environment. As with hot sites and cold sites, warm sites may also be
               obtained on a shared facility basis. If you choose this option, be sure

               that you have a “no lockout” policy written into your contract
               guaranteeing you the use of an appropriate facility even during a
               period of high demand. It’s a good idea to take this concept one step
               further and physically inspect the facilities and the contractor’s
               operational plan to reassure yourself that the facility will indeed be
               able to back up the “no lockout” guarantee should push ever come to
               shove.



               Mobile Sites

               Mobile sites are nonmainstream alternatives to traditional recovery
               sites. They typically consist of self-contained trailers or other easily
               relocated units. These sites include all the environmental control
               systems necessary to maintain a safe computing environment. Larger
               corporations sometimes maintain these sites on a “fly-away” basis,
               ready to deploy them to any operating location around the world via

               air, rail, sea, or surface transportation. Smaller firms might contract
               with a mobile site vendor in their local area to provide these services
               on an as-needed basis.



                          If your disaster recovery plan depends on a workgroup


                  recovery strategy, mobile sites are an excellent way to implement
                  that approach. They are often large enough to accommodate entire
                  (small!) workgroups.



               Mobile sites are usually configured as cold sites or warm sites,
               depending on the disaster recovery plan they are designed to support.
               It is also possible to configure a mobile site as a hot site, but this is

               unusual because you seldom know in advance where a mobile site will
               need to be deployed.
