   $ aws iam put-user-policy \
     --user-name velero \
     --policy-name velero-s3 \
     --policy-document file://velero-s3-policy.json

7. Create an access key for velero:

   $ aws iam create-access-key --user-name velero
   {
     "AccessKey": {
           "UserName": "velero",
           "Status": "Active",
           "CreateDate": "2017-07-31T22:24:41.576Z",

Procedure

1. Retrieve the backupStorageLocations CRs:

   $ oc get backupStorageLocations

   Example output

   NAME              PHASE       LAST VALIDATED   AGE   DEFAULT
   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
     storageLocation: <velero-sample-1> 2
     ttl: 720h0m0s

   1

   Specify an array of namespaces to back up.

   2

   Specify the name of the backupStorageLocations CR.

3. Verify that the status of the Backup CR is Completed:

   $ oc get backup -n openshift-adp <backup> -o jsonpath='{.status.phase}'

Procedure

1. Retrieve the backupStorageLocations CRs:

   $ oc get backupStorageLocations

   Example output

   NAME              PHASE       LAST VALIDATED   AGE   DEFAULT
   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
       defaultVolumesToRestic: 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.

   2

   Array of namespaces to back up.

   3

   Name of the backupStorageLocations CR.

   4

   Optional: Add the defaultVolumesToRestic: true key-value pair if you are backing up volumes with Restic.

3. 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}'

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
     excludedResources:
     - nodes
     - events
     - events.events.k8s.io
     - backups.velero.io
     - restores.velero.io
     - resticrepositories.velero.io
     restorePVs: true

   1

   Name of the Backup CR.

2. Verify that the status of the Restore CR is Completed:

   $ oc get restore -n openshift-adp <restore> -o jsonpath='{.status.phase}'

3. Verify that the backup resources have been restored:

   $ oc get all -n <namespace> 1

   1

   Namespace that you backed up.

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.

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.

Solution

1. Create a Restore CR that excludes the ReplicationController, DeploymentConfig, and TemplateInstances resources:

   $ velero restore create --from-backup=<backup> -n openshift-adp \ 1
     --include-namespaces <namespace> \ 2
     --exclude-resources replicationcontroller,deploymentconfig,templateinstances.template.openshift.io \
     --restore-volumes=true

   1

   Specify the name of the Backup CR.

   2
