I'm repeating myself ;-) : ONLY FOR NON-RSYNC-TRANSFERS!
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.

HTH,

Tino.
