Hi,

thank you for your suggestion.

Rsync will copy the whole file new, if the size is different.

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.

Something like lvmsync ( which is just working with LVM ).

So i am looking for a tool which can do that on a file-base level.


Have you tried rsync --inplace? It works quite well for us, no whole file copying. We use ir for raw VM disc files.
