00:00:03

and let's start with the cloud is

00:00:06

evil, he makes sure that the stuff that belongs to

00:00:08

you is flat, not the

00:00:10

creation of america supports your admin

00:00:13

supported ops yes and today it's supposed to be

00:00:17

about data backup the question is

00:00:22

zfs a backup Yes, so

00:00:26

some form of snapshots can be used as a backup

00:00:29

and we always have

00:00:31

a lot of headwind and the discussions are

00:00:33

usually quite short in our opinion.

00:00:36

Yes and what it looks like in detail, I'll

00:00:39

probably take the time to talk to you about it today.

00:00:41

I've been putting it off for quite a long time

00:00:43

But today I would really like

00:00:44

to talk to you about whether the ZDF saw the

00:00:47

snapshot thing here in backup

00:00:50

should or has to make a backup and how

00:00:53

it works and the whole thing is as

00:00:55

simple as possible. Today we are using

00:00:57

prox box again as a basis but

00:01:00

in the Principle is the same with in parts it

00:01:03

also works with Frieda in front of the with your Mac

00:01:05

but that has the highest

00:01:08

compatibility with Box Max Walther

00:01:10

most of it is in it and let's

00:01:12

just take a look at it now I

00:01:14

just have the definition of

00:01:18

somewhere for me made for a backup

00:01:20

then let's take another look at wikipedia

00:01:21

so for me first weapon backup is

00:01:24

important power is I would

00:01:26

like to have at least three copies in

00:01:28

at least two different places i.e.

00:01:30

if we 1 breaks that there is no

00:01:32

time phase in which you sweating and

00:01:35

worrying about what a second copy will

00:01:36

break, which is very likely

00:01:38

that you'll be left without anything.

00:01:40

Yes, that's important, so

00:01:43

three copies in two locations. Usually that's

00:01:47

two servers on site

00:01:50

that are mirrored productive

00:01:52

when things are going really well, they are

00:01:55

only spatially separated if that works and

00:01:57

if that doesn't work then they come

00:01:58

to us again so you can

00:02:00

rent it from us or in another part of the

00:02:02

building that is protected somewhere in terms of fire protection

00:02:04

or generally against major impacts

00:02:07

Then

00:02:10

move it out again, yes, that means that it's

00:02:13

gone if there's a fire, if something comes,

00:02:14

if it's broken into, whatever,

00:02:16

that nothing can get away, well then,

00:02:18

of course, it should happen as quickly as possible, so

00:02:21

that we bang bands

00:02:23

have it backed up very promptly So a live

00:02:25

history of the beautiful we are then

00:02:26

actually a replication that

00:02:28

is also another term that you have to

00:02:30

talk to again and of course there used to be knowledge and

00:02:33

semantics and hoarding and everything went

00:02:35

veritas who told me hey we have the

00:02:38

backup software no one said that we

00:02:43

are here at the start with the production of software yes small little detail

00:02:46

so that's what we just want to talk about

00:02:48

and now you just take a

00:02:50

quick look at the definition of a backup

00:02:53

according to wikipedia there are a

00:02:57

lot of different approaches and

00:03:01

Thoughts point about the backup that you

00:03:03

can get through all of them again on your own,

00:03:05

on the whole how do you do backup

00:03:07

let the legal situation

00:03:08

that can of course vary depending on

00:03:10

where you are and when you watch the video

00:03:13

and if there are any types of guys, yes

00:03:16

we have that Once the blurring,

00:03:19

I would also differentiate here again

00:03:20

between data documents

00:03:23

Excel shows PDF which is relatively

00:03:25

simple or complete virtual

00:03:27

machines are running in operation Yes, so

00:03:31

once the complete backup would be in the

00:03:33

classic case, switch off the computer, switch off the

00:03:35

virtual machine and

00:03:37

copy everything over and go

00:03:39

away We have to copy it, it

00:03:42

just doesn't take that much memory image

00:03:45

backup is mentioned here that would be the

00:03:48

snapshot story I freeze a

00:03:51

certain state a system can

00:03:53

change further

00:03:54

I can save the frozen state completely away

00:03:56

we had a nice side effect it's important

00:03:58

if you have a lot of them has files and

00:04:00

copies them for a very long time

00:04:01

then it may just be that he has to

00:04:02

start at the beginning to back them up which takes three days

00:04:04

the last files are new than like

00:04:06

files at the beginning

00:04:07

and if the files

00:04:09

belong together in some way yes then it occurred to me to

00:04:11

start with plastic because it It

00:04:13

's not consistent, that's why it would be

00:04:14

frozen first,

00:04:15

we can do a

00:04:17

differential backup,

00:04:19

it's a very quick story because it

00:04:20

defines which

00:04:22

blocks were backed up and afterwards

00:04:24

when you back up the changed blocks,

00:04:26

that's very nice

00:04:28

so you can be very burden-free and

00:04:30

systems slapshot differential backup

00:04:33

and the differences

00:04:35

ultimately get bigger and bigger over time and

00:04:39

at some point you have the problem that

00:04:41

the differences are almost as

00:04:44

big as the original and it is not

00:04:46

very efficient but in terms of size

00:04:48

but at least a lot Let's quickly

00:04:51

look at the whole thing and

00:04:53

then we have the

00:04:57

incremental backup on offer and there's something like that.

00:05:00

Incremental means I'll have

00:05:02

insurance at some point and

00:05:04

then the difference or just think

00:05:06

the change between the

00:05:08

insurance and the change That

00:05:11

the differential would be the second

00:05:13

time but no longer to

00:05:15

insure the change but to the

00:05:16

last incremental backup that is

00:05:18

relatively long,

00:05:19

that is very quite intensive and if

00:05:22

something is damaged in the chain then

00:05:24

point like the whole backup is no longer

00:05:26

that's what backup software promises us

00:05:28

to be able to

00:05:29

if the medium is broken then it's

00:05:32

harmoniously difficult zfs is a

00:05:35

journalist and can do that and has so

00:05:38

many checksums and power losses in

00:05:40

place that you

00:05:42

can actually rely on nothing happening

00:05:44

because the company is

00:05:46

already the company all snapshots so if I

00:05:48

have a bottle of everything, there is

00:05:49

no history that

00:05:51

has led to it, so if something

00:05:53

works in operation on ZFS then

00:05:56

the backup is also

00:05:59

OK so far. Now it's also

00:06:01

about determining what has

00:06:03

actually changed and if

00:06:06

you If you look at this in Wikipedia

00:06:09

then recognize the files that have changed,

00:06:11

that's of course relative, yes, it's

00:06:15

clear that I somehow

00:06:17

have millions of files then it doesn't take

00:06:18

time to finally see which

00:06:21

city has changed and can

00:06:23

determine the date if I have a

00:06:25

virtual machine I have a

00:06:26

completely different problem. I have to know

00:06:27

which blocks have changed

00:06:29

and there is, for example,

00:06:31

this continued tracking from vmware which is created out of sheer

00:06:34

desperation in the file where the

00:06:35

blocks are written in that in the end there is

00:06:37

no other way. So there

00:06:39

is Then the desperation of the

00:06:41

manufacturers is quite great. We do it

00:06:43

much more elegantly with ZF and

00:06:45

we have already explained this several times.

00:06:47

With Microsoft Backup, for example,

00:06:49

it works relatively well.

00:06:52

You can assume that with a

00:06:53

normal backup system it will take several

00:06:56

minutes It takes several hours for a

00:06:57

backup to start in some form and

00:07:00

with ZFS it starts every hour.

00:07:03

Ultimately, yes, what else can you

00:07:06

say about the backup here? It's still about

00:07:08

the strategy of how you set it up.

00:07:11

Ultimately, when do you make a backup and

00:07:15

fix it the all the bells and whistles

00:07:17

that are not relevant to us at all

00:07:21

we usually have zfs snapshots

00:07:24

various very close in the last

00:07:27

time 8 448 4

00:07:30

hourly and then somehow 14

00:07:32

daily four weekly eight

00:07:34

weekly several months and the

00:07:36

results of the principal chain our

00:07:38

operation and if it works,

00:07:40

the chain is also OK, the

00:07:41

packing we did again was different, we are

00:07:43

highly efficient, we have shown it often enough

00:07:45

and from that side

00:07:48

we don't need a strategy because we have

00:07:49

everything there and of course nobody is stopping us

00:07:52

from doing it with the classic ones

00:07:53

On-board means of making some form of backup is

00:07:55

still possible.

00:07:57

Ultimately,

00:08:00

what we normally

00:08:02

do as administrators is we buy

00:08:06

some form of data backup software, which can

00:08:08

be quite lengthy and expensive until

00:08:10

you even have the license and

00:08:12

have registered and it's

00:08:14

smooth sailing If you have installed it, it's tedious,

00:08:17

then you have to do a disk

00:08:18

management, which disks

00:08:21

if changed, where are they located? That's

00:08:23

time-consuming, that's no fun,

00:08:25

but the way it's normally done

00:08:27

on our channel here looks at it

00:08:29

or it's used

00:08:33

It's also saved, but it's important to note that programs like

00:08:35

backup exec and beam and co, whatever they're

00:08:37

called, have great functions that make up

00:08:39

almost 5,500 employees and ten admins,

00:08:41

but at the moment I have all the

00:08:43

switches in an emergency or a file

00:08:45

or to help my customer I do

00:08:49

n't want it to be proportionate, it does

00:08:51

n't make sense

00:08:53

to sell to customers the facility that takes three days to back up

00:08:54

the data, even if I can do it in

00:08:57

two minutes by car and just about a bulkhead

00:08:59

and be the backup or with

00:09:01

Frieda FCO II yes and even a

00:09:04

publication car dealership, which is

00:09:06

now also a katherine aspect,

00:09:08

will come up another time, yes,

00:09:10

that makes real sense,

00:09:12

that's why I went here and

00:09:15

thought about what are the

00:09:18

typical areas of application for zdf

00:09:20

and how do you deal with the accident so easily

00:09:24

and beautifully I mean we told me at the

00:09:26

beginning it's a backup, yes the

00:09:30

simplest thing is I'm playing back a file

00:09:31

from one to another from freenet

00:09:34

or from the release somewhere

00:09:36

and we've already

00:09:39

explained it a few times here in the channel but

00:09:41

we'll do it Again, it was

00:09:42

n't enough considering how easy it is and

00:09:44

how few commands there are. That's how it

00:09:46

works. In this case, I've now

00:09:53

created a data fed here to test it. You can

00:09:56

see that right now and then we'll air it out

00:10:00

let's do that here and then

00:10:02

you can see all the stars here

00:10:04

that end up with a mount that's why we

00:10:07

had folders

00:10:08

well so data compare

00:10:11

reports in the folder reinstetten ii

00:10:13

white then goes in there suggests a

00:10:18

file to me here is a damn important

00:10:19

file then I say z the snapshot

00:10:22

recovers without the flash because it's

00:10:24

not in the folder snapshot name to the starter field

00:10:27

then the trojan comes change

00:10:31

the file suspicious file I'm a

00:10:34

stupid trojan and then in the end

00:10:36

I say look is that there yes there is the

00:10:38

stupid trojan then I say to Rolf Beck

00:10:42

the snapshot look at the important file

00:10:44

again yes that is that is weatherproof

00:10:48

netshop with files year exciting

00:10:50

seasoning in defect with you simply have

00:10:53

the opportunity to

00:10:57

take a snapshot here and get it back

00:10:59

if you are still busy with work and so

00:11:01

that Now you can also do it with vdk

00:11:04

fund nff, it's a lot

00:11:08

easier if you just

00:11:09

take out a file quickly and then let's see

00:11:13

what it looks like,

00:11:16

we'll see there's nothing there, then

00:11:20

let's go in the subfolder dot zfs

00:11:23

snapshot and then the name of the network

00:11:26

in this case was snap and

00:11:31

then we look and then we see that this

00:11:33

damn important file already

00:11:35

existed and then you can simply

00:11:40

copy this damn important file to where you want and that's

00:11:42

just great, you can either copy them

00:11:44

back into the productive system

00:11:45

with cp or with scp onto

00:11:48

another box and that's of course

00:11:49

great because here too if you

00:11:54

have a small one in front of you or a search stick in

00:11:56

the You can also do this via but you

00:11:58

have 1000 files on the internet

00:12:00

looking for over 10,000 files ultimately

00:12:02

the files of the older version

00:12:04

are accessible at any time and you can do that

00:12:06

via this snap the this point

00:12:08

zff this point zff snapshot folder

00:12:12

it's actually that easy you You have

00:12:14

a virtual machine running somewhere

00:12:17

that can now be under Windows or

00:12:19

Linux with the file system NTFS FT

00:12:22

or Extra

00:12:24

and you've made a lot of trouble with snapshots and

00:12:27

now you really need a

00:12:31

file back. Yes, I mean, what can you

00:12:34

do with something like that, of course

00:12:35

Virtual disk can

00:12:36

roll back the network known to Scots if

00:12:39

something goes wrong but there is still

00:12:40

the case that you

00:12:42

say okay, I still have

00:12:43

a Windows data backup running in the evening

00:12:44

but it's 2 p.m. and the

00:12:46

file from 1 p.m. that would be it That's what

00:12:48

I want and this use case

00:12:51

we're just going to do now boy

00:12:53

and that should now be valid for

00:12:56

Prox Yes, some of it can also

00:12:58

be compatible with Freezers.

00:13:02

But this workflow function actually works best with Boxee Box

00:13:03

or media because that's where The file system

00:13:07

NTFS and ext3 or ext4

00:13:11

are already known if you do it on the Mac

00:13:12

then it still works with Windows

00:13:15

but no longer works with Linux

00:13:16

and you have the extension installed so that

00:13:18

's why it's simply a matter of

00:13:19

situations we have a virtual machine in operation

00:13:23

Now I need a file from the beginning of the hour

00:13:25

that comments

00:13:27

on the tomb of Jan Hirsch and our

00:13:30

most complicated case.

00:13:31

The machine is in operation and I need

00:13:34

a file out, which means I have to get the

00:13:35

virtual platter in the form of a vdk

00:13:39

or pipe, it will be very heavy or kuka was

00:13:42

the one petitions table are in there again

00:13:44

and the moment when I'm doing

00:13:45

cleaning work, which is the standard with

00:13:47

ZFS, so where you create a virtual disk,

00:13:50

it makes a reservation that is

00:13:52

suitable as a device, appears as a device and

00:13:55

you then take it

00:13:56

and you can do that now So

00:13:58

normally you would have to shut it down

00:14:00

because when I open something it

00:14:02

never changes, it does

00:14:04

n't work all the time,

00:14:06

so I'm going to make a clown of it, it stays

00:14:08

in this clown with the files taken

00:14:10

out via mount, that's the plan and

00:14:13

quite a few arrows I will

00:14:14

provide all of this, the screenshots

00:14:16

again, maybe even the blog post

00:14:17

and now look at how easy

00:14:20

it is to get the files out of the smart hock.

00:14:23

In the end you would simply have to

00:14:25

copy them out.

00:14:26

The other alternative would then be the

00:14:29

files or the disk that was worth

00:14:31

it Putting the Windows machine

00:14:32

in will also show that, so let's go

00:14:35

and have a look at the whole thing.

00:14:37

I'm very happy with that.

00:14:42

The idea is as follows. I'll let you

00:14:46

list all of them now and

00:14:48

I'm interested in it was Schmidt's lift

00:14:51

and at Prock with QSC like the vn whistles,

00:14:54

this Windows machine

00:14:56

has the number 100 and here I can see

00:14:59

that the number 100 only

00:15:02

has a single disk that is

00:15:05

occupied by gigabytes and in the total

00:15:08

of all the snapshots it has 106 90 a

00:15:13

few weeks of storage time occupied

00:15:15

four times

00:15:16

that really has a lot going on ultimately

00:15:18

in it so david garrett a people of

00:15:20

other time so then let's go

00:15:22

see

00:15:23

I go to zfs creation so shows

00:15:27

me that real data on that was created

00:15:30

only the 100 disc or 100 0 1 we always

00:15:34

from the date format my choice of

00:15:38

car with schott does it like that and then

00:15:40

we actually spit it out here from the

00:15:42

now that was now a few days back

00:15:44

on today would have

00:15:47

had serious results he said apple data

00:15:50

service from 101 and there is a

00:15:54

snapshot to her from 1710 be careful budget or

00:15:59

railway program that can

00:16:01

be UTC and therefore the system time over 910

00:16:05

that is now the only

00:16:07

choice I have from that day so I assume that

00:16:09

can be there on the same day from

00:16:11

two hours ago or for the sake of clarity

00:16:12

Bastia simple what has to do is used to

00:16:22

cloning the whole thing into the same data center disc 9, that is, it will be small, it

00:16:25

will appear and the 9

00:16:28

they have had disks since the middle of the machine

00:16:29

is then the clown and

00:16:32

now you can call it up again

00:16:35

since In the commemorative publication you look for the

00:16:37

disc 100 and in the end you can see that

00:16:39

there is the 101 here that the

00:16:41

productive one has 106 and has

00:16:44

all the trimmings

00:16:45

and there are the ones here that have the

00:16:50

kilometer disc 9

00:16:51

and it only has 8 k in the end like that

00:16:54

and when I then shudder and effectively

00:16:58

and next to the fact where it is and let's

00:17:02

find out the 100 again with crepes here

00:17:03

then I see both of them

00:17:06

with all the partitions namely here the

00:17:08

productive one that that one here and the

00:17:11

cloned one and then Here are the numbers that come

00:17:13

out of the zentis and those that the world

00:17:16

needs right away.

00:17:17

In the end, I'm joking that the

00:17:19

disc is very current or if it's

00:17:22

short-term, so from the date Bush

00:17:25

wanted but it doesn't change

00:17:26

anymore, you can also read

00:17:28

write read only be instead of being funny and

00:17:32

now it's working in the end it says

00:17:35

everything is clear I'll make a folder

00:17:36

in the ETF there I'll only do that the

00:17:38

first time it stays yes I'll get

00:17:41

this list again as I said you can see

00:17:43

I ultimately mean petitions

00:17:46

there are three of them I assume in this

00:17:48

case it's the second partition here,

00:17:50

that's so typical Windorf and then I say

00:17:53

everything is clear to me and now

00:17:55

pay close attention here

00:17:56

fz full there it is back if I do

00:17:58

n't know so far tool data for 200

00:18:01

new part 2 or stop Alternatively, you

00:18:05

can take 20th century FZG 32 2 and

00:18:09

restore the dog completely unspectacularly,

00:18:11

it takes a second and the ball

00:18:13

dies

00:18:14

and then my files are here

00:18:15

and I can play them back to you. Yes, that

00:18:19

's if you understand that, it's

00:18:22

not that much If you do it two or three

00:18:23

times, you can't make a backup or

00:18:26

can it load any software,

00:18:27

install it, update it and play it back while it's

00:18:29

on here and then you can

00:18:32

copy it out with FDP and

00:18:34

provide it to someone or copy it away with FCP,

00:18:36

whatever, so that's

00:18:38

absolutely fantastic

00:18:40

yes then we have to

00:18:43

clean up the mess again at some point,

00:18:46

maybe in the worst case it won't be

00:18:47

at the same time and you say

00:18:50

everything is clear here that Catholics so

00:18:52

when is this one from or where does

00:18:54

this new disc come from then he says you

00:18:57

get this new one

00:18:58

just click on the bite clone can

00:19:01

be deleted

00:19:02

and then you can say all right the

00:19:04

mount me that again mnt restaurants and

00:19:07

snacks and then that's what you dream to me with

00:19:09

-11 old snapshots just give this

00:19:13

date this command is not a

00:19:16

hot thing afterwards gone and stays

00:19:19

That made it super easy for me, in the

00:19:21

end you make a copy of the

00:19:24

virtual platter, which is mapped as a virtual

00:19:27

platinum system and the

00:19:30

walls of the TD are simply

00:19:32

copied somewhere, then stuff on it gives me the

00:19:35

law and and is good for systems that ca

00:19:38

n't do that or if you're not that fit

00:19:40

then it's no problem to

00:19:42

make a clown and discreetly attach this clown

00:19:45

to the virtual machine

00:19:47

and let's just take a look at it now, it

00:19:49

's almost the same workflow

00:19:52

so in the end it's always the same way

00:19:55

you manage and in this case that is

00:19:57

the 100 lists you the snapshot,

00:19:59

we have already urgently

00:20:00

done that and tells zfs clown the number

00:20:05

of the snapshot it also offers this

00:20:08

obligatory disc 9 then you know

00:20:10

that it is the virtual disk and then

00:20:12

you can unfortunately A function

00:20:14

that is integrated with proximity is an

00:20:17

existing disk in which the main thing is to

00:20:18

take the virtual machine

00:20:24

number then that could also

00:20:26

be ideas 9 or SATA 9

00:20:29

but that has hot swap capability then the

00:20:33

name of the data store and then the name of

00:20:35

the record, they cloned the world

00:20:38

from 109 and all that nonsense

00:20:41

at the front here, it comes from the data store

00:20:43

definition but it's the same data

00:20:45

store as jo then he says here

00:20:49

with update confirmed you're allowed to do something

00:20:52

The consequence is that in Windows, a

00:20:53

new hard drive can

00:20:56

simply be displayed offline in newer Windows versions,

00:20:58

but you can already see

00:21:01

the partition fits, then you make it

00:21:04

online and then you have

00:21:06

already tracked the second hard drive here and

00:21:09

can go over it The

00:21:11

letter then copy the files out.

00:21:13

You do this preferably

00:21:15

if it is not the same system where you

00:21:18

originally did it. If you

00:21:20

wanted to boot then you would say, for example, but

00:21:23

then you would say that's what's coming. I'll get to that in a moment.

00:21:24

I can switch offline again In

00:21:27

any case, after that,

00:21:30

it ultimately disappears from the

00:21:31

virtual machine and this is

00:21:32

confirmed again with an update and is then

00:21:35

really plug-and-play instances if

00:21:38

the virtual was, for example, externally prox

00:21:41

disappeared from the host and machine

00:21:43

and the snapshot Velberter with the not

00:21:47

in the space needs the house away with

00:21:50

destroy the r and then again this

00:21:53

disentis in the end it

00:22:02

also works to boot so I could also do

00:22:04

these clown disputes and show it again like this

00:22:07

and here

00:22:09

again how it works relatively easy - so then here the

00:22:14

virtual machines around 100 then - -

00:22:18

boot of the chio nine would then be used to boot

00:22:22

the clone, 0 would then be used to clown the

00:22:26

same machine like this and if you

00:22:29

ultimately know that you are going to have two

00:22:31

at the same time please remember to have

00:22:33

a copy of the configuration create a

00:22:36

3par ddress with a different mac address or

00:22:37

network and nothing where you can

00:22:39

boot the same disk and then it works

00:22:41

and now the critics are saying that you

00:22:43

can't do that, yes, that

00:22:44

you're just not allowed to do that, that

00:22:46

's not a thing Backup something, what are

00:22:48

you doing? You're a disgrace for it.

00:22:51

That's broken because the holy backup

00:22:54

is steam or the original software from

00:22:57

the manufacturer. Please do it

00:22:59

downhill with the software from the

00:23:00

original manufacturer if you have time. Yes,

00:23:02

you can't do that yes so from

00:23:05

database damp it can take hours

00:23:07

or or a day or two days that it

00:23:09

takes forever you can do that we will

00:23:12

do that then

00:23:13

the database changes then things are missing are

00:23:15

broken the people have been there

00:23:18

for decades we already have the

00:23:21

mtfs like hps, zf swx and so on

00:23:26

it can also crash sometimes you saw

00:23:29

stromer fall there is weather the

00:23:31

file system is broken nor the database

00:23:33

but if you want the holy backup in the name of

00:23:35

the father and the holy spirit

00:23:37

I never

00:23:39

want to discuss it again with you, if you

00:23:41

have a system where there are two minutes a

00:23:44

day of downtime at any

00:23:47

time, which only then comes now the

00:23:49

sacred script name of the father of the

00:23:51

holy spirit, we will never

00:23:53

discuss it again, even with the

00:23:55

comments, then make a note of it here and if

00:23:58

you have two minutes a day where the

00:23:59

system can be down and

00:24:02

everyone who is doing the right thing

00:24:04

should then, apart from the fact that they

00:24:07

can anyway, as I said, you

00:24:09

can take your backup software, you can

00:24:11

take it from the content database and you

00:24:13

can take Windows backup and

00:24:14

that's what happens, but

00:24:17

he didn't think of it and that's the

00:24:19

holy [ __ ] in the end

00:24:21

and that's how the good script

00:24:25

space finally works so let's see here

00:24:27

and now you can get angry with your star device

00:24:32

out there Although we really have very little,

00:24:34

very little, I think that you didn't think of it,

00:24:38

so here it goes,

00:24:41

coachman and 103 tvm round one here, a

00:24:45

snapshot professional was here, you would

00:24:47

do everything, even on the lap driven

00:24:49

machine then you start it everything

00:24:52

again and while it starts on

00:24:53

its own it comes that replication script

00:24:56

almost all the stuff again on

00:24:59

another poison different is so difficult

00:25:03

that's just that's all that's all

00:25:05

attached people in front of him down briefly that

00:25:08

takes half a minute then he takes

00:25:10

the snapshot of it only takes seconds then

00:25:12

turns us on that only takes seconds

00:25:13

then he pushes it to the other

00:25:14

ship above it in house outside of

00:25:17

clean shutdown the file can

00:25:20

copy shrek which is completely in order in the tiger

00:25:22

it took a minute the

00:25:25

copy time is ridiculous than him

00:25:27

seen and agreed the backup in the house

00:25:29

takes 34 minutes

00:25:30

a daily backup outside the house takes

00:25:32

almost 12 hours

00:25:34

and then there is the clean shutter

00:25:36

and that's it, yes we like to do that

00:25:38

to the Connelly then that

00:25:40

's really really super easy

00:25:43

and At the end of the day, just

00:25:47

for fun, the replication shows how it

00:25:51

would work in this case, that would be

00:25:54

up here ZFS cent from the snapshot because

00:25:58

I took it before, as I have

00:26:00

already seen with the sophisticated ones, here next to it there is an

00:26:03

SSH connection and the target box in the

00:26:07

house at home and here zfs receive

00:26:11

with with the data fitness

00:26:17

was created sent all the stuff

00:26:18

around and at some point it is on the

00:26:20

target page and these scripts that we

00:26:23

have already described so many times zfs auto

00:26:26

snapshot with zfs backup or peace the

00:26:28

same thing Just make sure that you

00:26:30

can send endlessly incrementally you

00:26:33

have to have me with these 2x different

00:26:35

data carriers cast

00:26:38

productive systems the local replica the

00:26:41

external replica on all of them you have nothing

00:26:45

version with clean gravel and without

00:26:47

clean shutdown

00:26:48

I have, as I said, so many times

00:26:50

sharepoint exchange and sql and exchange

00:26:54

stuff have to be rolled back spain problem

00:26:56

but that doesn't stop you from continuing to

00:27:01

do a normal backup in addition

00:27:02

but and that's just the convenient

00:27:04

option if you asked about a defect

00:27:07

or christ is zfs and backup

00:27:09

year time that's it a baker zfs is

00:27:12

a backup and we also have a large

00:27:14

part of it, we don't use the built-in

00:27:16

tools anymore because they are so

00:27:17

reliable and before you

00:27:21

have a normal backup, I

00:27:23

prefer 50 snapshots a day, yes if

00:27:25

one of us is definitely good, yes if

00:27:28

it is network from which many already in iwate

00:27:30

yesterday what the half hour

00:27:31

that is whining at a very high level

00:27:33

and I have with levels backup and

00:27:35

backup is what you

00:27:38

push somewhere which is made transportable for efficiency

00:27:41

then you have to play it

00:27:42

back so

00:27:43

you You first have to have the sprint space

00:27:45

and the time and

00:27:46

play something like that back, that's not possible with ZFS

00:27:48

because every snapshot

00:27:50

you have

00:27:51

is immediately usable in the standby mode

00:27:59

you want to boot all the system look

00:28:01

it is there you

00:28:03

also want a replica a current version

00:28:05

that is there will be out of house current

00:28:07

version is there you want out of house

00:28:09

an old version cs also there yes integer

00:28:12

not integer that you can

00:28:13

do that yourself yes and that's what we

00:28:16

do and that's the be-all and end-all: next

00:28:20

pandemic and home work history, whatever

00:28:23

else may come if we

00:28:25

do it ourselves then we have to put ourselves in the

00:28:27

situation where they say okay, we'll

00:28:28

do it in house and if so that someone

00:28:31

is more portable then we might do it

00:28:33

outside of the house then

00:28:35

we'll let it run in our rz or

00:28:38

wherever that offers it for free just

00:28:41

think about it beforehand and then play it through on the side of things,

00:28:43

yes zfs

00:28:46

is a backup super olé olé

00:28:47

The second screen linked again

00:28:51

and the comment is open again for questions from the city.

00:28:55

In general, if you have any ZFS

00:28:58

questions you can send me the

00:29:00

Nazi attack on steak. I would

00:29:01

also like to answer a few questions

00:29:02

about it and have added Migros to the entry-level entry

00:29:07

The first

00:29:10

backup will now

00:29:14

perhaps summarize again quite nicely what

00:29:16

the possibilities are because we have

00:29:18

called them very kartmann the practice parts,

00:29:20

so we have just briefly

00:29:22

summarized what the

00:29:23

possibilities were in the end, so

00:29:26

we have them for once Choice between

00:29:28

data center is supposed to be one there is a

00:29:31

folder raw material can write in

00:29:32

files and other virtual disk that

00:29:34

brings with it a certain story

00:29:36

starting with the DAX I can do something

00:29:39

so snap schotten that is a

00:29:41

backup at the moment when I can do something all

00:29:43

print image something play back or

00:29:45

roll back year are backup I can

00:29:47

roll back as well as a

00:29:49

backup without recovery time even

00:29:51

I can clone that means I can do

00:29:53

more I have several backups the whole

00:29:55

cash register

00:29:56

change is ultimately no longer necessary in the

00:30:00

clown Kant has just tried to

00:30:03

do things or just just in this

00:30:05

tightness I can also boot a clown

00:30:09

that is typical for vdk sroka files

00:30:12

and I can also have the cloned little

00:30:15

modified restart with zfs

00:30:17

promote take over

00:30:19

I can use the snapshot folder point to

00:30:21

look at old files with the terminal

00:30:24

and sftp copied out read only I

00:30:27

can use Windows Explorer to

00:30:32

image previous file versions in peace with ZFS, which means

00:30:34

that the user can restore their own things

00:30:35

themselves, including a

00:30:37

backup and I can replicate it somewhere else

00:30:40

and I can

00:30:44

of course also freeze backups and widgets

00:30:46

not be destroyed by automation

00:30:49

and I can encrypt it on both sides as

00:30:51

I want, that works on

00:30:53

both sides with itself and

00:30:55

versatile only with free well then

00:30:59

she gives the z wolf ultimately dz wanted

00:31:02

virtual disks you can find them under the

00:31:03

deck yes the cards yes I can

00:31:07

roll them back if what's the

00:31:09

clown's pulpit on the clown can

00:31:11
