I suggest you setup that environment and test for the performance and
report if you have issues.
Please note that currently there is no data locality guarantee, so a VM
might be running on a host that doesn't have its disks.

We have APIs to do backup\restore and that is the only supported option for
backup:
https://www.ovirt.org/develop/release-management/features/storage/backup-restore-api-integration/
You can look at the Gluster DR option that was posted a while back, you can
look that up.
It used geo replication and import storage domain to do the DR.
