Step-by-step explanation:
The cloud service that can be recovered after a failure is known as Disaster Recovery as a Service (DRaaS). This type of cloud service specifically provides organizations with the ability to continue operation by replicating and hosting physical or virtual servers to a second location which can be accessed in the event of a primary site failure. Utilizing DRaaS, businesses ensure their critical data and applications are protected and can be promptly restored after a disaster, such as a natural disaster, cyber-attack, or hardware failure.
