If you lose mail, it's gone, no backup at all. What if: 1) You sell commercial feed services, so the news has to be reliable? If you loase your feed data, so does everyone down stream from you. 2) You sell posting services (as an ISP)? If your crash occurs before the feed distribution, but after an article has been posted, your customer's article is lost.
