How about speed performance (64K,4MB) and stability vs proxmox vma format ?
I'm curious, because I still fear to use proxmox feature when I see all the
stability bugs reports on the forum.
And I would like to test incremental backup too. (only full backup is not
possible for me)

We're currently implementing our own backup system which uses the
drive-backup qmp routine to dump qcow2. We don't need the config files.
And this works with ceph and 4MB cluster size.
