Testing Your Disaster Recovery Plan

If you have a fire alarm in your home, you should test it on a regular basis to minimize the opportunity for disaster. Similarly, most small to mid-sized enterprises should have some type of DR (disaster recovery) plan in place. However, few actually ever test the plan, let alone test it on a regular basis. So what goes into a DR plan test? Is it important to test every portion of the plan? If so, how is this done?

McFarland says for SMEs, DR plan tests typically begin with component and subsystem tests and then build up to full-scale system tests in a live operational environment. “Since these tests can be disruptive to business operations,” he says, “companies are increasingly relying on lab testing with network emulators to conduct rigorous and realistic tests prior to the full-scale deployment and testing in the production environment.”

According to Bruce McFarland, director of marketing at Anue Systems, lab testing with a network emulator enables companies to repeatedly subject network applications, DR systems, and processes to the requirements and impairments of a real-world network environment. He says, “With this rigorous and authentic testing in the lab, full-scale system tests in the production environment can be done less frequently. Most network application and DR plan testing can be done without the expense of replicating the corporate network and without disruption to the production IT environment.” On top of this, McFarland says a robust test plan also needs to include tuning and debugging of issues that arise during the test.
