To create a successful IT disaster recovery plan, all stakeholders must be on the same page. Business owners, security experts, and IT leaders should collaborate with each other to determine how to best:protect your datarecover your systems and infrastructuremanage the people and processes who will execute your recovery at time of disasterTo create an optimized IT disaster recovery plan, you should: Perform a business impact analysis (BIA) - A BIA will identify the most crucial systems and processes for the business and the impact an outage would have on the business. It also offers a clear picture of the vulnerabilities in the system and the time it will take to recover from an outage. Based on the result, you can prioritize the recovery effort. A business impact analysis will help you define the Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) for your critical applications. Determine application interdependencies - You need to tier your applications according to their impact on the business. Once you do this, you will see that many of your business-critical applications contain interdependencies with less critical applications. That means restoring a critical application might require that lower tier applications are also restored at the same time. Engage in disaster recovery testing - Once the plan is in place, it needs to be exercised regularly. Any areas of improvement should be integrated into your ongoing disaster recovery program in a focused way. Ensure effective change management - Your production environment undergoes daily changes that can cause it to diverge greatly from your recovery environment over time. This can cause significant recovery problems if not managed correctly.
