You can try to use the "-y" or "--fuzzy" option to rsync (at least
rsync 3) to implement this.

Quoting from the man page: "-y, --fuzzy: This option tells rsync that
it should look for a basis file for any destination file that  is
missing. The current algorithm looks in the same directory as the
destination file for either a file that has an identical size and
modified-time, or a similarly-named file. If found, rsync uses the
fuzzy basis file to try to speed up the transfer."

HTH,
Filipe
