Since root can't write to NFS mounted file systems you need to have
your accounts on the NFS server available to the NFS client. I did
this through NIS (yp). Your NFS server is also the NIS server.
Whatever accounts you have on the server can also logon to the client
getting its authenication information from the server. Then if you
export a directory called /export/backup which has permissions 775 and
owned by root:users an all your accounts are in group users. When you
logon to the client as a users that account will be able to write to
the remote mounted file system from the server. Oh, you have to mount
server:/export/backup to some directory on the client as root. You
might want to look into the auto mounting features.

Here are some great references to NFS and NIS and very easy to follow
with good examples.
