Not very long ago disaster recovery was a luxury afforded by only the very large companies due to the prohibitive cost and effort required. Frequently even these large companies were unable to justify the investment and went without a disaster recovery plan. Today, virtualization and cloud enables companies of all sizes to implement a scalable, highly efficient disaster recovery plan without a huge investment.
COSTLY AND RESOURCE-INTENSIVE DISASTER RECOVERY OF YESTERDAY
At one time, investment in disaster recovery came in one of two forms: build a replica or subset of the production- computing environment at a secondary site or contract with a disaster recovery provider. These disaster recovery providers maintained data centers equipped with compatible computing platforms upon which a company could restore their environments when a disaster was declared. The latter was often the more feasible solution since the service provider was able to leverage their hardware investment over a pool of customers thereby lowering their per unit cost and passing some of the savings along to their customers. Though, I have heard many companies complain over their $50,000-$400,000 monthly costs to maintain their contract for a secondary site disaster recovery location. These exorbitant fees did not even cover the customer’s annual testing costs to simulate a disaster and test their recovery process that often included IT staff members rolling through airports with cases of backup tapes.
