Is there a wiki on backup settings?

[burgertime]

I'm trying to learn all about the xbian backup settings. Auto snapshot vs image, etc... I can't seem to find any literature on it. Can someone point me in the correct direction?

Or, if there is not an literature, perhaps answering the following question would work out too.

Ideally, I'd like Xbian to back up each night at say, 00:00. I'd like the destination of the backup to be on my NAS. Is this doable?

If not, is there an addon that would do this for me? I just want the backup so that in the event of an SD card failure, I can resume, business as usual without having to redo everything.

Thanks!

oops - I'm on beta 2 by the way.
