About recovering the NetBackup catalog image files

The catalog image files contain information about all the data that has been backed up. This information constitutes the largest part of the NetBackup catalog. This type of catalog recovery does the following:

Recovers the image .f files.
Recovers the configuration files (databases.conf and server.conf).
Restores the NetBackup relational database (NBDB) to the staging directory so that it is available for further processing if required.
See About processing the relational database in staging.
Optionally, recovers the policy and the licensing data.

Note:

The image files are stored in the NetBackup relational database. The images files contain the metadata that describes the backups.

NetBackup supports recovery of the catalog image files and configuration files from a clustered environment to a non-clustered master server at a disaster recovery.

Recovery recommendations

See About NetBackup catalog recovery and symbolic links.

Veritas recommends that you recover the catalog images files in the following scenarios:

The NetBackup relational database is valid, but NetBackup policy, backup image, or configuration files are lost or corrupt.
You want to restore part of the NetBackup catalog before you restore the entire catalog. This procedure recovers only the catalog images and configuration files.
After you recover the image files, you can recover the relational database.
You recover the catalog using different storage devices. It may be to the same environment after storage hardware failure or replacement. It may be another site to which you replicate the catalog backups and the client backups. Regardless, the catalog backups and the client backups reside on different hardware.
This recovery does not overwrite the new storage device configuration with the old, no longer valid storage device information from the catalog backup.

Catalog recovery and backup types

Recovery includes the catalog image files and configuration files that are in the catalog backups listed in the disaster recovery file, as follows:

Full backup

The image files and configuration files that are listed in the disaster recovery file are recovered.

Incremental backup

Two recover scenarios exist, as follows:

The catalog contains no information about the corresponding full backup and other incremental backups.
NetBackup restores only the backup image .f files, configuration files, and NetBackup policy files that are backed up in that incremental backup.
However, all of the catalog backup image .f files up to the last full catalog backup are restored. Therefore, you can restore the rest of the policy, image .f files, and configuration files by using the Backup, Archive and Restore interface.
The catalog contains information about the corresponding full backup and other incremental backups.
NetBackup restores all of the backup image .f files and the configuration files that were included in the related set of catalog backups.

Recovery methods

You can use either of the following methods to recover the catalog image files:

The Catalog Recovery Wizard in the NetBackup Administration Console.
See Recovering the entire NetBackup catalog using the Catalog Recovery Wizard.
The text-based recovery wizard. The bprecover -wizard command and option start the text-based recovery wizard.
See Recovering the entire NetBackup catalog using bprecover -wizard.
