By using Amazon VPC for disaster recovery, you can have all the benefits of a disaster recovery site at a fraction of the cost. You can periodically backup critical data from your datacenter to a small number of Amazon EC2 instances with Amazon Elastic Block Store (EBS) volumes, or import your virtual machine images to Amazon EC2. To ensure business continuity, you can quickly launch replacement compute capacity in AWS. When the disaster is over, you can send your mission critical data back to your datacenter and terminate the Amazon EC2 instances that you no longer need.
