By simultaneous, you mean at same hour (example). Not running a SQL and Hyperv. They can be done at different hours.

Yes, thats great.

But, if the CBB HyperV product is running a VM backup on the SQL VM, isn't that bad. I basically would have two products backing up the HyperV VM with SQL. I am assuming that you want me to put in an exclusion in the HyperV routine backup that excludes backing up of the SQL in the VM.
