OK.

Yes, there are replica of other VMs, but not this specific VM under backup.

Anyway, yes: on the same note there's a backup and a replica. Effectively
when i reboot the node, i receive two errors of failed replicas from the 2
VMs on the other node, that was stalled.

I've tried to split backup job and limit (a little) the bandwidth, but
problem persist.

Now i've tried to change backup mode from snapshot to poweroff: the VM under
backup is a 'scratch' one and can be safely rebooted.


I come back with more info. Thanks.
