network groups

[Rolf Wilson]

   I have a near-beginner question about using netgroups.

I have 2 machines, "alpha" and "beta". I have a tape unit
on alpha that needs to back up files from a disk on beta.
The disk in question is NFS mounted. Each machine is listed
int the /etc/hosts.equiv file of the other. I have been told
that I can use the /etc/netgroup file to set up a file that
would allow what I want, which is to have root on machine
alpha be able to be in a group such that it can access
files on the disk on beta. 
   I have read the manual, and was unenlightened. A local
expert has tried to help, but no luck so far. A brief
example would be wonderful. What do I need to put in
the /etc/group and /etc/netgroup files on the 2 machines
to let user root on machine alpha access files on machine
beta with access -rwxrwxr-- and group ownership netgroup1?

Thank you very much for your help.
