1
00:00:01,830 --> 00:00:11,320
Networks allow us to preserve this data off of virtual machine at any point in time and let us know

2
00:00:11,370 --> 00:00:19,880
Gundlach if need to be rolling back and indeed that may have been made since the snapchat was taken.

3
00:00:20,940 --> 00:00:29,460
This makes it easy to undo Jinny's or to test different conditions without having to manually undo what

4
00:00:29,460 --> 00:00:35,040
indications are installed in the system in order to get back to a known state

5
00:00:37,810 --> 00:00:44,620
he didn't cheat and we can work with snapshots on the many other window when the guest is selected by

6
00:00:44,620 --> 00:00:47,250
clicking over the snapshot area.

7
00:00:47,770 --> 00:00:53,590
Here we can take a snapshot with that grand state by passing along the Kembla button.

8
00:00:59,490 --> 00:01:06,830
When we do that we can give the snapshot a name and write a description of it if we want to as well.

9
00:01:07,320 --> 00:01:12,780
That's going to help us to remember detail about the state of the machines.

10
00:01:13,030 --> 00:01:15,680
Man this neighborhood was taken.

11
00:01:15,870 --> 00:01:19,870
I've been called this one myself short and press OK.

12
00:01:20,130 --> 00:01:27,480
We're going Dictionnaire Schwarzman a guest is running or when it's shipped off to Goldberg in through

13
00:01:28,470 --> 00:01:34,230
we need to shut down the guest and choose a point from which to the store.

14
00:01:34,330 --> 00:01:37,820
Not that we have a snapshot of this guest.

15
00:01:37,980 --> 00:01:39,160
Let's make a team.

16
00:01:39,180 --> 00:01:46,240
I will change the background image of my guest because that's easy and it's visible difference.

17
00:01:50,820 --> 00:01:51,410
All right.

18
00:01:51,420 --> 00:01:52,640
That's Tiede.

19
00:01:52,820 --> 00:01:55,440
I make a snapchat of this machine as well.

20
00:01:55,530 --> 00:01:59,800
But this time I'm going to use the machine and take a snapshot option.

21
00:02:00,300 --> 00:02:01,480
I really click.

22
00:02:01,490 --> 00:02:08,520
I been call this one blue blue background and I even click OK I've been checked on the guest and then

23
00:02:08,610 --> 00:02:17,070
I will go in and choose to restore the previous state with the gamelike on with the blue at all I have

24
00:02:17,070 --> 00:02:24,510
already made a snapshot of the team at stake so I don't need to create a snapshot of a current machine

25
00:02:24,510 --> 00:02:25,430
state.

26
00:02:27,540 --> 00:02:34,380
Had a not created a snapshot with a blue background all of those changes would be lost.

27
00:02:34,380 --> 00:02:35,990
I will choose these two.

28
00:02:36,030 --> 00:02:38,980
And then I will start my virtual machine.

29
00:02:39,330 --> 00:02:47,040
And this how the guest was before the teaching of the background was made I can switch back and forth

30
00:02:47,310 --> 00:02:53,320
keeping in mind that changes made in an oddly oddly snapshot.

31
00:02:53,330 --> 00:02:58,030
I want to paint the state of little snapshots.

32
00:02:58,070 --> 00:03:02,790
Snapshotting basically Falk's your virtual machine.

33
00:03:03,260 --> 00:03:13,540
You want to keep an eye on how many snapshots you are making and how complicated data not is snapshots.

34
00:03:13,550 --> 00:03:21,530
Don't take up as much space as the Holy Ghost but they do take up a little space so it's a good idea

35
00:03:21,620 --> 00:03:22,010
to

36
00:03:25,000 --> 00:03:32,100
unneeded snapshot occasionally delete unneeded snapshot and occasionally and keep in mind snapshots

37
00:03:32,100 --> 00:03:33,500
are not backup.

38
00:03:33,510 --> 00:03:40,740
We can also make duplicate copy or clone of the virtual machine of the state of the machine at a given

39
00:03:40,740 --> 00:03:41,680
snapshot.

40
00:03:43,920 --> 00:03:49,250
A clone is a different virtual machine rather than a copy of moment in a time.

41
00:03:49,310 --> 00:03:54,590
Once the clone is made you have effectively two identical ghast.

42
00:03:54,590 --> 00:03:56,470
There are two kinds of clones.

43
00:03:56,530 --> 00:04:04,690
A full blown and a link Glaum are full of them and makes a copy of this for the lonely little machine

44
00:04:05,150 --> 00:04:14,320
and a link clone uses the same basic file for both ghast Bustos anything is in the separate fine tuning

45
00:04:14,330 --> 00:04:17,730
in one against want to affect the other one.

46
00:04:17,930 --> 00:04:24,020
And they they each have their own set of data sources.

47
00:04:24,020 --> 00:04:25,360
Cloning is a good approach.

48
00:04:25,370 --> 00:04:33,340
If you have one what's your machine you want to use as a starting point for a handful of different machines

49
00:04:33,950 --> 00:04:34,920
to make a clone.

50
00:04:34,940 --> 00:04:43,150
I can either select guest on a snapshot and right click to find that clone option or look for the little

51
00:04:43,150 --> 00:04:45,370
cheap button and get it.

52
00:04:45,370 --> 00:04:55,000
I guess I can set a name and if the clone machine is going to be on the same network as regional it's

53
00:04:55,010 --> 00:04:59,610
a very good idea to make sure that MAC address is different.

54
00:05:00,020 --> 00:05:07,220
We can do that with this option here or change it manually in the setting later on on the next screen.

55
00:05:07,220 --> 00:05:11,470
I can choose whether to make a full on a linked clone.

56
00:05:11,660 --> 00:05:18,710
In this case I will use a full clone then I can choose whether I want snapshots to be cloned with the

57
00:05:18,710 --> 00:05:20,060
new machine.

58
00:05:20,390 --> 00:05:26,100
I can keep start it up alongside the other one if I want to.

59
00:05:26,330 --> 00:05:32,740
There's my clone and I can see that it's running right here next to reason.

60
00:05:33,350 --> 00:05:37,010
But for now I've known this on and saved some space.

61
00:05:37,010 --> 00:05:38,000
I really don't need this.

62
00:05:38,000 --> 00:05:44,910
Might I come to the remove and to delete all files.
