The Geo-Disaster recovery feature ensures that the entire configuration of a namespace (Event Hubs, Consumer Groups and settings) is continuously replicated from a primary namespace to a secondary namespace when paired, and it allows you to initiate a once-only failover move from the primary to the secondary at any time. The failover move will re-point the chosen alias name for the namespace to the secondary namespace and then break the pairing. The failover is nearly instantaneous once initiated.

Unless the disaster caused the loss of all zones, the event data that is preserved in the primary Event Hub after failover will be recoverable and the historic events can be obtained from there once access is restored. For replicating event data and operating corresponding namespaces in active/active configurations to cope with outages and disasters, don't lean on this Geo-disaster recovery feature set, but follow the [replication guidance](event-hubs-federation-overview.md).

> The feature enables instant continuity of operations with the same configuration, but **doesn't replicate the messages held in queues or topic subscriptions or dead-letter queues**. To preserve queue semantics, such a replication will require not only the replication of message data, but of every state change in the broker. For most Service Bus namespaces, the required replication traffic would far exceed the application traffic and with high-throughput queues, most messages would still replicate to the secondary while they are already being deleted from the primary, causing excessively wasteful traffic. For high-latency replication routes, which applies to many pairings you would choose for Geo-disaster recovery, it might also be impossible for the replication traffic to sustainably keep up with the application traffic due to latency-induced throttling effects.
