The catalog backup process
The catalog backup performs the following tasks:
Backs up the catalog while continual client backups are in progress.
Performs a full or an incremental catalog backup.
Runs the scheduled catalog backups.
Copies the databases to the staging directory and then backs up that directory.
Creates the disaster recovery package.
Catalog backups that are made to tape also include the following items:
Spans multiple tapes for a catalog backup.
Allows for a flexible pool of catalog tapes.
Catalog backups to tape use media from the CatalogBackup volume pool only.
Appends to existing data on tape.
When an online catalog backup is run with the multi-steaming setting set to 4, it generates 7 jobs:
1 parent job
1 child job for relational database staging
1 child job for backup of those tables
1 child job for configuration data backup
3 child jobs for NetBackup image database
The child jobs contain the actual backed up data. Consider all child jobs to duplicate, verify, or expire the backup.
