Disaster Recovery as a Service is more than just restoring corrupted data files. It is leveraging a service provider to support the DR planning, testing and execution process. This includes sending replicas of your entire production environment and replicating them in a third-party, off-site location (often the service provider’s datacenter). When one of them fails —whether from a natural disaster, hardware failure or cyber-attack — they can be turned on at the third-party location. When the primary, production datacenter is back online, you can then failback to the main production site along with any of the data changes that took place during the failover period, ensuring no data loss. It is common for the service provider to help orchestrate the failover and failback process.
