Why not rsync from root to root?  Or use the rsync protocol (not over
ssh).  Note that you can use -H with ssh just as well; running "over
ssh" just launches a pipe to rsync command over an ssh connection,
rather than connecting to an rsync daemon listening over socket.

You could do that with --exclude, but first, think about the
implications of that.  Your users could make hardlinks to system
files and those owned by other users files (which they can stat) and
that would cause rsync to avoid backing up those files (by either
name, since link count is shared between all links, of course).
