Ugh. What a week!
Anyway, my situation is that we have a production server in San Fransisco, and
a "hot" backup in my hometown (Chico, CA) .
What I'd like to do is mirror the production server to the local one, so that
if the SF server goes down, we have work saved to the last possible moment.
Say, within 10 minutes.... Is this feasible?
Thanks,
