Dynamic data streaming for D-NAS Policy
Dynamic NAS (D-NAS): By means of Snapshot management server and the storage array plug-ins, NetBackup can make snapshots of NAS volumes and shares. 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 of 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 for a single vendor and 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 data lifecycle.
