Scenario: A Citrix Architect is designing a multi-data center Citrix Virtual Apps and Desktops environment that will use Citrix Provisioning (PVS) to manage Virtual Delivery Agent (VDA) machine images. Each data center will have a separate PVS farm. During design discussions, the architect created a diagram to depict the way in which vDisk files will be replicated among PVS farms, based on the available storage for the vDisk stores.

Overall, the customer has identified 3 objectives for the image-replication process:
* Administrative time required to replicate images among farms must be minimized.
* The process must be usable by storage administrators without PVS farm administrative permissions.
* Pre-existing infrastructure and processes should be used where possible.
Which method should the architect use to replicate vDisk files among data centers?
