Performing a Reverse Reprotection

Scenarios

After a planned failover, data is not automatically synchronized from the disaster recovery site to the production site, and protection is disabled for protected instances. To start data synchronization from the disaster recovery site to the production site, perform a reverse reprotection.

After a reverse reprotection, initial data synchronization starts. During this process, if disaster recovery site servers are restarted, data will be resynchronized until the synchronization is complete.
After a reverse reprotection is complete, if disaster recovery site servers are restarted, data will not be resynchronized. If data is then written to the disaster recovery site servers, the incremental data is then synchronized.

Prerequisites

Disaster recovery site servers have been preconfigured according to Configuring Disaster Recovery Site Servers.
The status of protected instances in the protection group is Planned failover completed or Reverse reprotection failed.
