HyperReplication is the remote replication feature developed by Huawei.
The feature provides flexible and powerful data replication functions to
achieve remote data backup and recovery, continuous support for service
data, and disaster recovery (DR).
Definition
When a storage system runs block services, HyperReplication supports the following two modes:
Synchronous remote replication
In
this mode, data is synchronized in real time to achieve full protection
for data consistency, minimizing data loss in the event of a disaster.
Asynchronous remote replication
In
this mode, data is synchronized periodically to minimize service
performance deterioration caused by the latency of long-distance data
transmission.
Benefits
Benefits of the HyperReplication featureFunction | Purpose | Benefit |
|---|
Remote backup and recovery | To recover service data using backup data in the remote storage system after the service data becomes unusable. | This function prevents damage caused by data loss in the case that data at the primary site becomes unusable. |
Continuous support for services | To quickly switch service data from the primary site to the secondary site, protecting service continuity. | This function prevents damage caused by a service interruption upon a failure at the primary site. |
Disaster recovery | To recover data at the primary site using backup data at the secondary site in the event of a disaster. | This function prevents the damage caused by service data loss or a long recovery duration upon a disaster. |
