You've moved your disaster recovery operation to the cloud and now it's time to test it. That's essential because it's the only way to guarantee your plan works and that you can recover critical data after a disruption. Plus, testing allows you to train staff, perform maintenance, engage your business users and suppliers, and make your organization aware of disaster recovery (DR) procedures. Not testing can cause your plan to fail even before an incident. (Still, according to research from the Disaster Recovery and Preparedness Council, nearly one in four companies never test their DR plans.) Cloud testing differs from traditional assessment. Gone is the need to send tapes and testers or break the link on your replicated disk. With disaster recovery as a service (DRaaS), you can start your cloud test at 8 a.m., begin user testing at noon, and complete the entire process by 4 p.m.
