Manage cross-zone-region replication for Azure NetApp Files (preview)

Azure NetApp Files supports volume cross-zone and cross-region replication on the same source volume.

Requirements

• Cross-zone-region replication supports creating two replication relationships for a source volume: cross-zone replication, cross-region replication, or a combination.
• Cross-zone-region replication volumes must abide by the same requirements and considerations as individual cross-zone replication and cross-region replication volumes.
• You must break the secondary relationship before you can perform a reverse resync operation with cross-zone-region replication. For more information, see Resync volumes after disaster recovery.
• Azure NetApp Files replication is supported within a subscription and between subscriptions under the same tenant.
• Fan-out deployments are supported for two destination volumes: one source (read/write) volume and two destination volumes.

Register for cross-zone-region replication

Cross-zone-region replication for Azure NetApp Files is currently in preview. You need to register the feature before using it for the first time. Feature registration may take up to 60 minutes to complete.

1. Register the feature

   Register-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANFOneToTwoReplication
   

2. Check the status of the feature registration:

   Note

   The RegistrationState may be in the Registering state for up to 60 minutes before changing to Registered. Wait until the status is Registered before continuing.

   Get-AzProviderFeature -ProviderNamespace Microsoft.NetApp -FeatureName ANFOneToTwoReplication
   

You can also use Azure CLI commands az feature register and az feature show to register the feature and display the registration status.

Configure replication

1. On the source volume:

   • If you're using an existing volume without an availability zone: populate it with an availability zone.
   • If you're creating a new volume: create it with an availability zone.

2. Under Properties, take note of the source volume’s resource ID. The source volume's resource ID is required to complete the next two steps.

3. Create the cross-zone replication destination volume.

4. Create the cross-region replication destination volume.

5. Authorize data replication from the source volume.

6. In the source volume’s menu, select Replication. Confirm there are two volumes listed under Destination volumes.
