Backup not running during clone - Networker v18

Hi.

I'm quite new to Networker - and we have now a clone job running on one policy group. (to tape)

This startet yesterday - and there has been running no backups in this group last night - except for Distaster recovery:\ and Windows Roles and Features:\

Is this by design - that backup will not run while there is a cloning job running for backup in a group? Or is there something I can do - to make sure that backup will run  tonight?

Regards
