OADP-1.1 data mover picking the wrong snapshot to restore from.md

When creating backup

• TODO:

When restoring During volumesnapshots.snapshot.storage.k8s.io restoreItemAction when VOLUME_SNAPSHOT_MOVER Env is true We wait for VolumeSnapshot.spec.Source.PersistentVolumeClaimName to be populated

• this is populated by volsync I think. We get VolumeSnapshotRestoreList using restoreName, PVC.Name.
• The list option used to get this list is

    VSRListOptions := client.MatchingLabels(map[string]string{
    		velerov1api.RestoreNameLabel: restoreName,
    		PersistentVolumeClaimLabel:   PVCName,
    	})

• When this list is returned, we assume the first volumeSnapshotRestore in the list is the one meant for this restore.

			if len(vsrList.Items) > 0 {
				snapHandle = vsrList.Items[0].Status.SnapshotHandle
			} else {

• If more than one VSR in the cluster has this label (failed cleanup etc.), we're screwed.

Restore issue workarounds

• Try restore using different name
• Try removing VolumeSnapshotRestore objects in the cluster prior to creating a new restore.
