Data Recovery

Data Recovery

If the primary site fails, the secondary site takes over its services. When the primary site recovers, it takes control of those services again.

After the primary site recovers from a disaster, it is required to rebuild a remote replication relationship between the primary and secondary storage systems. You can use the data of the secondary site to recover that of the primary site. Figure 1-5 shows how the storage system recovers data at the primary site after a disaster.

Figure 1-5 Process of recovering data at the primary site after a disaster

In asynchronous remote replication scenarios, the storage systems perform data synchronization until data differences between the primary and secondary LUNs are minimal. Then, services are stopped and the last data synchronization is executed. This prevents data loss and minimizes the service downtime.
