Round-Robin Director Backends

I have an environment with multiple backend servers that require most images (static content) be replicated out to all servers, this is causing unnecessary load on our backend servers. To mitigate this problem we plan to put in a Varnish system to grab the assets from the backend servers and send them to the client VIA a round-robin director.

If Varnish cannot find the asset on the current backend server does it automatically go to the next backend in the list? If not what VCL code do we need to insert to accomplish this?
