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.

Ensure that needed device are available

Verify that storage devices and files are available before you begin a restore. For example, when you drop a dbspace or mirroring for a dbspace after your level-0 backup, you must ensure that the dbspace or mirror chunk device is available to the database server when you begin the restore. If the storage device is not available, the database server cannot write to the chunk and the restore fails.

When you add a chunk after your last backup, you must ensure that the chunk device is available to the database server when it rolls forward the logical logs.
