Hi,

I have noticed that PBS is doing full backups and the saves only the delta for the VMs that are not running.

Is this the expected behaviour?

Thanks.

That is expected. When VMs are shut down the qemu process is closed. The qemu process is the one tracking your changes in the blocks of the disk.

It will need to read the entire disk again, but it will only transfer missing chunks (as you already said). The Proxmox Team said they want to think about ways of doing this better in the future, but for now thats how it works.

Hi, an idea would be that powered vms should be backed up after running vms.
