I am a little surprised about your common sense for the data protection. obviously, you never heard of data center on fire that wipes out all servers or all servers were down for 3 or more days. Just a quick google search and there are so many data centers related issue reported in the past. http://www.thetechherald.com/article.php/200823/1124/The-Planet-Outage-%E2%80%93-H1-Datacenter-suffers-fire-and-explosion-Update-1 http://www.techflash.com/seattle/2009/07/Why_the_Seattle_data_center_fire_caught_companies_unprepared49978502.html http://www.datacenterknowledge.com/archives/2008/03/31/fire-destroys-wisconsin-data-center/ http://www.intology.com/computers-internet/us-data-center-catches-fire-9000-servers-down/ http://www.prisontalk.com/forums/showthread.php?t=340505 anyway, thanks for your other suggestions.
