Backup with very small size making it impossible to restore

[vinicius3d97]

Hi, this is my first post and I hope you're doing it right.

I have followed the backup history of some vm's that I have where the size of the snapshots follow the size of the disks that make up the machines. But I'm having problems with a backup of a specific vm that has 100gb of disk but the backup is extremely small as can be seen in the image.

I performed a test restore of a snapshot prior to a software installation and after starting the machine I noticed that there were no changes.

I even checked the backup compression type and the funny thing is that previously I was able to change between compression types but now the field is disabled.

Thanks for listening

You have excluded your harddisk from the backup (backup=0). So you probably are only backing up the config of your VM.

And how can I check and review it?
Well, I'm just having problems with this vm.

Thanks for listening.

Open the harddiskconfig (vm/hardware) and enable the backup checkbox.

Open the harddiskconfig (vm/hardware) and enable the backup checkbox.

I thought this option was related to Datacenter/Backup/Job and not the disk itself.
You helped me a lot

Thank you so much!
