[olug] setting up a mirror (slave?) DNS server?

[Ryan Stille]

We currently have BIND running on one of our servers.  Its a primary 
name server for us, and a secondary for a partner of ours (and they are 
our secondary).

I'd like to setup BIND on another server here that would basically be a 
mirror of ours, ready to be used if ours fails.  Whats the best way to 
go about this?  I could FTP all the named files over once an hour or 
whatever.  But I was thinking there should be a way to use the 
master/slave functionality to have the new server just slurp all the 
data from our master server automagically?  (if thats true why do I need 
to always add my new zones to named.conf on our secondary server?)  Any 
suggestions or URLs welcome.

Thanks,
-Ryan
