@ Apmuthu : I would love to see a Restore option in the GUI, too! And I'm sure there are more people out there, right?
@ Dietmar : I am just an end-user, not a developer. I noticed there is a page in the Wiki on how to restore a backup but it requires you to SSH to the server. I don't even have an SSH program. My point is: for us end-users a Restore is important, too. When a VM or a node goes down, it usually goes down after office hours or on a Sunday and I can't reach my server admin. I could probably restore it myself if there were a Restore functionality in the GUI. But when I have to SSH, it's out of my league. Regarding the user-management there are always people who won't need that. Personally I just manage my own servers.
