req.backend should be ok. I'm using

In my error-page

Varnish defaults backend is the first backend you list in your config.
If you don't set it explict it will use the default and the
req.backend will probably be "null" so my first backend is

backend unassigned {
        # Wildbill
	.host = "10.84.200.5";
        .port = "80";
}

And set it all backends expliclty in the vcl_recv.
