Dynamic data streaming for D-NAS Policy

NetBackup can make snapshots of NAS volumes and shares using the Snapshot management server and the storage array plug-ins. The snapshots are accessed on backup hosts and read by dynamic streams to create point-in-time backup copies.

You can perform a snapshot-enabled, off-host backup of NAS volumes, where a volume is backed up using dynamic backup streams.

Each NAS volume or share is read over NFS or SMB, and backed up using a configured number of backup streams. Files from these NAS volumes or shares are optimally distributed in real-time across streams to realize the full potential of backup streams. You cannot mix NAS volumes or shares of different storage array vendors in a single policy. In other words, using a single policy, you can only protect assets of a single vendor, on a single NAS protocol.

Dynamic streaming is built on the NetBackup client framework and uses NAS-Data-Protection policy type for snapshot and backup orchestration of NAS data. This policy supports SLP only for the data lifecycle.
