The ON-Bar Tables

ON–Bar uses the following catalog tables in the sysutils database to track backup and restore operations:

• The bar_server table tracks instances of the database server.
• The bar_object table tracks backup objects. A backup object is a backup of a dbspace, blobspace, sbspace, or logical-log file.
• The bar_action table tracks all backup and restore attempts against each backup object, except some log salvage and cold restore events.
• The bar_instance table describes each object that is backed up during a successful backup attempt.

The onsmsync utility uses the following tables to track its operations:

• The bar_ixbar table contains history of all unexpired successful backups in all timelines. It is maintained and used by onsmsync only.
• The bar_syncdeltab table is normally empty except when onsmsync is running. It is maintained and used by onsmsync only.

For a description of the content of these tables, see ON-Bar Catalog Tables.
