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.
ON-Bar backup and restore system
Overview of the ON-Bar backup and restore systemON-Bar consists of various components and it works with a storage manager to back up and restore data.
ON-Bar componentsON-Bar components include a command-line utility, catalog tables, an activity log, and an emergency boot file. You use ON-Bar with a storage manager and the XBSA shared library for the storage manager.

bar_act.log file: ON-Bar activity log

ON-Bar writes informational, progress, warning, error, and debugging messages to the ON-Bar activity log, bar_act.log.

ON-Bar backup and restore errors do not appear in standard output. If an error occurs when you back up and restore data, check information in the ON-Bar activity log

You can also use the activity log to:

Monitor backup and restore activities such as, which storage spaces and logical logs were backed up or restored, the progress of the operation, and approximately how long it took.
Verify whether a backup or restore succeeded.
Track errors from the ondblog utility.
Track ON-Bar performance statistics

The ON-Bar activity log is in the /tmp directory on UNIX™ and in the %INFORMIXDIR%\etc directory on Windows™. You specify the location of the ON-Bar activity log with the BAR_ACT_LOG configuration parameter.
