Managing VM replication

VM replication is a disaster recovery feature within Hyper-V. Hyper-V creates a VM replica on a remote Hyper-V server and keeps that replica up to date as the original VM changes. The VM on the remote host is not active during the normal operation of the original VM. You can make the replica active should the VM's host fail for some reason.

With Hyper-V replication, the source VM host bundles up the changes in a running VM's VHD file(s) and regularly sends them to the replica server. The replica server then applies those changes to the dormant replica.

Once you have a VM replica established, you can test the replica to ensure that it can start should you need it. Also, you can failover to the replica, bringing the replicated VM up based on the most recently replicated data. If the source VM host becomes inoperable before it can replicate changes on the source VM, there is a risk of the replication process losing those changes.
