“Your plan must include details on how your DR environment will be tested, including the method and frequency of tests,” says Dave LeClair, vice president, product marketing, Unitrends, a cloud-based IT disaster recovery and continuity solution provider. “Our recent continuity survey of 900 IT admins discovered less than 40 percent of companies test their DR more frequently than once per year and 36 percent don’t test at all.
“Infrequent testing will likely result in DR environments that do not perform as required during a disaster,” he explains. “Your plan should define recovery time objective (RTO) and recovery point objective (RPO) goals per workload and validate that they can be met. Fortunately, recovery assurance technology now exists that is able to automate DR testing without disrupting production systems and can certify RTO and RPO targets are being met for 100 percent confidence in disaster recovery even for complex n-tier applications.”
Also keep in mind that “when it comes to disaster recovery, you’re only as good as your last test,” says Loring. “A testing schedule is the single most important part of any DR plan. Compare your defined RTO and RPO metrics against tested results to determine the efficacy of your plan. The more comprehensive the testing, the more successful a company will be in getting back on their feet,” he states. “We test our generators weekly to ensure their function. Always remember that failing a test is not a bad thing. It is better to find these problems early than to find them during a crisis. Decide what needs to be modified and test until you’re successful.”
And don’t forget about testing your employees. “The employees that are involved need to be well versed in the plan and be able to perform every task they are assigned to without issue,” says Ferguson. “Running simulated disasters and drills help ensure that your staff can execute the plan when an actual event occurs.”
