Backup and restore

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
   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "ec2:DescribeVolumes",
                   "ec2:DescribeSnapshots",
                   "ec2:CreateTags",
                   "ec2:CreateVolume",
                   "ec2:CreateSnapshot",
                   "ec2:DeleteSnapshot"
               ],
               "Resource": "*"
           },
           {
               "Effect": "Allow",
               "Action": [
                   "s3:GetObject",
                   "s3:DeleteObject",
                   "s3:PutObject",
                   "s3:AbortMultipartUpload",
                   "s3:ListMultipartUploadParts"
               ],
               "Resource": [
                   "arn:aws:s3:::${BUCKET}/*"
               ]
           },
           {
               "Effect": "Allow",
               "Action": [
                   "s3:ListBucket",
                   "s3:GetBucketLocation",
                   "s3:ListBucketMultipartUploads"
               ],
               "Resource": [
                   "arn:aws:s3:::${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.

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"
           credential:
             key: cloud
             name: cloud-credentials 7
     snapshotLocations: 8
       - name: default
         velero:
           provider: aws
           config:
             region: <region> 9
             profile: "default"

   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 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.

   8

   Specify a snapshot location, unless you use CSI snapshots or Restic to back up PVs.

   9

   The snapshot location must be in the same region as the PVs.

4. Click Create.

5. Verify the installation by viewing the OADP resources:

   $ oc get all -n openshift-adp

   Example output

8. Obtain the storage account access key:

   $ AZURE_STORAGE_ACCOUNT_ACCESS_KEY=`az storage account keys list \
     --account-name $AZURE_STORAGE_ACCOUNT_ID \
     --query "[?keyName == 'key1'].value" -o tsv`

9. Create a custom role that has the minimum required permissions:

   AZURE_ROLE=Velero
   az role definition create --role-definition '{
      "Name": "'$AZURE_ROLE'",
      "Description": "Velero related permissions to perform backups, restores and deletions",

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.disks.get
       compute.disks.create
       compute.disks.createSnapshot
       compute.snapshots.get
       compute.snapshots.create
       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.

             snapshotLocation: us-west1 9

   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

   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.

   6

   Specify a bucket as the backup storage location. If the bucket is not a dedicated bucket for Velero backups, you must specify a prefix.

   7

   Specify a prefix for Velero backups, for example, velero, if the bucket is used for multiple purposes.

   8

   Specify a snapshot location, unless you use CSI snapshots or Restic to back up PVs.

   9

   The snapshot location must be in the same region as the PVs.

4. Click Create.

5. Verify the installation by viewing the OADP resources:

   $ oc get all -n openshift-adp

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.

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:

             prefix: <prefix> 8

   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 URL of the S3 endpoint.

   6

   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.

   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.

4. Click Create.

5. Verify the installation by viewing the OADP resources:

   $ oc get all -n openshift-adp

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 in order 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 use Restic to restore DeploymentConfig objects or if you use post-restore hooks, run the dc-restic-post-restore.sh cleanup script by entering the following command:

   $ bash dc-restic-post-restore.sh <restore-name>

   Note

   In the course of the restore process, the OADP Velero plug-ins scale down the DeploymentConfig objects and restore the pods as standalone pods to prevent the cluster from deleting the restored DeploymentConfig pods immediately on restore and to allow Restic and post-restore hooks to complete their actions on the restored pods. The cleanup script removes these disconnected pods and scale any DeploymentConfig objects back up to the appropriate number of replicas.

   Example 4.1. dc-restic-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}"
   }
   
   OADP_NAMESPACE=${OADP_NAMESPACE:=openshift-adp}
   
   if [[ $# -ne 1 ]]; then
       echo "usage: ${BASH_SOURCE} restore-name"
       exit 1
   fi
   
   echo using OADP Namespace $OADP_NAMESPACE
   echo restore: $1
   
   label=$(label_name $1)
   echo label: $label
   
   echo Deleting disconnected restore pods
   oc delete pods -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

Procedure

1. Create a YAML file for the Backup object, as in the following example:

   Example Backup CR

   kind: Backup
   apiVersion: velero.io/v1
   metadata:
     name: backup
     namespace: openshift-adp
   spec:
     csiSnapshotTimeout: 10m0s
     defaultVolumesToFsBackup: false
     includedNamespaces:
     - mysql-persistent
     itemOperationTimeout: 4h0m0s
     snapshotMoveData: true 1
     storageLocation: default
     ttl: 720h0m0s
     volumeSnapshotLocations:
     - dpa-sample-1
   # ...

   1

   Set to true to enable movement of CSI snapshots to remote object storage.

2. Apply the manifest:

   $ oc create -f backup.yaml

   A DataUpload CR is created after the snapshot creation is complete.

Procedure

1. Create a YAML file for the Restore CR, as in the following example:

   Example Restore CR

   apiVersion: velero.io/v1
   kind: Restore
   metadata:
     name: restore
     namespace: openshift-adp
   spec:
     backupName: <backup>
   # ...

2. Apply the manifest:

   $ oc create -f restore.yaml

   A DataDownload CR is created when the restore starts.

Procedure

1. Run one of the following commands to retrieve a list of BSLs:

   1. Using the OpenShift CLI:

      $ oc get backupstoragelocation -A

   2. Using the Velero CLI:

      $ velero backup-location get -n <OADP_Operator_namespace>

2. Using the list of BSLs, run the following command to display the manifest of each BSL, and examine each manifest for an error.

   $ oc get backupstoragelocation -n <namespace> -o yaml

Solution

1. Edit the value of the spec.snapshotLocations.velero.config.region key in the DataProtectionApplication manifest so that the snapshot location is in the same region as the PV.
2. Create a new Backup CR.

Solution

1. Retrieve the details of the Backup CR:

   $ oc -n {namespace} exec deployment/velero -c velero -- ./velero \
     backup describe <backup>

2. Delete the Backup CR:

   $ oc delete backup <backup> -n openshift-adp

   You do not need to clean up the backup location because a Backup CR in progress has not uploaded files to object storage.

3. Create a new Backup CR.

Solution

1. Delete the Backup CR:

   $ oc delete backup <backup> -n openshift-adp

2. If required, clean up the stored data on the BackupStorageLocation to free up space.

3. Apply label velero.io/csi-volumesnapshot-class=true to the VolumeSnapshotClass object:

   $ oc label volumesnapshotclass/<snapclass_name> velero.io/csi-volumesnapshot-class=true

4. Create a new Backup CR.

1. Create a supplemental group for Restic on the NFS data volume.
2. Set the setgid bit on the NFS directories so that group ownership is inherited.

3. Add the spec.configuration.restic.supplementalGroups parameter and the group ID to the DataProtectionApplication manifest, as in the following example:

   spec:
     configuration:
       restic:
         enable: true
         supplementalGroups:
         - <group_id> 1

   1

   Specify the supplemental group ID.

4. Wait for the Restic pods to restart so that the changes are applied.

Procedure

1. Edit the cluster-monitoring-config ConfigMap object in the openshift-monitoring namespace:

   $ oc edit configmap cluster-monitoring-config -n openshift-monitoring

2. Add or enable the enableUserWorkload option in the data section’s config.yaml field:

   apiVersion: v1
   data:
     config.yaml: |
       enableUserWorkload: true 1
   kind: ConfigMap
   metadata:
   # ...

   1

   Add this option or set to true

3. Wait a short period of time to verify the User Workload Monitoring Setup by checking if the following components are up and running in the openshift-user-workload-monitoring namespace:

   $ oc get pods -n openshift-user-workload-monitoring

   Example output

   NAME                                   READY   STATUS    RESTARTS   AGE
   prometheus-operator-6844b4b99c-b57j9   2/2     Running   0          43s
   prometheus-user-workload-0             5/5     Running   0          32s
   prometheus-user-workload-1             5/5     Running   0          32s
   thanos-ruler-user-workload-0           3/3     Running   0          32s
   thanos-ruler-user-workload-1           3/3     Running   0          32s

4. Verify the existence of the user-workload-monitoring-config ConfigMap in the openshift-user-workload-monitoring. If it exists, skip the remaining steps in this procedure.

   $ oc get configmap user-workload-monitoring-config -n openshift-user-workload-monitoring

   Example output

   Error from server (NotFound): configmaps "user-workload-monitoring-config" not found

5. Create a user-workload-monitoring-config ConfigMap object for the User Workload Monitoring, and save it under the 2_configure_user_workload_monitoring.yaml file name:

   Example output

   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: user-workload-monitoring-config
     namespace: openshift-user-workload-monitoring
   data:
     config.yaml: |

6. Apply the 2_configure_user_workload_monitoring.yaml file:

   $ oc apply -f 2_configure_user_workload_monitoring.yaml
   configmap/user-workload-monitoring-config created

Procedure

1. Ensure the openshift-adp-velero-metrics-svc service exists. It should contain app.kubernetes.io/name=velero label, which will be used as selector for the ServiceMonitor object.

   $ oc get svc -n openshift-adp -l app.kubernetes.io/name=velero

   Example output

   NAME                               TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
   openshift-adp-velero-metrics-svc   ClusterIP   172.30.38.244   <none>        8085/TCP   1h

2. Create a ServiceMonitor YAML file that matches the existing service label, and save the file as 3_create_oadp_service_monitor.yaml. The service monitor is created in the openshift-adp namespace where the openshift-adp-velero-metrics-svc service resides.

   Example ServiceMonitor object

   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
     labels:
       app: oadp-service-monitor
     name: oadp-service-monitor
     namespace: openshift-adp
   spec:
     endpoints:
     - interval: 30s
       path: /metrics
       targetPort: 8085
       scheme: http
     selector:
       matchLabels:
         app.kubernetes.io/name: "velero"

3. Apply the 3_create_oadp_service_monitor.yaml file:

   $ oc apply -f 3_create_oadp_service_monitor.yaml

   Example output

   servicemonitor.monitoring.coreos.com/oadp-service-monitor created

Procedure

1. Create a PrometheusRule YAML file with the sample OADPBackupFailing alert and save it as 4_create_oadp_alert_rule.yaml.

   Sample OADPBackupFailing alert

   apiVersion: monitoring.coreos.com/v1
   kind: PrometheusRule
   metadata:
     name: sample-oadp-alert
     namespace: openshift-adp
   spec:
     groups:
     - name: sample-oadp-backup-alert
       rules:
       - alert: OADPBackupFailing
         annotations:
           description: 'OADP had {{$value | humanize}} backup failures over the last 2 hours.'
           summary: OADP has issues creating backups
         expr: |
           increase(velero_backup_failure_total{job="openshift-adp-velero-metrics-svc"}[2h]) > 0
         for: 5m
         labels:
           severity: warning

   In this sample, the Alert displays under the following conditions:

   • There is an increase of new failing backups during the 2 last hours that is greater than 0 and the state persists for at least 5 minutes.
   • If the time of the first increase is less than 5 minutes, the Alert will be in a Pending state, after which it will turn into a Firing state.

2. Apply the 4_create_oadp_alert_rule.yaml file, which creates the PrometheusRule object in the openshift-adp namespace:

   $ oc apply -f 4_create_oadp_alert_rule.yaml

   Example output

   prometheusrule.monitoring.coreos.com/sample-oadp-alert created
