1
00:00:01,080 --> 00:00:13,620
In this lecture I will explain how to take a snapshot of the VM so that if something wrong happened

2
00:00:13,680 --> 00:00:23,670
or we have mis configured the system we can revert back to this snapshot and continue from the point

3
00:00:23,730 --> 00:00:26,100
that everything was correct.

4
00:00:26,100 --> 00:00:34,830
So in order to do that while the machine is running I can take a snapshot here in virtual box so I will

5
00:00:35,550 --> 00:00:48,080
go to the virtual box window here and then I will click here on this icon for the camera.

6
00:00:48,470 --> 00:00:50,840
The snapshots so

7
00:00:53,600 --> 00:00:57,150
then I will click on take.

8
00:00:57,530 --> 00:01:00,740
Then I have to name the snapshot.

9
00:01:00,740 --> 00:01:04,070
So I will limit as security

10
00:01:06,500 --> 00:01:21,980
union snapshot one and I can add some more information like ready to use.

11
00:01:21,990 --> 00:01:26,460
And also here on the description I can enter more information like

12
00:01:29,170 --> 00:01:33,450
updated and then also

13
00:01:40,180 --> 00:01:43,900
TV shows installed

14
00:01:47,070 --> 00:01:50,760
also we set up

15
00:01:53,570 --> 00:01:57,570
and also I can add the date.

16
00:01:57,820 --> 00:02:11,000
So twenty six of June 2000 and 18

17
00:02:14,250 --> 00:02:17,630
and then I will think okay.

18
00:02:18,280 --> 00:02:29,960
So now we see that virtual box is taking the snapshot for the VM and we see here that our snapshot was

19
00:02:29,960 --> 00:02:32,470
taking successfully.

20
00:02:32,750 --> 00:02:44,150
Now in the next lecture I start to explain how to use security union tools and in particular I will

21
00:02:44,150 --> 00:02:56,240
start with explaining how to use that TCB replay comment in order to replay some backup packets in order

22
00:02:56,300 --> 00:02:59,990
to simulate traffic in our network.
