plans for the restoration of computing and communications services after they
have been disrupted. Disaster recovery plans focus primarily on the technical
issues involved in keeping systems up and running, such as which files to back
up and the maintenance of backup computer systems or disaster recovery
services.
For example, MasterCard maintains a duplicate computer center in Kansas
City, Missouri, to serve as an emergency backup to its primary computer center
in St. Louis. Rather than build their own backup facilities, many firms contract
with disaster recovery firms, such as Comdisco Disaster Recovery Services in
Rosemont, Illinois, and SunGard Availability Services, headquartered in Wayne,
Pennsylvania. These disaster recovery firms provide hot sites housing spare
computers at locations around the country where subscribing firms can run
their critical applications in an emergency. For example, Champion
Technologies, which supplies chemicals used in oil and gas operations, is able
to switch its enterprise systems from Houston to a SunGard hot site in
Scottsdale, Arizona, in two hours.
