My backup strategy, is every day at 3AM, y make a tar of /var/spool/mail. and passes to another server. There is no need of having mirrors, because users knows that mail server could crash, and i will be restore on 4 hours. I make Spam filtering / AV checks, on other SMTP server, and then it passes to this server.
