I know Cinder can backup volumes that are not in use (at least in Juno, that may have changed in Kilo).   I am looking for an image backup solution that allow the backup of online KVM VMs.  Integration with OpenStack would be nice but isn't a must.

Well outside OpenStack it rather depends on your backend...

I'm not actually doing this so take it for what it's worth, but a
possible workflow in OpenStack would be to create a Cinder 'snapshot'
this does work live though anything you do live has some possibility
of inconsistency, you'll get a copy that will seem 'crashed' similar
to recovering from a sudden power failure.

Obviously snapshot is different than backup, so potentially you could
make the snapshot into a full volume, which would be a detached copy,
and use that as the backup source...

It's a thought any way,
