Can I suggest you investigate rsync ? It will allow you to replicate
file trees pretty much on demand across a LAN or indeed the internet
should you choose to. Works over SSH so it's nice and secure and if you
need virtually instant replication you could conceivably run this from a
cron job every N minutes.

/usr/ports/net/rsync
