Overview

A DR system ensures full data protection to avoid regional disasters or meet cross-cloud DR needs. In case of a site-level disaster, this system reduces data loss for the production system. It allows the DR center to quickly take over services, keeping smooth service operations and minimizing damage.

In cross-region DR, application systems can be deployed across multiple regions with data replicated among the regions. This allows for disaster recovery if a region faces service disruptions or data loss.

In cross-cloud DR, if an application system has been deployed in an IDC or other clouds, you can deploy another application system in Huawei Cloud and replicate data from the IDC or another cloud to Huawei Cloud. This enables disaster recovery if the entire IDC or cloud fails or data gets lost.
