I try to change it and see what happens.

May you explain that better?
I think cluster snapshot is very efficient in terms of used space.

About performance I also noticed it's very slow (the first run much more
than the others).
Something like 5-6 M/s.
The upside of this is that you can run it any time without impacting
cluster performance.

Restore is also very slow.
This may be a major problem if I have to restore terabytes of data.

But as of now I'm focusing on the space efficiency and the possibility to
restore single disks (not tested yet becuse of the problem I noticed now).
