Oops… I think I found a bug / have a feature request.
One of my windows users was able to right-click on the UrBackup client (version 2.0.20) in the system tray and selected “Accss/restore backups”. The user who was unfamiliar with the way UrBackup works, simply hit the restore button on the first page shown (basically restoring his entire C:\ drive from an earlier backup); thus erasing his current work for the last few hours 
I also noticed that if a windows user reboots and then right-clicks on the client icon in the system tray before the client connects to the server, the options are not restricted to what I set on the server. The options are the default (allow most). I’m not sure if they will be allowed to change settings, but they can see the options until the client connects to the server.
I would like to see an option in the server settings (permissions tab) that can block the users from restoring files. (to avoid the accidental overwriting of files). Please remember that some users are barely able to turn a computer on; they certainly are not expert in matters of file systems and consequences of overwriting files. If possible, it might also be more consistent for the client to store the last server permission restrictions so the client can only see the permitted options on the next reboot.
In case you don’t hear it enough: Excellent software, Thank you!
