Using VCT along with accelerator for D-NAS
With NetBackup 10.2 onwards the NetBackup you can enable accelerator along with VCT in the NAS-Data-Protection policies for the NAS backups. VCT with accelerator technology are supported with Nutanix, Qumulo, and Isilon storage arrays.
During incremental backups, NetBackup can leverage the storage array vendor's technology to get the list of the added, modified, and deleted files between the two point-in-time snapshots. During incremental backups NetBackup need not do a complete evaluation of the NAS volumes to determine the modified files.
A policy enables accelerator, just after the initial full backup. For the subsequent full backups the NetBackup client (backup host) sends only the changed data to the media server.
Combining both these functionalities in a single backup policy, the backup window is greatly reduced for the full and incremental backups.
