  Today, the importance of having 100% uptime for businesses and industries is
clear: financial reasons and often strict government regulations for certain
industries require 100% business continuity. The concept of business continuity
(BC), as Microsoft defines it: the ability of an organization to continue to
function even after a disastrous event, accomplished through the deployment of
redundant hardware and software, the use of fault tolerant systems, as well as
a solid backup and recovery strategy, directly relates to an organization s
ability to quickly restore and deploy IT backups and business operations in a
short period of time.
