Yes, all files with duplicate content are linked to a common pooled copy
regardless of where they were found. It doesn't matter whether or not
they were on the same target - you'd also get the same effect from
backing up the clients individually. The files will all be copied over
the first time even with rsync but the duplicates won't take additional
storage space.
