About the NetBackup catalog
A NetBackup catalog is the internal database that contains information about NetBackup backups and configuration. Backup information includes records of the files that have been backed up and the media on which the files are stored. The catalogs also contain information about the media and the storage devices.
Configure a disaster recovery pass phrase and a catalog backup before you run any regular backups. NetBackup needs information from the catalog to determine where the backups of files are located. Without a catalog, NetBackup cannot restore data.

See Configuring catalog backups.
As additional protection for the catalog, consider archiving the catalog.
