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.

Full-system restore

When your database server goes offline because of a disk failure or corrupted data, it means that a critical dbspace was damaged. The following list shows critical dbspaces:

The root dbspace
The dbspace that contains the physical log
A dbspace that contains logical-log files

When you need to restore any critical dbspace, you must perform a full system restore to restore all the data that your database server manages. You must start a full-system restore with a cold restore. See Cold, warm, or mixed restores.
