About Netbackup Catalogs
NetBackup catalogs are the internal databases that contain 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.
Since NetBackup needs the catalog information so that it can restore client backups, configure a catalog backup before using NetBackup for regular client backups. Schedule the catalog backups to occur on a regular basis. Without regular catalog backups, you risk losing regular backups if there is a problem with the disk that contains the catalogs.
Parts of the NetBackup catalog on Windows
The NetBackup catalog resides on the NetBackup master server.
