SDRS Application Scenarios

Cross-region/Cross-AZ Disaster Recovery

SDRS provides host-layer disaster recovery protection for Huawei Cloud servers with an RPO of just seconds. By leveraging host-layer asynchronous replication, it offers cross-region and cross-AZ disaster recovery and keeps crash consistency for your data. If production site services fail to recover within a short period of time due to force majeure (fire and earthquake) or device faults (software and hardware damage), you can quickly recover services at the disaster recovery site with simple configurations.

Disaster Recovery Drill

Disaster recovery drills are used to simulate fault scenarios, formulate recovery plans, and verify whether the plans are applicable and effective. Services are not affected during disaster recovery drills. When a fault occurs, you can use the plans to quickly recover services, thus improving service continuity.
