Created attachment 1669657 [details]
restore log

Description of problem:
Upgrading from 4.3 to 4.4 is not possible as restore will refuse to unpack the backup as it was created in 4.3.

There is no other way to upgrade so this needs to be enabled.

Version-Release number of selected component (if applicable):
ovirt-engine-tools-backup-4.4.0-0.25.master.el8ev.noarch

How reproducible:
always

Steps to Reproduce:
1. install rhel7 with 4.3
2. backup
3. install rhel8 with 4.4 repos and packages
4. restore

Actual results:
restore fails with FATAL: Backup was created by version '4.3' and can not be restored using the installed version 4.4

Expected results:
restore succeeds
