Backup or restore fails for large sized PVC
For large sized PVC, Backup from Snapshot and Restore from Snapshot/Restore from Backup fails when PVC does not get bound in configured polling timeout. This issue happens because hydration for large volume snapshots takes more time than default 15 minutes timeout.
Backup from Snapshot

Recommended action:
Increase the polling timeout in the backup operator .
