## Properties
<a name="aws-properties-efs-filesystem-replicationdestination-properties"></a>

`AvailabilityZoneName`  <a name="cfn-efs-filesystem-replicationdestination-availabilityzonename"></a>
 For One Zone file systems, the replication configuration must specify the Availability Zone in which the destination file system is located.   
Use the format `us-east-1a` to specify the Availability Zone. For more information about One Zone file systems, see [EFS file system types](https://docs.aws.amazon.com/efs/latest/ug/storage-classes.html) in the *Amazon EFS User Guide*.  
One Zone file system type is not available in all Availability Zones in AWS Regions where Amazon EFS is available.
