Disaster Recovery Using Virtual Machines
  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.
