Saw this post in the Technet newsletter. Good stuff. I won’t be using it now (wish I were managing a Hyper-V environment in the first place! setting up replicas is a far away dream L:)) but thought I should point to it anyways. Maybe some day I’ll need to use Hyper-V replicas and I’ll search my blog and come across this … maybe maybe! :)
From my ESXi training I know VMware has something similar (vSphere Replication). The latter is a paid additional feature while Hyper-V replicas are free. Also, here’s a comparison by Aidan Finn.
