Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar utility to back up and restore database server data. This will enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.
ON-Bar backup and restore system
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.
onbar -b syntax: Backing upUse the onbar -b command to back up storage spaces and logical logs.
Use ISM during a backupUse the ism_watch command to monitor backups and restores sent to the HCL® OneDB® Storage Manager server. During a backup, the ISM server automatically routes storage-space data to volumes in the ISMData volume pool and logical-log files to volumes in the ISMLogs volume pool.

Use ISM during a backup

Use the ism_watch command to monitor backups and restores sent to the HCL® OneDB® Storage Manager server. During a backup, the ISM server automatically routes storage-space data to volumes in the ISMData volume pool and logical-log files to volumes in the ISMLogs volume pool.

Always keep the volumes from the ISMLogs pool mounted to ensure that a storage device is always available to accept logical-log data. If the volume is not mounted, the backup pauses. For more information about using devices and ISM commands, see the .

During the backup operation, ISM creates save sets of the backed up data and enters information about the backed up data in the ISM catalog. You can also use the ism_catalog -create_bootstrap command to back up the ISM catalog:

If you use the onbar script to back up storage spaces and logical logs, it backs up the ISM catalog automatically. If you call onbar_d directly, you must use the ism_catalog -create_bootstrap command.
