Chapter 14. Backup and restore

Procedure

1. Display the output from the snapshot indications by performing one of the following actions:

   • Use the command line to view indicator output in the status stanza of the VirtualMachineSnapshot object YAML.
   • In the web console, click VirtualMachineSnapshot Status in the Snapshot details screen.

2. Verify the status of your online VM snapshot by viewing the values of the status.indications parameter:

   • Online indicates that the VM was running during online snapshot creation.
   • GuestAgent indicates that the QEMU guest agent was running during online snapshot creation.
   • NoGuestAgent indicates that the QEMU guest agent was not running during online snapshot creation. The QEMU guest agent could not be used to freeze and thaw the file system, either because the QEMU guest agent was not installed or running or due to another error.

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.

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:
           - kubevirt 2
           - gcp 3
           - csi 4
           - openshift 5
         resourceTimeout: 10m 6
       nodeAgent: 7
         enable: true 8
         uploaderType: kopia 9
         podConfig:
           nodeSelector: <node_selector> 10
     backupLocations:
       - velero:
           provider: gcp 11
           default: true
           credential:
             key: cloud
             name: <default_secret> 12
           objectStorage:
             bucket: <bucket_name> 13
             prefix: <prefix> 14

   1

   The default namespace for OADP is openshift-adp. The namespace is a variable and is configurable.

   2

   The kubevirt plugin is mandatory for OpenShift Virtualization.

   3

   Specify the plugin for the backup provider, for example, gcp, if it exists.

   4

   The csi plugin is mandatory for backing up PVs with CSI snapshots. The csi plugin uses the Velero CSI beta snapshot APIs. You do not need to configure a snapshot location.

   5

   The openshift plugin is mandatory.

   6

   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.

   7

   The administrative agent that routes the administrative requests to servers.

   8

   Set this value to true if you want to enable nodeAgent and perform File System Backup.

   9

   Enter kopia as your uploader to use the Built-in DataMover. 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.

   10

   Specify the nodes on which Kopia are available. By default, Kopia runs on all nodes.

   11

   Specify the backup provider.

   12

   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.

   13

   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.

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

   $ 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
