Please speak after me: Rsync transfers and compares file lists, therfore detects any changed, added and removed files. (Maybe only misses files which keep their size and modification time, but are modified anyway - a bad thing, IMO). The n+1-th incremental compares against the most recent n-th incremental, therefore only transfers the difference to that. But since mergine several incrementals is expensive in terms of server I/O, you may limit the number of levels.
