I think Ubuntu One is syncing my backup folder (deja-dup). I'm concerned this could be a problem should a file become corrupted, and I need to retrieve it. Is there some way I can see a list of synced folders and turn off ones I do not want? Thanks!
To view the folders Ubuntu One is syncing you need to open the Ubuntu One Control Panel. The first view you come across will be the list of folders currently being synchronised.
If you see you deja-dup backup folder in there and you want to stop it syncing, then you can do one of two things.
