1
00:00:00,320 --> 00:00:03,900
So we have this two gigabytes gp2 EBS volume available

2
00:00:03,900 --> 00:00:06,730
to us and we can take a snapshot from it.

3
00:00:06,730 --> 00:00:10,520
So if we do actions, we can create a snapshot.

4
00:00:10,520 --> 00:00:14,280
So we can add a description, for example, demo snapshots

5
00:00:14,280 --> 00:00:16,850
and then click on create snapshots.

6
00:00:16,850 --> 00:00:20,170
So then on the left hand side menu, instead of volume

7
00:00:20,170 --> 00:00:23,690
you can click on snapshots and snapshots should use a list

8
00:00:23,690 --> 00:00:25,200
of all the snapshots you have.

9
00:00:25,200 --> 00:00:27,310
And as you can see, we have one right here,

10
00:00:27,310 --> 00:00:29,955
it is completed, it is 100% available,

11
00:00:29,955 --> 00:00:32,870
and we get some information around that snapshot itself.

12
00:00:32,870 --> 00:00:34,590
First of all, what we can do is

13
00:00:34,590 --> 00:00:37,890
that we can copy this snapshot into another region.

14
00:00:37,890 --> 00:00:40,670
So if you right click and do copy snapshots

15
00:00:40,670 --> 00:00:42,610
then as you can see, you can copy the snapshot

16
00:00:42,610 --> 00:00:45,126
into any destination region that you want.

17
00:00:45,126 --> 00:00:48,550
And this can come in very handy in case you want

18
00:00:48,550 --> 00:00:51,010
for example, to have a disaster recovery strategy

19
00:00:51,010 --> 00:00:52,380
to make sure your data is backed

20
00:00:52,380 --> 00:00:55,123
up in another region of AWS.

21
00:00:55,123 --> 00:00:58,000
So I won't do so but you get the idea.

22
00:00:58,000 --> 00:01:00,380
Another thing I can do is take the snapshot

23
00:01:00,380 --> 00:01:03,400
and I can recreate a volume from it.

24
00:01:03,400 --> 00:01:07,000
So, action, create volume from snapshots

25
00:01:07,000 --> 00:01:10,450
and we choose a two gigabytes, gp2 volume

26
00:01:10,450 --> 00:01:13,570
and then the target AZ doesn't have to

27
00:01:13,570 --> 00:01:18,230
remain eu-west-1a, it can be, for example, eu-west-1b.

28
00:01:18,230 --> 00:01:19,592
And we can also encrypt this volume

29
00:01:19,592 --> 00:01:21,800
if we wanted to and add some tags.

30
00:01:21,800 --> 00:01:24,930
And so as we can see, when we click on create volume

31
00:01:24,930 --> 00:01:26,500
what's going to happen is that

32
00:01:26,500 --> 00:01:28,900
if we go back into our volumes,

33
00:01:28,900 --> 00:01:31,770
well now we have two volumes, as you can see.

34
00:01:31,770 --> 00:01:36,150
And one of them, this one, was restored through snapshots.

35
00:01:36,150 --> 00:01:39,200
Okay, and it is an eu-west-1b.

36
00:01:39,200 --> 00:01:40,720
So the idea is that thanks to snapshots

37
00:01:40,720 --> 00:01:42,460
we can quote end quote

38
00:01:42,460 --> 00:01:46,550
copy EBS volumes across different availability zones.

39
00:01:46,550 --> 00:01:47,942
And that's very handy.

40
00:01:47,942 --> 00:01:49,700
If we look again at snapshots

41
00:01:49,700 --> 00:01:53,310
we can have a look at what's called the recycle bin.

42
00:01:53,310 --> 00:01:54,730
So the recycle bin is a way

43
00:01:54,730 --> 00:01:57,120
for you to protect your EBS snapshots

44
00:01:57,120 --> 00:01:58,530
from accidental deletion,

45
00:01:58,530 --> 00:02:02,290
as well as your Amazon Machine Images.

46
00:02:02,290 --> 00:02:04,460
So we can create a retention rule

47
00:02:04,460 --> 00:02:07,763
and saying demo retention rule.

48
00:02:09,210 --> 00:02:10,330
And then we're saying

49
00:02:10,330 --> 00:02:12,930
we'll apply this to all EBS snapshots.

50
00:02:12,930 --> 00:02:15,890
And I want them to be retained for one day after deletion

51
00:02:15,890 --> 00:02:17,560
which allows me to recover them.

52
00:02:17,560 --> 00:02:20,260
So if I click on create retention rule

53
00:02:20,260 --> 00:02:21,800
now it has been created

54
00:02:21,800 --> 00:02:24,820
and it is going to appear right here at some point, okay.

55
00:02:24,820 --> 00:02:28,115
So let's refresh the page for us to see it, here it is.

56
00:02:28,115 --> 00:02:30,890
And now on the resources, we can see

57
00:02:30,890 --> 00:02:33,560
if we have resources in the recycle bin.

58
00:02:33,560 --> 00:02:37,890
So let's go back into our snapshots in the EC2 console.

59
00:02:37,890 --> 00:02:41,330
So I'm going to go into EC2, here we go snapshots.

60
00:02:41,330 --> 00:02:42,860
Little shortcut.

61
00:02:42,860 --> 00:02:45,750
And what I'm going to do is take the snapshots.

62
00:02:45,750 --> 00:02:47,020
And first, before I delete it

63
00:02:47,020 --> 00:02:48,270
I wanna show you the storage tier.

64
00:02:48,270 --> 00:02:51,390
So right now it is a standard storage tier, okay.

65
00:02:51,390 --> 00:02:55,200
But you can move the storage tier by archiving snapshots.

66
00:02:55,200 --> 00:02:57,240
And so like you to move the storage tier

67
00:02:57,240 --> 00:03:00,630
into another pricing level, but if you want to restore it

68
00:03:00,630 --> 00:03:03,540
of course you will have to wait 24 to 72 hours.

69
00:03:03,540 --> 00:03:05,010
So just to show you, but anyway

70
00:03:05,010 --> 00:03:06,620
let's go ahead and delete the snapshot.

71
00:03:06,620 --> 00:03:09,920
So we'll delete the snapshots, as you can see it's gone.

72
00:03:09,920 --> 00:03:12,980
And before it used to completely delete the snapshots

73
00:03:12,980 --> 00:03:14,620
and you couldn't recover it, okay.

74
00:03:14,620 --> 00:03:15,810
As you can see, it's gone.

75
00:03:15,810 --> 00:03:18,180
But now, thanks to the recycle bin,

76
00:03:18,180 --> 00:03:20,720
well, if I refresh here my resources

77
00:03:22,580 --> 00:03:25,210
I can now see that my snapshot has appeared here.

78
00:03:25,210 --> 00:03:28,380
And what I can do is click on it and recover it.

79
00:03:28,380 --> 00:03:31,370
Yes, recover resources and voila.

80
00:03:31,370 --> 00:03:34,830
It's back into my snapshots on my EC2 console.

81
00:03:34,830 --> 00:03:37,070
Okay, that was pretty awesome, right?

82
00:03:37,070 --> 00:03:38,740
Okay, that's it for EBS snapshots.

83
00:03:38,740 --> 00:03:39,810
I hope you liked it.

84
00:03:39,810 --> 00:03:41,860
And now will see you in the next lecture.
