all right. Our next task is to take a snapshot
virtual machine, and then we'll see how those work.
So what I'm gonna do is go to my Window seven council
and there's actually a snapshot button dedicated button where you could go to the VM menu and select snapshot from here.
So go ahead and take a snapshot,
and we'll call this one
We're just gonna snap shot the virtual memory.
Another option is to cool. Yes, the guest file system.
What that means is, um
virtual machines are being sent
two other hosts or other data stores.
Basically, a snapshot of this type is used
and quit gassing the file system slows everything down
the virtual machine,
just file and the contents of the memory
shift over the network to the other host.
We're gonna leave that unchecked for our purposes.
Okay, so we click. Okay,
and we'll see our progress along the bond here will take out a little bit for the
to create the snapshot.
We'll come back in just a moment.
Okay? So snapshot just completed.
personalized. My desktop.
I'm going to pick the United States theme
that we'll have a different background image.
Picture a lighthouse there. So let's take another snapshot
and we'll call this after
and that's not shot will take a little while to complete a CZ. Well,
meantime, I can go to my V MNU snapshot
and then open up the snap shop manager.
So I was doing a different test earlier. I have an older snapshot
that I created before I deleted some files
so you can start to see the usefulness of the snapshot. Here
you can delete files. You can make changes to your system.
you do some snapshots before
applying a patch or some kind of upgrade.
Okay? And it's not such a ship,
just about done. And there it is.
I've got my original desktop background,
and after the background change,
any extra description information would be here.
So in order for us to see this in action,
what I can do is go back to my original desktop background.
Saul, Select that snapshot and click Go to
gives you a little chance to back out. I'll say Yes,
you know there was. When I reverse this snapshot was actually pretty quick.
It only took a few seconds, and I can see that I'm clearly back
to the configuration of my machine before I made the change to the background.
It has a little bit of extra work at the end to copy any changes to the disk
that have transpired since the last configuration change.
Then once that's completed,
I condone Revert back to
the background change.
Okay, so that's finished,
and you'll notice that it changed the structure of
Of where that you are here is a little bit
snapshot I'm actually using, which is my original desktop. I'll go back to mine after background change so we can go back the other direction.
and this will take just a few seconds and we go back to
snapshot that we that we took originally.
So it's very easy to switch back and forth if you're doing some kind of testing and you don't want to
go through complicated steps to undo something,
is the way to go. You do need VM are tools installed
in order to use this, however, so be aware of that.
Okay, so now I don't want to use my snapshots and more. Um, actually want to delete some of these so I can select a single won't click delete,
take a moment because it does have to delete a fair amount of data
and the other option that we have
if you're if you're done with all your snapshots is too
Okay, So now I'd like to delete all my snapshots,
so I'll just select any one of them and just say, delete all clicked lead. All
tells me it removes all of them. Don't want to continue. Yes, I do.
And this is when you're when you're done with all of your snapshot activity. You want to do this?
If you keep snapshots around
longer than you need to, they continue to grow
eventually. If if this has left alone long enough and a lot of changes were happening to that system, then you will use up your all your available storage.
So this is a typical thing that
can but you And when you're in a production environment, you need to periodically
look for the machines in your environment that have snapshots and then go find out if they're needed. If they're not needed, then you want to get rid of him.
All right, that concludes. Lab number 12
We'll actually be working with the V app, Virtual app.
So we'll create one powered on and then, uh, shut it down and get rid of it.
All right. Thank you. So you on lap 13?
