Oh, you're right, I checked the wrong thing - sorry.

If the MP is not being backed up it will fly under the radar in most situations until it is too late -> people realizing that the backup id only partial when they want to restore.

No, but that's also not really solved by the default on check box, IMO.
If you changed that once you may not remember about that the next week (or day ^^)

So, additionally to the default on (where we could see if we ensure that both
VM and CT have the same checkbox name ("Include in Backup"?) and same behavior.

Then, we could additionally add a mechanism to backup jobs to see what gets backed
up, i.e.,  the ui could be a window with the VM/CT list as tree with the disks as
tree-root children - with a symbol/text for if one disk is backed up or not, e.g.

+ VM 101 ...
`- disk scis1 - included in backup
`- disk scsi2 - excluded from backup

+ CT 102 ...
`- rootfs - included in backup
`- mp0 - included in backup
`- mp1 - excluded from backup

(as basic example for what I mean).
This way one could easily verify the VM/CTs affected by a backup job and further
see at a glance which disks are skipped or not.
