[SOLVED] VM backup excluding disk not working

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.

Code:

Would appreciate any insight as to what I am missing or misunderstanding.
 
Trimming too often is not good for the life of flash memory.

Debian based systems trim automatically (cron) once a week, in the night from sunday to monday.
 
On my ubuntu system, looks like it's running weekly. I made a big change a few days ago and it just hadn't run since which is why I was seeing the large file size on the backup. Should be good to go now. Thanks for the assistance.
