On my Hyper-V R2 virtual platform, I’m often using differentiating disks to preserve disk space. Basically, I have this hierarchy of differentiating disk : OS 1.vhd Dev platform.vhd User 1 dev computer.vhd User 2 dev computer.vhd Production platform.vhd Server 1.vhd Server 2.vhd … this is great for saving space, at the creation time.
