Yes, that works. I know companys running that configuration. Take the latest
8.0.1 (8 SP1) for the client.
Configure the ports (nsrladb or nsrports) and open that ports in the
firewall.
If possible do an update to 765 on the server. Take care of authentication
error messages in the daemon.raw.
If there are a lot of messages in the daemon, this is supposed to be fixed. 
You can not operate a 8.0 NSR server with 7.6 Storage Nodes !

You will require a NetWorker 8.0 SP1 or later Windows Client which can be
used with your NetWorker Server.

Subject: [Networker] Backing up a Win2012 client to a 7.6 server ??

We need to backup a Windows 2012 64bit client. Apparently that requires NW
8.0 but our server is 7.6.4.  Will the server backup a client running NW 8
???   Has anyone done this ? Is there anything to look out for or other
config issues ?   It's located in a locked down portion of our DMZ so we
expect to request firewall ports to be opened to allow the backup ?? True ?

Thanks,
Paul
