A representation of the results of performing a backup of servers on a network. Backup software such as the Microsoft Windows NT administrative tool Windows NT Backup and Backup in Windows 2000 create catalogs so that backed up files are documented and can be found when performing a restore. Windows NT Backup stores its catalogs on the backup storage media themselves. These catalogs are then loaded into memory when the program is run. Catalogs can also be saved to disk and can be printed for documentation purposes.
On the Windows NT platform, the administrative tool Windows NT Backup creates two different types of backup catalogs:
If a backup operation spans several tapes and the last tape is missing or damaged, the tape catalog will not be available. However, you can still obtain a complete list of the various backup sets on the tapes by running Windows NT Backup from the command line using the ntbackup command with the /missingtape switch.
