 # Cross-region replication of Azure NetApp Files volumes
 
-The Azure NetApp Files replication functionality provides data protection through cross-region volume replication. You can asynchronously replicate data from an Azure NetApp Files volume (source) in one region to another Azure NetApp Files volume (destination) in another region.  This capability enables you to failover your critical application in case of a region-wide outage or disaster.

 ## Cost model for cross-region replication  
 
-With Azure NetApp Files cross-region replication, you pay only for the amount of data you replicate. There is no setup charge or minimum usage fee. The replication price is based on the replication frequency and the region of the *destination* volume you choose during the initial replication configuration. See the [Azure NetApp Files Pricing](https://azure.microsoft.com/pricing/details/netapp/) page for more information.

 * Your *destination* volume is from the Azure NetApp Files *Standard* service level. It is in the *US East 2* region.
 * You’ve configured an *hourly* based cross-region replication between the two volumes above. Therefore, the price of replication is $0.12 per GiB.
