Performing a failback

Failback is the act of redirecting traffic from your recovery system to your primary system. This is an operation that is performed outside of Elastic Disaster Recovery. Elastic Disaster Recovery aids you in performing the failback by ensuring that the state of your primary system is up to date with the state of your recovery system.

Before performing a failback, you want to make sure that any data that was written to your failover systems during the failover is replicated back to your original systems before you perform the actual failback and redirecting users to your primary systems. Elastic Disaster Recovery helps you prepare for failback by replicating the data from your Recovery instances on AWS back to your source servers with the aid of the Failback Client.
