I could be wrong but i believe you need to push libvirt / qemu to a
newer release on your hosts to enable the feature. This may be a 4.3
only thing though.

Thank you!
We will be glad to have some feedback when you have some.
Please keep posted.
Just the first steps.
I enabled in engine the incremental backup feature and restarted
engine service.
Created a CentOS 8.1 VM to backup, and updated it.
It has one qcow2 disk with flag of incremental backup enabled.
I configured another server to be sort of backup server.
Installed CentOS 8.1 + updates, then
dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
dnf update
dnf install python3-ovirt-engine-sdk4
dnf install ovirt-imageio-client
Copied backup_vm.py from the examples directory to the /root and tried
a full backup
[root@c8-bck-server ~]# ./backup_vm.py full --engine-url
https://ovirteng.mydomain --username admin@internal -c ca.pem
--backup-dir /backup 80fd995d-63c7-4f2a-a4c2-0ddaf1a8389d

What is the problem with the host?
Thanks,
