This Virtualbox tutorial will show you how to take a snapshot on Virtualbox. First you will see how to take a snapshot of a running virtual machine. You will then see how to restore the snapshot. Snapshots allow you to save the state of a virtual machine; this can be useful when you want to test something, or you’re about to make a change to that virtual machine, and you need to be able to roll back to a working instance. Snapshots have saved me on numerous occasions and are an excellent feature!
