About This Document

Storage Disaster Recovery Service (SDRS) provides disaster recovery (DR) services for many cloud services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), and Dedicated Distributed Storage Service (DSS). SDRS uses multiple technologies, such as storage replication, data redundancy, and cache acceleration, to provide you with high data reliability and service continuity.

SDRS protects service applications by replicating the server data and configurations to a DR site. It allows service applications to start at the DR site in the event that the server at the production site stops. This improves service availability and continuity.
