(CEO) as your spokesperson during a disaster. A media liaison should
               be hired, trained, and prepared to take on this responsibility.



               Utilities

               As discussed in previous sections of this chapter, your organization is
               reliant on several utilities to provide critical elements of your
               infrastructure—electric power, water, natural gas, sewer service, and
               so on. Your disaster recovery plan should contain contact information

               and procedures to troubleshoot these services if problems arise during
               a disaster.


               Logistics and Supplies

               The logistical problems surrounding a disaster recovery operation are

               immense. You will suddenly face the problem of moving large
               numbers of people, equipment, and supplies to alternate recovery
               sites. It’s also possible that the people will be living at those sites for an
               extended period of time and that the disaster recovery team will be
               responsible for providing them with food, water, shelter, and
               appropriate facilities. Your disaster recovery plan should contain
               provisions for this type of operation if it falls within the scope of your
               expected operational needs.



               Recovery vs. Restoration

               It is sometimes useful to separate disaster recovery tasks from disaster
               restoration tasks. This is especially true when a recovery effort is
               expected to take a significant amount of time. A disaster recovery team
               may be assigned to implement and maintain operations at the

               recovery site, and a salvage team is assigned to restore the primary site
               to operational capacity. Make these allocations according to the needs
               of your organization and the types of disasters you face.




                             Recovery and restoration are separate concepts. In this

                  context, recovery involves bringing business operations and
                  processes back to a working state. Restoration involves bringing a
