I've added Windows support to Snap, now making it possible to take snapshots of a Windows machine using the same simple tooling as with Linux. Thus it is now possible to move both Windows and Linux instances across disparate VM hypervisors and cloud providers. You may download the windows installer here
Snap not only permits moving an instance between any two generic hypervisors and/or cloud providers, but between any physical or virtual machines as well as well as taking and restoring generic system snapshots.
Stay tuned for more updates!
