About NetApp SnapDiff support
NetBackup integrates NetApp SnapDiff technology to enable indexing and backup of NetApp NAS volumes and shares. You can use NetApp SnapDiff v2 or v3 to perform VCT-enabled backups for NetBackup NAS-Data-Protection policy type. To enable NetApp SnapDiff, set the USE_SNAPDIFF_FOR_NETAPP_DNAS_BACKUPS parameter in the bp.conf file to 1, on the NetBackup primary server.
Refer to the NetApp communication CPC-00352 regarding the effect on third-party applications.
Consider the following for SnapDiff-enabled backups of NetApp NAS volumes and shares:
The destination storage that you use for the backup copies must reside on NetApp storage. This condition does not apply to the snapshot or replica copies.
Use only NetApp storage for the NAS share backups, and any other copies that are created using duplication or Auto Image Replication (AIR).
NetBackup supports the following storage units for storing backup, duplicate, and replicate copies:
MSDP storage residing on NetApp
NetApp StorageGRID (LAN)
NetApp StorageGRID (WAN)
