Recovery Time Objective (RTO), or the maximum tolerable business application downtime, is determined by factors in bringing up the application and providing access to the data at the second site. The storage portion of the RTO for breaking the peering relationship to activate the destination volume and provide read and write data access in the second site is expected to be complete within a minute.

## Cost model for cross-region replication

8387
With Azure NetApp Files cross-region replication, you pay only for the amount of data you replicate. There's 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. For more information, see the [Azure NetApp Files Pricing](https://azure.microsoft.com/pricing/details/netapp/) page.

2325
The Azure NetApp Files support for one Active Directory (AD) connection per NetApp account feature now allows each NetApp account to connect to its own AD Forest and Domain, providing the ability to manage more than one AD connections within a single region under a subscription. This enhancement enables distinct AD connections for each NetApp account, facilitating operational isolation and specialized hosting scenarios. AD connections can be configured multiple times for multiple NetApp accounts to make use of it. With the creation of SMB volumes in Azure NetApp Files now tied to AD connections in the NetApp account, the management of AD environments becomes more scalable, streamlined and efficient. This feature is in preview.
