Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

Restore save sets with ISM

Restore save sets with ISM

If you are using HCL® OneDB® Storage Manager , you can restore data from save sets on the storage volume. When the ISM server receives a restore request, the ism_watch command prompts you to mount the required storage volume on the storage device. When you mount the volume, the restore resumes.

You can set the retention period for either a save set or volume. Unless all the save sets on the volume are expired, you can use ON-Bar to restore it.

After the retention period for a save set expires, ON-Bar can no longer restore it. To recreate an expired save set, use the ism_catalog -recreate from command.

If you set the retention period for a volume, ISM retains the save sets until all the save sets on that volume are expired. To recover an expired volume, use the ism_catalog -recover from command.
