That's what VEPA Backup is also doing and is widely used in the Enterprise.
It depends of the type of storage you use. For example , file-based storage (NFS, Gluster) is easy - you can just copy the snapshot and then delete.

Yet , for block-based storage the only working solution I have seen to be working properly is the snapshot (VEPA backup) or it's clone to be presented to a VM for accessing it.
I don't know about this vProtect , but ssh cannot be faster than a tar over a tape or other media.

Of course, storage-based snapshots are the fastest , but they also require space.

The biggest problem with these tools is that they are very inefficient.  To work they snapshot the VM then clone the snapshot into a new VM, back it up then delete.  This takes a lot of space and time. 

vProtect and some other enterprise backup software snapshot the VM and stream the snapshot from the API without needing to clone or using a proxy VM.  The new version of vProtect even bypasses the API (because it's slow) and now supports streaming over SSH directly from the host.  This is the ideal solution for oVirt VM backups imo, but I don't know if any free tool exists that can offer the same functionality.

I am still using https://github.com/wefixit-AT/oVirtBackup but since
support for the v3 API will be removed with oVirt 4.4 it will stop
working with this release. For this reason I can no longer recommend it
but it served me well the past few years.

There is also https://github.com/jb-alvarado/ovirt-vm-backup which has
similar functionality but I have yet no first-hand experience with this.

Hope this helps.
