[PROBLEM] Update questions and XBIAN config problems

[IngoVals]

So I haven't updated in a long time. I currently have Alpha 5 build.

So I was thinking if I could update easily from that to newest stable, RC2 or something. Is this possible?

I looked at the wiki and it talks about using xbian-config. In settings under Xbian there is a update interface that just says "up to date". But I found Xbian-config under programs but I cant select it, the program just doesnt seem to respond or take to much time starting up. If I try entering xbian settings after I try to start up xbian-config I get a popup saying "config still running" or something like that.

Last thing, should I backup before updating? I see the wiki mention that there are snapshots taken before updates (at least apt update) but not sure if that is a relialbe feature that was present in Alpha 5.
