For a long time I'm receiving the error "~/.cache/deja-dup/metadata could not be restored" after every backupo which is quite annoying. It seems that Deja Dup is looking for this file as kind of sanity check for this backup.
However I excluded the .cache directory. So DD will never ever find that file and warn me in all eternity. (I just included ~/.cache/deja-dup, let's see if that changes things)
(Why would you backup a cache dir anyway? see also http://askubuntu.com/questions/40992/what-files-and-directories-can-be-excluded-from-a-backup-of-the-home-directory)
If this really is a sanity check than you might look for a file which really is included.

Backing up and restoring seems to work fine, I renamed a file in my home dir and could restore it using the context menu in Nautilus.
