Mirroring a website

I need to mirror a website.
I plan to do this on two differant servers.(serverA, serverB)

I see zoneedits failover service will do the trick ,if one server is down ,it will switch you over to a second server
With a down time of apx. 5 minutes(?)

When serverA is restored the failover reads that the 1st Ip is responding and switchs back from serverB to serverA.

I need to keep site on serveB current and it contains phpBB and php files,MySQL,ect.
How about email service?

How can I keep site current?
Run Cron job and zip database?(I dont know I am just guessing here)
any help would be thankfully received!
