Just in case people don't misunderstand the use of the word diff here,
I don't think that will copy only the differences. It will copy the
changed files.  If that's what the original poster wanted, OK.

If you want just the changed bits of files, and not the whole files, I
think you should look at the rdiff-backup program, which does keep the
differences between editions in separate files.
