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.

Back up logical-log files

Before you start a warm restore (even when you perform the warm restore as part of a mixed restore), you must back up your logical-log files. See Back up logical-log files with ontape.

After the warm restore, you must roll forward your logical-log files to bring the dbspaces that you are restoring to a state of consistency with the other dbspaces in the system. Failure to roll forward the logical log after restoring a selected dbspace results in the following message from ontape:

Partial system restore is incomplete.
