I have a VM with 2 disk running a linux guest. Disk-1 is set to not backup.
Inside the VM, disk-0 is the sda (root filesystem) and disk-1 is sdb (mounted on /cloud).
Disk-0 is only using 17G of space.
When I run a VM backup using the GUI, the size of the backup (100GB) implies it is backing up both disk (and maybe something else). Below is the log from the backup job.
Would appreciate any insight as to what I am missing or misunderstanding.
