rsync is something like that and very effective.
from the man page :
The rsync remote-update protocol allows rsync to transfer
just the differences between two sets of files across the
network link, using an efficient checksum-search algorithm
described in the technical report that accompanies this
package.
the technical report included in the debian package explains it all.
hope that helps.
