Best WWW server setup?

I have been doing research for a very long time and am finding it 
difficult to initiate success.

I have installed OpenBSD and I want to use the drive as a webserver. 
But I am stuck and don't know where to go from there.  It has 2 ethernet 
cards and 2 harddrives.

I want to use one drive to serve web pages and the other as a backup for 
my OSX lap machine.

I don't know the commands to communicate between my lap machine and the 
server.  I don't know how to use the second drive of the server to 
backup the laptop.

I have search many many months via google.  But my search techniques are 
poor (not sure where to look, not sure the proper search strings to use) 
  and google always gives me blind leads; I just see the same ones over 
and over.

Thank you in advance.
