Script: Traditional disaster recovery plans depend on a very complex set of processes and infrastructure: duplicate datacenters, duplicate server infrastructure, processes for getting data to a recovery site, processes for restarting servers, processes for reinstalling operating systems, and so on. Because disaster recovery can be some complex, organizations often find themselves unable to provide good protection to more than a privileged few of their production workloads, leaving other workloads (e.g. file/print servers, internal web servers, departmental applications) unprotected or poorly protected. Because of the complexity of disaster recovery plans and infrastructure, organizations are heavily dependent on significant amounts of personnel training, on the accuracy and completeness of thick paper “runbooks” that document the recovery process, and on perfect execution of the recovery process when an outage does occur. Because testing is disruptive and expensive, organizations have a limited ability to ensure that all of their training, documentation, and execution is practiced and can successful recover their IT services. As a result of these challenges, tests of recovery plans often fail; basic recovery of critical workloads – if successful at all – often takes days or weeks; and a significant amount of IT time and resources are consumed by managing and maintaining recovery plans. In short, most firms fail to meet the continuity requirements set by their organizations. *
