What are the basics of a disaster recovery plan? The best place to start with a disaster recovery strategy is to identify which systems, applications and types of data are most critical to your business operations. Risk assessments and business impact analysis will help you to simplify the process and move your DR strategy in the right direction. If you follow ISO 27001, the information security management for instance, this would be part of your business continuity planning. Your DR strategy should be a living document. Regularly review it, test it and risk assess all elements of your IT infrastructure. Don’t let a disaster affect your day-to-day business operations by being unprepared.
