Virtualization has so many benefits, not just in corporate environments, but even in your home environment. One of them is ability to create “snapshot”. Snapshot is exact copy of your operating system memory status and content, regardless of whether the machine is powered on or in shutdown state. This means, that you can revert, or to be precise restore, your virtual machine as it was when you created snapshot, any time you want.
I just said, regardless of whether the machine is powered on or in shutdown state. I will show both scenarios. First if your virtual machine is in shutdown state, select virtual machine and on the top right side of window select icon Snapshot (Slide 1).
On next screen select same icon in order to create snapshot (Slide 2.).
Add meaningful name of file and description. My recommendation is to put date or even time in to file name. Make description with as much as you can information`s of packages and applications installed (Slide 3). Select OK in order to create snapshot.
You can verify that everything is done on next window, as I did in slide 4. Snap will be shown below options to restore or clone.
Now, if your appliance is in running state, select Machine and then select Take snapshot (Slide 4).
Name your file and give it description, as you already did before (Slide 5). Select OK.
Now you can monitor process of saving your virtual machine snapshot (Slide 6).
With this feature you can restore your appliance or even clone it if you need more copies of same virtual machine. On this way you can create minimum baseline standard for any operating system functioning in your environment.
