About Vendor Change Tracking
Several NAS storage array vendors have a difference engine that identifies the list of changed files and directories between two snapshot copies of the same volume. When Vendor Change Tracking (VCT) is enabled for a D-NAS policy, NetBackup does not perform any filesystem tracking for backup of NAS volumes. Instead it relies only on the change-list provided by the difference engine of the storage array to perform backup of files and directories. This optimizes the backup process.
In order to use this feature, you must ensure that the storage that array you are using, provides this capability. D-NAS policy supports VCT enabled backups for Dell EMC PowerScale (Isilon), Nutanix Files, and Qumulo NAS arrays.
VCT is not applicable in the following conditions:
Schedule type is other than INCR and CINR. It's only supported for INCR and CINR.
Base snapshot is not available.
Expired after copy retention options is selected for snapshot in SLP.
