I have been able to migrate all vms over to qcow2. Think shutting down the vms and booting backup. Alos if anything from this thread might have had an impact. https://xcp-ng.org/forum/topic/12087/backups-with-qcow2-enabled/9

holy molly, you have some good network performance !
what kind of SR at source ? and remote at destination ?
what about the PIFs ?

We might have better Ceph support in the future for large clusters.
