To backup the NBU Catalog, you need to create a new policy and select Catalog_Backup as the type.
Add schedule(s) that will run every day and be sure that the location for the DR-file is on a separate filesystem from the NBU catalogs - preferably a mapped network drive and that email notification is configured to send DR-file and recovery steps as soon as the backup completes.
For detailed instructions, see chapter 22 of NetBackup Administrator's Guide, Volume I :
