the simple and low-end way is if you use rsync or something like that to 
synchronize the data on both servers, and keep the data on both servers 
local. Use one of them as master (writable for your staff) and the other 
one as read-only slave.

the high-end (high budget) way of doing this is to use storage that can 
be shared between multiple servers (for example a SAS or SCSI connected 
box) and use a cluster filesystem such as GFS or OCFS2 (and ideally use 
samba CTDB, then you have a real high performance, high availability 
samba cluster).
