Lab Objective:
Learn how to create a snapshot of a virtual machine.
Lab Purpose:
Snapshots capture the state of a system at a certain point in time. They allow a system to be restored to where it was. They are useful if you want to test something. They can be done while the system is running or offline.
Lab Tool:
VirtualBox running Windows 10, but any OS will work fine.
Lab Topology:
Please use the following topology to complete this lab exercise:
Lab Walkthrough:
Task 1:
Open VirtualBox and click on your Windows 10 install. Then from the top right choose ‘Machine Tools / Snapshots’. Bear in mind that this button may move as they release new versions of VB.
Task 2:
Click on ‘Take [Snapshot]’ and give the snapshot a name.
Task 3:
Click ‘OK’ and you will see the snapshot captured.
Task 4:
Start the VM, open Notepad, and save a file onto the desktop. Then power off the machine.
Task 5:
Restore the snapshot. You can right-click it and press ‘Restore’ or click once and hit the ‘Restore’ button.
You can save a new snapshot if you wish.
Task 6:
Start the machine with Snapshot1.
Task 7:
When it boots, you will see the file isn’t there.
Note:
Most VM software has snapshot capability-built in.
