rsync $OPTIONS --link-dest=$YESTERDAY  $WHAT $TODAY

But it would probably be easier to use any of the several existing scripts 
that handle that situation nicely.

        rdiff-backup    the previous backups are stored as rdifs.
                        I think it will go very slow over USB.

        rsnapshot       rsync style.
