Cannot backup my freepbx

Backups should not be this hard!!

Any idea how to get the backup module working?

If I create a backup and schedule it for ‘Now’ the system sends me an empty tar.gz file in an email.

If I schedule a monthly backup, I get an email with this message even though I have never set these permissions on my own:
