But I thought rsync will always copy the complete file, not just the differences. So the checksums are for the complete file, and if the complete file checksum doesn't match, the complete file is transferred. That isn't whats desired here, just the differences WITHIN a file.
If my understanding is wrong and rsync does have the proper magic to copy just the differences within a file then rsync is even cooler than I thought.
