About NAS backups

NetBackup Snapshot Manager and NDMP V4 snapshot extension can make snapshots of client data on a NAS host. A NAS snapshot is a point-in-time disk image. You can retain the Snapshots on the disk for any duration. Using the Instant Recovery feature in NetBackup, you can efficiently restore the data from the disk. In NetBackup, you can use snapshot-based data protection to protect your NAS data, using two policies: NAS-Data-Protection and NDMP.
