1
00:00:01,040 --> 00:00:04,220
Azure Backup Server. I have to warn you here that we're

2
00:00:04,220 --> 00:00:06,670
going to be seeing quite a few acronyms here. I was going to

3
00:00:06,670 --> 00:00:08,860
say TLAs, three‑letter acronyms,

4
00:00:08,860 --> 00:00:13,090
but it's actually FLAs, four‑letter acronyms. And yes,

5
00:00:13,090 --> 00:00:14,950
you do have to know this for the exam.

6
00:00:14,950 --> 00:00:17,240
I'm not the kind of teacher who does filler.

7
00:00:17,240 --> 00:00:21,180
So first there's the Microsoft Azure Recovery Services agent,

8
00:00:21,180 --> 00:00:23,350
affectionately called the MARS agent.

9
00:00:23,350 --> 00:00:26,130
Now this is simply an extension,

10
00:00:26,130 --> 00:00:29,310
a free bit of software you can install on your Windows

11
00:00:29,310 --> 00:00:33,070
Server systems that extends the built‑in Windows Server

12
00:00:33,070 --> 00:00:36,140
backup, or wbadmin, as it's called.

13
00:00:36,140 --> 00:00:40,240
This MARS agent is appropriate not for enterprises,

14
00:00:40,240 --> 00:00:44,020
but for one‑off scenarios, because we're not talking about

15
00:00:44,020 --> 00:00:47,460
orchestrating the backup of an entire multi‑tier workload.

16
00:00:47,460 --> 00:00:51,960
We're also not talking about orchestrating the backup of dozens,

17
00:00:51,960 --> 00:00:54,010
hundreds, thousands of servers.

18
00:00:54,010 --> 00:00:54,980
It's not scalable.

19
00:00:54,980 --> 00:00:58,970
It's a one‑off agent that simply unlocks a connection,

20
00:00:58,970 --> 00:01:01,950
an authenticated connection, between individual

21
00:01:01,950 --> 00:01:04,440
servers and a Recovery Services vault.

22
00:01:04,440 --> 00:01:07,170
The supported workloads are files and folders,

23
00:01:07,170 --> 00:01:10,740
volumes, and system state, pretty bare bones.

24
00:01:10,740 --> 00:01:14,800
If you're looking for bare‑metal restore, you cannot do that with

25
00:01:14,800 --> 00:01:17,890
the MARS agent and the Recovery Services vault.

26
00:01:17,890 --> 00:01:21,870
If you're looking to back up an Exchange server farm on premises,

27
00:01:21,870 --> 00:01:26,170
you can't do it. If you're looking to back up SQL Server clusters or more

28
00:01:26,170 --> 00:01:30,140
orchestrated workloads, you're going to need, not the MARS agent,

29
00:01:30,140 --> 00:01:34,640
but wait for it, the Azure Backup Server, or MABS. I kid

30
00:01:34,640 --> 00:01:36,880
you not, MABS is what it's called.

31
00:01:36,880 --> 00:01:42,820
MABS, or the Azure Backup Server, the M is Microsoft, is a free scaled‑down

32
00:01:42,820 --> 00:01:48,200
edition of an enterprise license product Microsoft has called Microsoft System

33
00:01:48,200 --> 00:01:51,840
Center Data Protection Manager, or DPM for short.

34
00:01:51,840 --> 00:01:56,400
In fact, you'll find that when you're using the free Azure Backup Server,

35
00:01:56,400 --> 00:01:59,460
you'll see references to DPM all over the place,

36
00:01:59,460 --> 00:02:05,400
because it is, in fact, the DPM engine, but it's been significantly scaled back.

37
00:02:05,400 --> 00:02:10,940
The idea is if you want full functionality, you'll need licensing for DPM.

38
00:02:10,940 --> 00:02:16,400
MABS is a way to give hybrid cloud backup and integration with

39
00:02:16,400 --> 00:02:19,360
Recovery Services vault to more customers.

40
00:02:19,360 --> 00:02:20,660
That's the idea.

41
00:02:20,660 --> 00:02:23,260
And so, therefore, there's more supported scenarios.

42
00:02:23,260 --> 00:02:25,670
There's "bare metal" backup and restore,

43
00:02:25,670 --> 00:02:30,940
SQL Server, Exchange Server, SharePoint Server, and also very importantly,

44
00:02:30,940 --> 00:02:39,000
backup for Hyper‑V VMs and VMware VMs. That's quite significant. Now let's do our next demo.
