Solution Verified - Updated -

Environment

  • Red Hat OpenShift Container Platform (RHOCP)
    • 4.12
  • OpenShift API for Data Protection

Issue

  • Backup is created but does not sync with the Attempting to sync backup into cluster message in the Velero logs.

Resolution

  • UseOwnerReferencesBackup specifies whether to use OwnerReferences on backups created by this schedule.

  • Add useOwnerReferencesInBackup: true in the back-up CRD YAML as shown below.

    $ oc edit backup <backup-name> -n openshift-adp 

    storageLocation: velero-1
    ttl: 336h0m0s
  useOwnerReferencesInBackup: true   <-------------

Root Cause

The application changes to OutOfSync if the backup is linked to the schedule, the situation remains Synced.

Diagnostic Steps

  • Check for the Attempting to sync backup into cluster and Found 3 backups in the backup location that do not exist in the cluster and need to be synced messages in the Velero logs:

    $ oc logs <velero-pod-name> -n openshift-adp
time="20XX-XX-XXT19:22:ZZZ" level=info msg="Attempting to sync backup into cluster" backup=backup-secrets-14- 
202020202021 backupLocation=openshift-adp/velero-1 controller=backup-sync logSource="/remote- 
source/velero/app/pkg/controller/backup_sync_controller.go:143"

  • The backups are not shown:

    $ oc get backups -n openshift-adp
No resources found in openshift-adp namespace.
