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.

Make sure enough logical-log space exists

When the total available space in the logical log amounts to less than half a single logical-log file, the database server does not create a backup. You must back up the logical-log files and attempt the backup again.

You cannot add mirroring during a backup.

Important: When you use only one available tape device, make sure you back up all your logical-log files before you start your backup to reduce the likelihood of filling the logical log during the backup.
