https://redhat-internal.slack.com/archives/C0282HW2YHZ/p1761769756893319?thread_ts=1761729892.038489&cid=C0282HW2YHZ

When using a specific backup name (not "latest"), the credentials restore only creates the -active restore and skips the regular credentials restore.

Expected Behavior:

When restoring managed clusters with credentials, you should restore both regular and activation time credentials ( activation time credentials have the cluster.open-cluster-management.io/backup label set to cluster-activation and they should be restored only when the managed clusters are restored; both regular and activation credentials are backed up under the same backup, credentials backup )

So when restoring managed clusters , all credentials should be restored 

Actual Behavior:

Only the activation credentials are restored , under a restore file with this name :

Active credentials restore: restore-acm-creds-20251029181055-acm-credentials-schedule-20251029181055-active. If you open up this velero resource you can see that it has a label selector which restores only cluster-activation resources

To reproduce, run a restore operation and use the backup name instead of the latest backup. For example use 
apiVersion: cluster.open-cluster-management.io/v1beta1
kind: Restore
metadata:
name: restore-acm-creds-20251029181055
namespace: open-cluster-management-backup
spec:
cleanupBeforeRestore: CleanupRestored
veleroManagedClustersBackupName: acm-managed-clusters-schedule-20251029181055
veleroCredentialsBackupName: acm-credentials-schedule-20251029181055
veleroResourcesBackupName: acm-resources-schedule-20251029181055
 
The restore status shows the credentials backup was not restored

  phase: Finished

  veleroCredentialsRestoreName: restore-acm-creds-20251029181055-acm-credentials-schedule-20251029181055-active<< HERE I should get both -active and regular backup

  veleroGenericResourcesRestoreName: restore-acm-creds-20251029181055-acm-resources-generic-schedule-20251029181055

  veleroManagedClustersRestoreName: restore-acm-creds-20251029181055-acm-managed-clusters-schedule-20251029181055

  veleroResourcesRestoreName: restore-acm-creds-20251029181055-acm-resources-schedule-20251029181055

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:

1. Restore with the attached sample
2. You should see a velero restore for the acm-credentials-schedule-20251029181055, restoring all credentials. 

Actual results: 

1. You get only a velero for acm-credentials-schedule-20251029181055-active. If you open up this velero resource you can see that it has a label selector which restores only cluster-activation resources

Expected results:

1. You should see a velero restore for the acm-credentials-schedule-20251029181055, restoring all credentials. The restore velero resource should have no labelSelector

Additional info: 

I tested with ACM 2.15 but this is an issue with older releases as well
