Introduction to local recovery supported by the OceanStor ReplicationDirector

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.

If data or applications at a production site become unavailable due to disasters or faults, you need to recover data from a disaster recovery site. Fault recovery is performed only in the disaster recovery management system at the disaster recovery site. The latest backup data at the disaster recovery site is used to recover data.

The OceanStor ReplicationDirector (mainstream version: V100R003C10) supports local protection and recovery. The OceanStor ReplicationDirector manages snapshot-based local recovery plans and provides local backup and protection for various applications.

Recovery plans refer to the service objects to be recovered in the disaster recovery management system. Users can perform disaster recovery operations for recovery plans, such as testing, clearance, planned migration, reprotection, and fault recovery.

In OceanStor ReplicationDirector remote recovery, a remote recovery plan is executed to perform planned migration or fault recovery, based on the policy template for remote recovery protection.
