Windows 2016 and Storage Spaces as a Veeam backup repository
As Microsoft Windows 2016 is now finally generally available, people are starting to seriously looking at its features, and no doubt S2D together with the new ReFS 3.1 is one of the hot topics.

And I started to ask How can we leverage ReFS BlockCloning and Storage Spaces to make Windows 2016 the best solution for Veeam repositories? What about Storage Spaces Direct?”.
