A walkthrough and my views of use cases for the new Hyper-V 3.0 Replica feature.  I have been impressed with its stability so far and for the price it has great potential in providing a cold copy of your VMs in an alternate location across the room or across the world for organizations unable to afford larger enterprise solutions.  Where do you see Hyper-V Replica fitting in?  As always feel free to leave comments below.

The pre-beta version of Hyper-V 3.0 boasts a number of new and improved features, including a virtual machine replication technology known as Hyper-V Replica. It uses the Hyper-V Volume Shadow Copy Service (VSS) writer to prepare a snapshot of the virtual machine (VM) on the primary host (which can remain active) and moves the data to the secondary host. This capability adds disaster recovery capabilities to Hyper-V 3.0, allowing a virtualization administrator to have cold, ready copies of VMs anywhere in the world.

Hyper-V Replica creates copies on a VM-by-VM basis.While it is possible to replicate every VM to an alternate host with Hyper-V Replica,  in my experience, the tool is better suited to replicating one-off line-of-business VMs that provide important infrastructure fault tolerance, rather than full virtual environments. As such, Hyper-V Replica may be impractical for large enterprises with hundreds or thousands of VMs. In these situations, administrators can use PowerShell to configure multiple VMs at once.
