Where 873 fits
Why 873 is special
rsync compares source and destination and transfers just the differing blocks, which is why mirroring a large archive over a slow link is feasible at all. Most Linux distribution mirrors are still kept in step this way.

rsync transfers only what has changed and Subversion tracked changes centrally. Both are answers to the same question — how to move a large body of files without moving all of it — from different directions.
