But where is the sense then in using rsync? The following applies to rsync only! The difference between a full and an incremental rsync backup is that rsync will check the whole file checksum during full backup (to guard against pool file corruption). It will not transfer the whole file. The incremental backup will transfer all differences since the last full or incremental (depending on incremental level). > Or is it the way the backup is stored? A full backup will have a fully populated directory structure on the server (with hardlinks to the common pool) while an incremental backup only has the directories and any changed files (again hardlinked to the common pool). To sum it up: There are subtle differences in transfer (only for safety reasons) and major differences in storage.
