About the Catalog utility

Use the Catalog utility to create and configure catalog backups. Catalog backups are required for NetBackup to protect NetBackup internal databases. The catalogs contain setup information as well as critical information about client backups. The catalog backups are tracked separately from other backups to ensure recovery in case of a server crash.

The Catalog utility is also used to perform the following actions:

Search for backup images to verify the contents of media with what is recorded in the NetBackup catalog.
Duplicate a backup image.
Promote a backup image from a copy to the primary backup copy.
Expire backup images.
Import expired backup images or images from another NetBackup server.
