DU and hard links

I have a series of backup home directories what use hardlinks on files
that have not changed.   If I run "du" on these directories I get
a disk usage summery as if the directories are not hard linked together!

How can I get real disk usage summery.  IE: the cost in disk space of
the second and later directories without re-counting files already seen
due to hard links!!!
