Only files that have changed between A and B will be copied, yet you
will have two directories, one with the state of things from date A,
the other with the state of things from date B.  Files no longer in
existence at date B will be deleted in the B directory, but since
they are hardlinked they will still exist in the A directory.

I think this is exactly what you're looking for, based on your letter,
but I'm probably missing something too :)
