Safety First, Safety Second - Snapshots are like Ctrl+Z

In the shortest video I have ever made for CodeReviewVideos, we will cover how to create a Snapshot of our Ubuntu Server, which will become a point in time copy of our Server exactly as it was (i.e. working) before we move on any further.

Even though this video is short, the importance of this step cannot be overstated. Unless you enjoy wasting hours rebuilding your test environment, take regular snapshots before toying with Ansible commands as it doesn't always go swimmingly the first time - especially when you are learning.

If it only takes 11 seconds to show, and can save you ~30 minutes rebuilding... why would you not? :)
