          name: ${CLUSTER_NAME}-oadp
        credential:
          key: credentials
          name: cloud-credentials
        prefix: velero
        default: true
        config:
          region: ${REGION}
    configuration:
      velero:
        defaultPlugins:
        - openshift
        - aws
        - csi
      restic:
        enable: false
EOF
      1
      ROSA supports internal image backup. Set this field to false if you do not want to use image backup.

  1. If you are using CSI or non-CSI volumes, deploy a Data Protection Application by entering the following command: 

    $ cat << EOF | oc create -f -
  apiVersion: oadp.openshift.io/v1alpha1
  kind: DataProtectionApplication
  metadata:
    name: ${CLUSTER_NAME}-dpa
    namespace: openshift-adp
  spec:
    backupImages: true 1
    features:
      dataMover:
         enable: false
    backupLocations:
    - bucket:
        cloudStorageRef:
          name: ${CLUSTER_NAME}-oadp
        credential:
          key: credentials
          name: cloud-credentials
        prefix: velero
        default: true
        config:
          region: ${REGION}
    configuration:
      velero:
        defaultPlugins:
        - openshift
        - aws
      nodeAgent: 2
        enable: false
        uploaderType: restic
    snapshotLocations:
      - velero:
          config:
            credentialsFile: /tmp/credentials/openshift-adp/cloud-credentials-credentials 3
            enableSharedConfig: "true" 4
            profile: default 5
            region: ${REGION} 6
          provider: aws
EOF
    1
    ROSA supports internal image backup. Set this field to false if you do not want to use image backup.
    2
    See the important note regarding the nodeAgent attribute.
    3
    The credentialsFile field is the mounted location of the bucket credential on the pod.
    4
    The enableSharedConfig field allows the snapshotLocations to share or reuse the credential defined for the bucket.
    5
    Use the profile name set in the AWS credentials file.
    6
    Specify region as your AWS region. This must be the same as the cluster region.

    You are now ready to back up and restore OpenShift Container Platform applications, as described in Backing up applications.

Important

The enable parameter of restic is set to false in this configuration, because OADP does not support Restic in ROSA environments.

If you use OADP 1.2, replace this configuration: 

nodeAgent:
  enable: false
  uploaderType: restic

with the following configuration: 

restic:
  enable: false

If you want to use two different clusters for backing up and restoring, the two clusters must have the same AWS S3 storage names in both the cloud storage CR and the OADP DataProtectionApplication configuration.

4.8.1.3.2. Cleaning up a cluster after a backup with OADP and ROSA STS

If you need to uninstall the OpenShift API for Data Protection (OADP) Operator together with the backups and the S3 bucket from this example, follow these instructions.

Procedure

  1. Delete the workload by running the following command: 

    $ oc delete ns hello-world

  2. Delete the Data Protection Application (DPA) by running the following command: 

    $ oc -n openshift-adp delete dpa ${CLUSTER_NAME}-dpa

  3. Delete the cloud storage by running the following command: 

    $ oc -n openshift-adp delete cloudstorage ${CLUSTER_NAME}-oadp
    Warning

    If this command hangs, you might need to delete the finalizer by running the following command: 

    $ oc -n openshift-adp patch cloudstorage ${CLUSTER_NAME}-oadp -p '{"metadata":{"finalizers":null}}' --type=merge

  4. If the Operator is no longer required, remove it by running the following command: 

    $ oc -n openshift-adp delete subscription oadp-operator

  5. Remove the namespace from the Operator: 

    $ oc delete ns openshift-adp

  6. If the backup and restore resources are no longer required, remove them from the cluster by running the following command: 

    $ oc delete backup hello-world

  7. To delete backup, restore and remote objects in AWS S3 run the following command: 

    $ velero backup delete hello-world

  8. If you no longer need the Custom Resource Definitions (CRD), remove them from the cluster by running the following command: 

    $ for CRD in `oc get crds | grep velero | awk '{print $1}'`; do oc delete crd $CRD; done

  9. Delete the AWS S3 bucket by running the following commands: 

    $ aws s3 rm s3://${CLUSTER_NAME}-oadp --recursive
    $ aws s3api delete-bucket --bucket ${CLUSTER_NAME}-oadp

  10. Detach the policy from the role by running the following command: 

    $ aws iam detach-role-policy --role-name "${ROLE_NAME}"  --policy-arn "${POLICY_ARN}"

  11. Delete the role by running the following command: 

    $ aws iam delete-role --role-name "${ROLE_NAME}"

4.9. OADP and AWS STS

4.9.1. Backing up applications on AWS STS using OADP

You install the OpenShift API for Data Protection (OADP) with Amazon Web Services (AWS) by installing the OADP Operator. The Operator installs Velero 1.14.

Note

Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator.

You configure AWS for Velero, create a default Secret, and then install the Data Protection Application. For more details, see Installing the OADP Operator.

To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.

You can install OADP on an AWS Security Token Service (STS) (AWS STS) cluster manually. Amazon AWS provides AWS STS as a web service that enables you to request temporary, limited-privilege credentials for users. You use STS to provide trusted users with temporary access to resources via API calls, your AWS console, or the AWS command line interface (CLI).

Before installing OpenShift API for Data Protection (OADP), you must set up role and policy credentials for OADP so that it can use the Amazon Web Services API.

This process is performed in the following two stages:

  1. Prepare AWS credentials.
  2. Install the OADP Operator and give it an IAM role.
4.9.1.1. Preparing AWS STS credentials for OADP

An Amazon Web Services account must be prepared and configured to accept an OpenShift API for Data Protection (OADP) installation. Prepare the AWS credentials by using the following procedure.

Procedure

  1. Define the cluster_name environment variable by running the following command: 

    $ export CLUSTER_NAME= <AWS_cluster_name> 1
    1
    The variable can be set to any value.

  2. Retrieve all of the details of the cluster such as the AWS_ACCOUNT_ID, OIDC_ENDPOINT by running the following command: 

    $ export CLUSTER_VERSION=$(oc get clusterversion version -o jsonpath='{.status.desired.version}{"\n"}')

export AWS_CLUSTER_ID=$(oc get clusterversion version -o jsonpath='{.spec.clusterID}{"\n"}')

export OIDC_ENDPOINT=$(oc get authentication.config.openshift.io cluster -o jsonpath='{.spec.serviceAccountIssuer}' | sed 's|^https://||')

export REGION=$(oc get infrastructures cluster -o jsonpath='{.status.platformStatus.aws.region}' --allow-missing-template-keys=false || echo us-east-2)

export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)

export ROLE_NAME="${CLUSTER_NAME}-openshift-oadp-aws-cloud-credentials"

  3. Create a temporary directory to store all of the files by running the following command: 

    $ export SCRATCH="/tmp/${CLUSTER_NAME}/oadp"
mkdir -p ${SCRATCH}

  4. Display all of the gathered details by running the following command: 

    $ echo "Cluster ID: ${AWS_CLUSTER_ID}, Region: ${REGION}, OIDC Endpoint:
${OIDC_ENDPOINT}, AWS Account ID: ${AWS_ACCOUNT_ID}"

  5. On the AWS account, create an IAM policy to allow access to AWS S3:

    1. Check to see if the policy exists by running the following commands: 

      $ export POLICY_NAME="OadpVer1" 1
      1
      The variable can be set to any value. 
      $ POLICY_ARN=$(aws iam list-policies --query "Policies[?PolicyName=='$POLICY_NAME'].{ARN:Arn}" --output text)

    2. Enter the following command to create the policy JSON file and then create the policy:

      Note

      If the policy ARN is not found, the command creates the policy. If the policy ARN already exists, the if statement intentionally skips the policy creation. 

      $ if [[ -z "${POLICY_ARN}" ]]; then
cat << EOF > ${SCRATCH}/policy.json

      1
      SCRATCH is a name for a temporary directory created for storing the files.

    3. View the policy ARN by running the following command: 

      $ echo ${POLICY_ARN}

  6. Create an IAM role trust policy for the cluster:

    1. Create the trust policy file by running the following command: 

      $ cat <<EOF > ${SCRATCH}/trust-policy.json
{
    "Version": "2012-10-17",
    "Statement": [{
      "Effect": "Allow",

            "system:serviceaccount:openshift-adp:velero"]
        }
      }
    }]
}
EOF

    2. Create an IAM role trust policy for the cluster by running the following command: 

      $ ROLE_ARN=$(aws iam create-role --role-name \
  "${ROLE_NAME}" \
  --assume-role-policy-document file://${SCRATCH}/trust-policy.json \
  --tags Key=cluster_id,Value=${AWS_CLUSTER_ID}  Key=openshift_version,Value=${CLUSTER_VERSION} Key=operator_namespace,Value=openshift-adp Key=operator_name,Value=oadp --query Role.Arn --output text)

    3. View the role ARN by running the following command: 

      $ echo ${ROLE_ARN}

  7. Attach the IAM policy to the IAM role by running the following command: 

    $ aws iam attach-role-policy --role-name "${ROLE_NAME}" --policy-arn ${POLICY_ARN}
4.9.1.1.1. Setting Velero CPU and memory resource allocations

You set the CPU and memory resource allocations for the Velero pod by editing the DataProtectionApplication custom resource (CR) manifest.

Prerequisites

  • You must have the OpenShift API for Data Protection (OADP) Operator installed.

Procedure

  • Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations block of the DataProtectionApplication CR manifest, as in the following example: 

    apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: <dpa_sample>
spec:
# ...
  configuration:
    velero:
      podConfig:
        nodeSelector: <node_selector> 1
        resourceAllocations: 2
          limits:
            cpu: "1"
            memory: 1024Mi
          requests:
            cpu: 200m
            memory: 256Mi
    1
    Specify the node selector to be supplied to Velero podSpec.
    2
    The resourceAllocations listed are for average usage.
Note

Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover.

Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly.

4.9.1.2. Installing the OADP Operator and providing the IAM role

AWS Security Token Service (AWS STS) is a global web service that provides short-term credentials for IAM or federated users. This document describes how to install OpenShift API for Data Protection (OADP) on an AWS STS cluster manually.

Important

Restic and Kopia are not supported in the OADP AWS STS environment. Verify that the Restic and Kopia node agent is disabled. For backing up volumes, OADP on AWS STS supports only native snapshots and Container Storage Interface (CSI) snapshots.

In an AWS cluster that uses STS authentication, restoring backed-up data in a different AWS region is not supported.

The Data Mover feature is not currently supported in AWS STS clusters. You can use native AWS S3 tools for moving data.

Prerequisites

  • An OpenShift Container Platform AWS STS cluster with the required access and tokens. For instructions, see the previous procedure Preparing AWS credentials for OADP. If you plan to use two different clusters for backing up and restoring, you must prepare AWS credentials, including ROLE_ARN, for each cluster.

Procedure

  1. Create an OpenShift Container Platform secret from your AWS token file by entering the following commands:

    1. Create the credentials file: 

      $ cat <<EOF > ${SCRATCH}/credentials
  [default]
  role_arn = ${ROLE_ARN}
  web_identity_token_file = /var/run/secrets/openshift/serviceaccount/token
EOF

    2. Create a namespace for OADP: 

      $ oc create namespace openshift-adp

    3. Create the OpenShift Container Platform secret: 

      $ oc -n openshift-adp create secret generic cloud-credentials \
  --from-file=${SCRATCH}/credentials
      Note

      In OpenShift Container Platform versions 4.14 and later, the OADP Operator supports a new standardized STS workflow through the Operator Lifecycle Manager (OLM) and Cloud Credentials Operator (CCO). In this workflow, you do not need to create the above secret, you only need to supply the role ARN during the installation of OLM-managed operators using the OpenShift Container Platform web console, for more information see Installing from OperatorHub using the web console.

      The preceding secret is created automatically by CCO.

  2. Install the OADP Operator:

    1. In the OpenShift Container Platform web console, browse to Operators → OperatorHub.
    2. Search for the OADP Operator.
    3. In the role_ARN field, paste the role_arn that you created previously and click Install.

  3. Create AWS cloud storage using your AWS credentials by en
