Hyper-V Replica is a new feature added to the Hyper-V Role in Windows Server. It uses an asynchronous data replication technology for organizations to implement an affordable Business Continuity and Disaster Recovery (BCDR) solution for virtualized workloads. This allows virtual machines running at a Primary Site to be efficiently replicated to Secondary Site (Replica Site) across a LAN/WAN link without relying on software or hardware technologies outside of the Windows Server 2012 Operating system. In Windows Server 2012 R2, Microsoft has enhanced Hyper-V Replica features like Extended Replication and configurable Hyper-V Replica frequency options.
