For each PVC to be restored, create PVC without any particular
action to restore data. In this case, the normal Kubernetes provisioning
logic would kick in, and this would likely result in either dynamically
provisioning blank PVs or binding to statically provisioned PVs.
RestoreVolumeDataFromBackup
For each PVC to be restored, create a new underlying volume and PV
from the corresponding VolumeBackup contained within the Backup.
ReuseVolumeHandleFromBackup
For each PVC to be restored, attempt to reuse the original PV contained
in the Backup (with its original underlying volume). This option
is likely only usable when restoring a workload to its original cluster.
