Backup Module Cron Exception

Hello
I set up backup in FreePBX Distro (latest) which seems to work. But now I receive the following exceptions when the backup is called by Cron. The backup files itself are created and uploaded to my backup storage (NAS). Any idea who to fix this or get at least more information?

Nobody any idea or the same problem? Do I need to provide something else?

Hi!

Try updating and if it doesn’t work open a ticket at http://issues.freepbx.org.

Good luck and have a nice day!
