I am having an issue backing up vms using the backup_vm.py example script. The error I get is below:

[   0.0 ] Starting full backup for VM 'c656db00-065c-4fd0-b8b9-74a86dc864fc'

ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Cannot backup VM. Host (vsh001) is running on a version lower than 4.4.5. Please upgrade the host in order to use incremental backup.]". HTTP response code is 409.

The strange this is that I am running oVirt 4.4.7. What component is it complaining about that is not  up to version needed? Any help on this would be appreciated. oVirt rpm is ovirt-host-4.4.7-1.el8.x86_64. I plan on upgrading to version 4.4.10 but want to get this fixed first. I also can't got to 4.5.x because I have problems with Windows 10 vms and vGPUs.

Thanks
