Auto Backup Problem

We are using two server-based Databases with multiple uses with different collaboration projects.

However, the Auto backup Settings in the Frist Database Backup seem to work fine (i can see all old files in the Project manager window with all backup editions).
In the other (currently more important) Database i have also activated the backups on one client but resolve does not seem to write them at the desired folder. And on other clients i can activate the auto backup, just to find it deactivated the next time I will open it.

Any Suggestion?

Same issue here. Users check Project Backups and save the prefs. When users return to the prefs, Project Backups is once again unchecked.
