Ten Commandments of Disaster and Business Continuity Management
Baseline for best practices defined in Janco's Disaster Recovery Business Continuity Template
As requirements for avoiding downtime become increasingly stringent, administrators need tools and platforms that can help them plan, design, and implement disaster recovery strategies that can meet those needs.
- Analyze single points of failure: A single point of failure in a critical component can disrupt well engineered redundancies and resilience in the rest of a system.
- Keep Updated notification trees: A cohesive communication process is required to ensure the disaster recovery business continuity plan will work.
- Be aware of current events: Understand what is happening around the enterprise - know if there is a chance for weather, sporting or political event that can impact the enterprise's operations.
- Plan for worst-case scenarios: Downtime can have many causes, including operator error, component failure, software failure, and planned downtime as well as building- or city-level disasters. Organizations should be sure that their disaster recovery plans account for even worst-case scenarios.
- Clearly document recovery processes: Documentation is critical to the success of a disaster recovery program. Organizations should write and maintain clear, concise, detailed steps for failover so that secondary staff members can manage a failover should primary staff members be unavailable.
- Centralize information - Have a printed copy available: In a crisis situation, a timely response can be critical. Centralizing disaster recovery information in one place, such as a Microsoft Office SharePoint® system or portal, helps avoid the need to hunt for documentation, which can compound a crisis.
- Create test plans and scripts: Test plans and scripts should be created and followed step-by-step to help ensure accurate testing. These plans and scripts should include integration testing - silo testing alone does not accurately reflect multiple applications going down simultaneously.
- Retest regularly: Organizations should take advantages of opportunities for disaster recovery testing such as new releases, code changes, or upgrades. At a minimum, each application should be retested every year.
- Perform comprehensive recovery and business continuity test: Organizations should practice their master recovery plans, not just application failover. For example, staff members need to know where to report if a disaster occurs, critical conference bridges should be set up in advance, a command center should be identified, and secondary staff resources should be assigned in case the event stretches over multiple days. In environments with many applications, IT staff should be aware of which applications should be recovered first and in what order. The plan should not assume that there will be enough resources to bring everything back up at the same time.
- Define metrics and create score cards: Organizations should maintain scorecards on the disaster recovery compliance of each application, as well as who is testing and when. Maintaining scorecards generally helps increase audit scores.
