what licenses do I need for B&R? It's liensed for backed up (protected) hypervisors, for each cpu socket. If I'm using it only as backup target than how do I pay for it?
For your scenario Veeam B&R license is not required. You need VAW license with workstation and server counters inside. Such license can be installed in Veeam B&R FREE and you can use it as a target. Check out VAW BETA
with license include in the package.
