-q|-query 

Input syntax: -q [check]

Default value: The backup is started.

When you select the -q option, you find out which volumes (e.g. tapes) must be mounted for the backup process. In this case, backup is not started. Before you start a backup request with CRON, you should use this option to find out which volumes are required.

The preparation for an unattended backup to tapes could be performed as follows:

Once you have made these preparations, you can start an unattended backup on the same day, since you have already checked the validity of the tapes.
