      • Overview of backup and restoreThese topics provide an overview of backup and restore concepts. They also provide information about planning for backup and restore operations.
      • ON-Bar backup and restore system
        • Overview of the ON-Bar backup and restore systemON-Bar consists of various components and it works with a storage manager to back up and restore data.
        • Configure the storage manager and ON-BarThe topics in this section provide the information that you need to plan and to set up ON-Bar with a storage manager.
        • Back up with ON-BarYou can use the ON-Bar utility to back up and verify storage spaces (dbspaces, blobspaces, and sbspaces) and logical-log files.

        • External backup and restore
          • External backup and restore overviewAn external backup and restore eliminates the downtime of systems because the backup and restore operations are performed external to the HCL® OneDB® system.
            • Block before backing upBefore you begin an external backup, block the database server. Blocking forces a checkpoint, flushes buffers to disk, and blocks user transactions that involve temporary tables.
            • Rules for an external backup
            • Prepare for an external backup
              • Block and unblock database server
