Chapter 10: Disaster Recovery and Business Continuity and the Cloud

FOR YEARS, A PRIMARY job of the IT staff of an organization was to ensure availability of computing resources (applications, files, and even phone systems) not only on a day-to-day basis, but also in the event of a crisis or natural disaster. Business continuity describes the policies, procedures, and actions taken by an organization to ensure the availability of critical business functions to employees, customers, and other key stakeholders. Disaster recovery describes the steps a business will take to restore operations in the event of a disaster (fire, flood, hurricane, tornado, or other event). Following 9/11, business continuity and disaster recovery became a very real and essential IT function.
