Since we talk about raw image files of virtual servers, rsync is no option. We need something which will inside of a file just copy the delta's.

It works quite well for us, no whole file copying. We use ir for raw VM disc files. -- Zuzendari Teknikoa / Director Técnico Binovo IT Human Project, S.L.
