As far as I know, it is not possible, to mount an encrypted partition at all.

Hmm, not quite sure, what you asked, but as far as I know, rsync does not 
care, if the files or filesystems are encrypted or not. It just copies the 
stuff to the target byte by byte. If there is something overwritten or not 
readable / writable depends of your normal access rights.

Or am I wrong???
