Can you discuss the key elements of an effective disaster recovery plan?

One of the major responsibilities of a systems engineer is to create, test, and, if necessary, execute a data recovery plan. This involves developing and deploying redundant systems designed to survive scenarios like natural disasters and power failures. As a systems engineer, you should have experience in this and discuss your experience on similar projects. The interviewer is expecting to hear that you have created or managed disaster recovery plans that address the organization's physical and electronic assets and can deliver services in the event of losing access to some of the IT assets you manage.
