This issue has already been fixed by - https://gerrit.ovirt.org/#/c/ovirt-engine/+/116948/. Already available in 4.4.9.
Version: ovirt-engine-4.4.9.4-0.1.el8ev.noarch vdsm-4.40.90.4-1.el8ev.x86_64 Verification steps: I did the flow mentioned by Yury.Panchenko with an ISCSI storage domain. Verification conclusions: The expected output matched the actual output. The backup failed in cases the storage domain didn't have enough free space for the backup operation. The VM never got stuck in a backup state (the backup simply failed). Bug verified.
