Windows Server 2012 R2 – Shared VHDX, DPM and Hyper-V Replica

So today is the first day (proper) of TechEd 2013 and so far it has been amazing. The conference centre is vast, the halls are huge and so far so good.

I went to the Introduction to Windows Server 2012 R2 session presented by Jeff Woolsey – that man is a fountain of knowledge!

So after they demo’d some of the new functionality around 2012 R2 I got thinking about how Hyper-V replica handles shared VHDX files – basically guest clustering without mapping raw LUNS through Fibre Channel or iSCSI? I also had a thought about how hyper-v backups via the host would work with this? And one more… Can you replicate a storage space?

Fortunately I managed to put these queries to Jeff.

It’s official – Hyper-V guests with a shared VHDX file cannot be replicated (you can replica the OSs but not the shared VDHX). Understandable due to the clustering aspects but disappointing.

Also backing up the guest OSs and data is not possible with hyper-v host level backups. Jeff’s answer here was to use back tools inside the guest vms. Not ideal – again understandable but still disappointing.

Replicating a storage space is not possible.

Who know’s – it might come in Server 2012 R3 or whatever the next iteration will be called, but it’s not coming in the R2.
