Ensure You Have a Catalog Backup Report

The Catalog backup report is essential. It enables you to quickly locate your latest Catalog backup.

When you browse data for restore, the management console displays backup information obtained from the Catalog. When you select data to restore, DPX uses the Catalog to identify the precise location of the backed up data. In the case of automated tape libraries, that information is sent to the media changer controller to pick the correct tape for restore.

But what if the Catalog itself is lost? You need the location of the Catalog backup to restore the Catalog quickly. Particularly, you need the information that precisely identifies the location of the Catalog backup:

  • VOLSER of the tape containing the Catalog backup

  • Partition the Catalog was backed up to on the tape

The Catalog contains this information, but the Catalog is lost.

Fortunately, the information you need is contained in the backup report generated when you perform a backup. Thus, it is critical that you keep the Catalog backup report easily available for use during a disaster recovery.

The easiest way to ensure you have a copy of the Catalog backup report is to have it emailed automatically when the Catalog backup completes.

Note. When you define a Catalog backup, ensure you select the option to email the backup report to a user or group accessible even when the master server is down. It is advisable to send a copy offsite.
