I am getting some emails from the server:
10min disk backlog (was critical for 13 minutes)
I need to fix it.
The backups have to be sent to other server, used to go well.
Regarding the backups, that are container snap backup. Disks backups are in the Volumes directory, each disk has individual backup.
Also instance backup is disabled in server end due to that readonly issue.
Create a instance with a full Kali Linux.
