I had corruption of the Hosted Engine due to a power failiure of all hosts (Gluster). My lab has no UPS.
You can create a snapshot via API , backup the snapshot and then delete it via the API while the VM is working (no downtime). Still, this approach won't work for Databases as you can create the snapahot in the middle of a transaction.
