Scenario: A Citrix Architect needs to design a multi-datacenter XenApp and XenDesktop environment that will use Provisioning Services (PVS) to manage Virtual Delivery Agent (VDA) machine images. Each datacenter will have a separate Provisioning Services farm. During the design discussions, the architect creates a diagram to depict the way vDisk files will be replicated between PVS farms, based on the available storage for the vDisk Stores.

Overall, the customer has identified the following objectives for the image replication process:
Minimize the administrative time required to replicate images between farms

Must be usable by storage administrators without PVS farm administrative permissions

Utilize pre-existing infrastructure and processes where possible

Which method should the architect use to replicate the vDisk files between datacenters?
