Velero backup fails with FailedValidation error

Description

When attempting to run a scheduled backup in Automation Suite on EKS/AKS, Velero may return the following error:

Phase: FailedValidation
Validation errors: an existing backup storage location was not specified at backup creation time and the server default default does not exist.
Error: BackupStorageLocation.velero.io "default" not found
Phase: FailedValidation
Validation errors: an existing backup storage location was not specified at backup creation time and the server default default does not exist.
Error: BackupStorageLocation.velero.io "default" not found

This occurs due to the default-bs1 BackupStorageLocation not being marked as default in the Velero configuration.

Solution

To address the issue, take the following steps:

  1. Verify the backup storage locations configured for Velero:

    kubectl get backupstoragelocations -n velero
    kubectl get backupstoragelocations -n velero
    

    Confirm whether the DEFAULT column is empty.

  2. Edit the backup storage location to set the default value:

    kubectl edit backupstoragelocation default-bs1 -n velero
    kubectl edit backupstoragelocation default-bs1 -n velero
    
  3. Under the spec section, add the following line:

    default: true
    default: true
    
  4. Save the changes.

  5. Restart the Velero pods to apply the configuration:

    kubectl delete pod -n velero --all
    kubectl delete pod -n velero --all
    

    Alternatively, perform a rolling restart:

    kubectl -n velero rollout restart deploy/velero
    kubectl -n velero rollout restart deploy/velero
    
  6. Verify the fix:

    kubectl get backupstoragelocations -n velero
    kubectl get backupstoragelocations -n velero
    

Confirm that the PHASE is Available and the DEFAULT column shows Yes.
