One of the main selling points for implementing a storage area network (SAN) are all of the disaster recovery features one provides. In this lesson, Christopher Poelker delineates considerations for building a basic disaster recovery plan. This lesson answers the questions: How much data do I need to copy? What can I afford to lose? How do latency and bandwidth play into faster backups and restores? Some other topics covered: recovery time vs. recovery point objectives; choosing a remote site and its components; and creating the final plan according to budget.
