Cloud Disaster Recovery (Cloud DR) is a process that provides cloud based / hosted disaster recovery infrastructure, solutions and service. It enables storing, managing and restoring backup data from a cloud based data backup or disaster recovery site. It is similar to traditional disaster recovery process and provides backup of client & server systems, system images, recovery time objectives, recovery point objectives and other standard DR processes.
The cloud service model for disaster recovery is known as Disaster Recovery as a Service (DRaaS)
Brief Description of Cloud Disaster Recovery
Cloud Disaster Recovery usually works through a client/server end application, which backs up the system/ server/ data to a cloud backup storage infrastructure. The backup process can be routine or scheduled. At time of onsite system failure or DR need, the data or system images can be restored and copied to any physical or virtual machine.
Typically, the recovery and restoration process is also tied up with virtual / hosted/ cloud desktops or servers. The data or system images are copied on to the cloud desktops/ servers until the primary / on premises site is recovered or reinstated.
Besides physical/ on premise system and infrastructure, cloud DR can also be used and implemented for virtualization / cloud infrastructures to provides DR services for virtual machines / servers.
