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.

The database server can operate online when you back up logical-log files. To back up all full logical-log files, use the -a option of the ontape command.

Figure 1: Request a logical-log backup

The -a option backs up all full logical-log files and prompts you with an option to switch the logical-log files and back up the formerly current log.

When the tape mounted on LTAPEDEV becomes full before the end of the logical-log file, ontape prompts you to mount a new tape.

When you press the Interrupt key while a backup occurs, the database server finishes the backup and then returns control to you. Any other full logical-log files receive a used status.

To back up all full logical-log files, execute the ontape -a command.
