About recovering the NetBackup catalog
Before you recover the NetBackup catalog, you must do the following:
Ensure that NetBackup is running in the recovery environment.
Configure the recovery devices NetBackup.
Ensure that the media on which the catalog backups exist are available to NetBackup.
If the NetBackup master server is part of a cluster, ensure that the cluster is functional.
Restore the NetBackup host identity by restoring the disaster recovery package.
After successful catalog recovery, you must set the disaster recovery package passphrase, because the passphrase is not recovered during the catalog recovery.
The NetBackup catalog consists of several parts. How you recover the catalog depends on which part or parts of the catalog you want to recover, as follows:

Recover the entire catalog
Veritas recommends that you recover the entire catalog. Doing so helps ensure consistency among the various parts of the catalog. This method is most useful for recovering a catalog to the same environment from which it was backed up.
Recover the catalog image files and configuration files
The image database contains information about the data that has been backed up. The configuration files (
This type of recovery also restores the NetBackup relational database (NBDB) to the staging directory so that it is available for further processing if required.
Recover the relational database files
The NetBackup database (NBDB) is also known as the Enterprise Media Manager (EMM) database. It contains information about volumes and the robots and drives that are in NetBackup storage units. The NetBackup relational database also contains the NetBackup catalog images files. The images files contain the metadata that describes the backups.
Recover the relational database if it is corrupt or lost but the catalog image files exist and are valid.
Recovery of the entire catalog or the catalog image files relies on the disaster recovery information. That information is saved in a file during the catalog backup. The location of the disaster recovery file is configured in the catalog backup policy.
If you do not have the disaster recovery file, you still can recover the catalog. However, the process is much more difficult and time-consuming.
After a catalog recovery, NetBackup freezes the removeable media that contains the catalog backup. This operation prevents a subsequent accidental overwrite action on the final catalog backup image on the media. This final image pertains to the actual catalog backup itself, and its recovery is not part of the catalog recovery. You can unfreeze the media.
Other procedures exist for special use cases.
