When to Back Up the Catalog
The frequency of catalog backups is configurable. Choose one of the following options:
After each session of scheduled, user, or manual backups
Consider this option if you are sending your catalog backups to a robot or tape stacker, a second standalone tape drive, or to disk.
After each session of scheduled backups
- Consider this option if you are sending your catalog backups to a robot or tape stacker, a second standalone tape drive, or to disk, or
- if you will be running only one backup session per day or night
Only when manually initiated
Consider this option if you will be running multiple backup sessions in a single day or night. Be certain to perform a manual catalog backup once a day or after a series of backups.
 Caution
It is imperative that you back up your catalogs often. If the catalog backup files are lost, you lose information about backups and configuration changes that were made between the time of the last catalog backup and the time that the disk crash occurred.
