Values:
VOLUME_DATA_RESTORE_POLICY_UNSPECIFIED (0):
Unspecified (illegal).
RESTORE_VOLUME_DATA_FROM_BACKUP (1):
For each PVC to be restored, create a new
underlying volume and PV from the corresponding
VolumeBackup contained within the Backup.
REUSE_VOLUME_HANDLE_FROM_BACKUP (2):
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.
NO_VOLUME_DATA_RESTORATION (3):
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.
