Interpreting Verification Messages

When you verify a backup, ON–Bar writes summary messages to the bar_act.log that report which storage spaces were verified and whether the verification succeeded or failed. The archecker utility writes detailed messages to the ac_msg.log. Technical Support uses the ac_msg.log to diagnose problems with backups and restores.

Sample Verification Message in the ON-Bar Activity Log

The level-0 backup of dbspace dbs2.2 passed verification, as follows:

Completed level-0 backup verification successfully.

The level-0 backup of rootdbs failed verification, as follows:

ERROR: Unable to close the physical check: error_message.
