Ensure that you have installed the NetBackup Snapshot Manager component. For more details, see the Veritas NetBackup Snapshot Manager Install and Upgrade Guide.

Prepare the plug-in that you want to use for the NetBackup D-NAS configuration. For more details, refer to the NetBackup™ Snapshot Manager for Data Center Administrator's Guide.

Identify the backup host that you want to use for the configuration.

If the NAS data protection policy uses a TAPE storage unit in SLP for protecting NAS volumes, then the number of tape drives must be greater than or equal to the maximum number of streams per volume, otherwise, backups fail. The other parameters of TAPE, like Media multiplexing and maximum concurrent write drives, do not have any effect on NetBackup D-NAS backups.

For SMB backups using the NAS-Data-Protection policy the primary, media and backup host version should be 9.1 onwards.
