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,
