[sheepdog-users] Cluster Snapshot and automatic vdi snapshot

I wish to know also other user opinion, so I opened this tread.

Mmmm...I'm struggled about that.
It probably depends on how the user uses the cluster.

When I run 'cluster snapshot save' I usually aim to save the whole
cluster content as it is "now".
If there's a vdi I don't wish to backup, I may delete it before the snapshot.

>From the other side,  there may be some vdi I wish to keep but not
include in the 'cluster snapshot'. (I think that's less probable
tough).

Is anybody thinking of other rational in not automatically saving vdi with id0?
