Enable disaster recovery for an existing Azure Notification Hubs namespace

This article shows how to enable disaster recovery or change the disaster recovery region for an existing Azure Notification Hubs namespace by using the Azure portal.

For reliability concepts, including availability zones and region-wide failure guidance, see Reliability in Azure Notification Hubs.

Prerequisites

• An existing Azure Notification Hubs namespace.
• Access to the Azure portal with permission to update the namespace.

Enable disaster recovery on an existing namespace

1. Sign in to the Azure portal.

2. Open any notification hub in the target Azure Notification Hubs namespace. The disaster recovery setting is configured from the hub, but it applies to the entire namespace.

3. In the resource menu, select Overview.

4. Select Recovery region.

5. On the Edit Disaster Recovery pane, select Enable disaster recovery.

6. Choose one of these options for the region you want to use for disaster recovery:

   • Paired recovery region
   • Flexible recovery region

7. If you selected Flexible recovery region, select a recovery region from the list.

8. Select Save.

Verify your configuration

When the update finishes:

• Check that disaster recovery is enabled.
• Check that the selected recovery region appears in the hub's settings.

Important considerations

• Disaster recovery for Azure Notification Hubs replicates namespace metadata. It doesn't replicate registration data.
• Microsoft manages the failover process.
• Your primary region and current platform support determine the recovery region options.

Next steps

• Review Reliability in Azure Notification Hubs.
• If needed, review the namespace creation steps in Create an Azure notification hub in the Azure portal.
