Introduction to OceanStor ReplicationDirector in the local protection disaster recovery solution
The local protection disaster recovery solution uses snapshot technology to ensure local availability of host services. This solution can use VIS snapshots of protected objects to roll back data, preventing data loss and virus attacks. The OceanStor ReplicationDirector Server is installed on the DR management host deployed in the production center and the OceanStor ReplicationDirector Agent is installed on production application hosts to ensure DR data consistency. This solution supports the snapshot (array and VIS) technology.

Deployment of OceanStor ReplicationDirector in the disaster recovery data center solution (geo-redundant mode)
OceanStor ReplicationDirector (current major version: V100R003C10) is deployed in the disaster recovery data center solution (geo-redundant mode) in the following manner: 1. You can deploy one piece of OceanStor ReplicationDirector in one data center to centrally manage the local production center, local disaster recovery center, and remote disaster recovery center, or you can deploy one at the local disaster recovery center and one at the remote disaster recovery center to achieve disaster recovery management. 2.
