Let me add this, as I don't think most people would pro-actively look for this until AFTER, they had a problem of extended down time.
If you had a client who's MAS90 database got blown away due to human error, hard disk crash, or flood, and it took say many days or weeks to get back up (even if significant data wasn't lost), and it was an 'excruciating' experience to go through, what would you search for?
