But this is not an easy task - also you need such a storage. Generally i
think something like a clustered leightweight database would be much
better instead of an FS for stuff like that.

But this is out of my knowledge and something more longterm may be PVE 4?

So i would like to implement something pretty simple f.e. rsync?
