Hello, While trying to backup stopped VM (with POST on /ovirt-engine/api/vms/b79b34c0-d8db-43e5-916e-5528ff7bcfbe/backups) I got the response:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>[Cannot backup VM. The Virtual Machine should be in Up status.]</detail> <reason>Operation Failed</reason> </fault>

Yes, this is not supported now.

I found here: https://www.ovirt.org/develop/release-management/features/storage/incrementa... that it should be possible to back up a virtual machine that is not running. "If the VM is not running, the system will create a paused, stripped-down version of the VM, with only backup disks attached, and use libvirt API to start and stop the backup."

This is a possible solution we considered, but it is not implemented yet. The next line is: Since creating special paused VM for backing up non-running VM is a lot of work, we may defer support for backing up non-running VMs. We got a request to implement this from other backup vendor, and we are discussing the possible solutions with platform folks.
