Advantages

Advantages

Storage-based Replication

Synchronous replication (RPO = 0) and asynchronous replication (minimum replication period: five minutes) are supported. The replication process does not affect the computing performance of the ECS.

Data Consistency

Tenants can perform consistency replication DR protection for all volumes of one or a group of ECSs.

Transparent to Applications

This solution provides cross-site remote replication based on IaaS for the storage layer and administrators do not need to know about DR capabilities of applications in VMs.

DR Testing

Tenants can perform DR tests to check whether services on the DR ECS can be restored. The test does not affect production VMs.

Simple DR Management

DR administrators can perform fault recovery, reprotection, and planned migration for ECS protection instances.

Mutual DR of Two Data Centers

The ECS in either data center can be protected by the other data center.
