About Veeam 9.5, secret killer feature and heresy

About Veeam 9.5, secret killer feature and heresy


Hello ladies. And dudes. DK here.

3 days left before the Ignite and 2 days before I board a plane. That’s quite a journey to get from Saint-Petersburg, Russia to Atlanta. 4 hours to Paris, then 10 hours to Atlanta. And 4.5 hours layover. Luckily I missed the latest two seasons of Game of Thrones, so I’ll be entertained enough.

Now about 2 cool features of upcoming Veeam Backup and Replication 9.5:

First: Integration with Veeam Agent for Linux!

It’s so cool, you just add a VBR server in the settings of Agent for Linux and it automatically appears in your VBR console.




And now the killer feature.

Are you ready?

You can change the GUI color! w0000000t

new colors of Veeam UI

Let me try that Marine Blue

Veeam UI color blue

But wait…that’s just 4 colors, including 1 standard. What if I like other ones? Let me imagine that in Photoshop…using my madskillz

Sorry about that.

Anyway, you’ll be able to see the new colors and Agent for Linux integration at Ignite yourselves. See you there

And both features in one video🙂

DK out.

About My, Microsoft’s and Veeam’s big plans

About My, Microsoft’s and Veeam’s big plans

Hello, human readers and search engine bots. DK here.

I recently moved from to a hosted version, so now I can use plugins! Ugh, I didn’t actually realise, how limited the .org version is.

But anyway, the use of plugins will let me create a quiz page, and I’m gonna create my own VMCE v9 practice test. There’re quite a few tests out there, but when you are preparing, the more, the better. Especially when it comes to the ones that cost you money. You can trust me on this, I’m preparing for VCP6-DCV myself right now.

But that’s just a heads-up for you, I honestly have no idea how much time I’m gonna spend on it, but it would be a good thing to do. Let’s hope I finish it before the New Year.

That’s me. Yep.

Veeam’s plans

As for Veeam, TODAY, Sept 22 at 1pm ET we’re having a VeeamLive with MVPs Clint Wyckoff and Dave Kawula. And it’s not yet another boring webinar. Clint and Dave are always making their conversations with a good portion of laugh deep technical overview and demos (Dave + Clint are better together… humm, sorry, Veeam’s messaging is running in my veins🙂)

The topic, AFAIK is about Veeam B&R 9.5, ReFS and Windows Server 2016 and if you need a bit more information about this technology in advance, you can check out my previous post.

Now let’s get to Microsoft’s plans.

Microsoft’s plans

Finally, after such a long wait, Windows Server 2016 is coming with its own change block tracking mechanism among other enhancements. They call it Resilient Change Tracking. Let me try and explain it to you from scratch:

Hyper-V didn’t have any native CBT up until today, so backup vendors had to create a filter driver that would monitor changed blocks. This isn’t the best solution because adding a third-party filter driver can cause issues to the hypervisor and even BSODs. Some vendors had better drivers than others, but Microsoft implemented CBT to solve potential issues. The new Windows Server 2016 is coming with a built-in system of Resilient Change Tracking(RCT).

Change block tracking today, in Hyper-V, as we know it, has one major issue. All those blocks that are being tracked are kept in a memory bitmap on the host.

If anything happens to the memory (such as a VM migration or power outage), the whole bitmap is lost, you don’t know what changed anymore, and you’ll have to spend time and resources on doing a full rescan. RCT solves this problem: It creates three bitmaps: one in memory and two on disk.

The one in memory works the same way as you know it today (if you don’t, read my full blog post here). Nothing changes here, and it is the most granular of the three bitmaps. As long as the VM is running, the backup solution will look at that bitmap and copy the changed blocks only when an incremental backup is being requested.

The difference is when the VM is being migrated, or there is a sudden power outage. Now the backup solution has two bitmaps to choose from:

The .mrt file and the .rct file, as you can see in the below image:

The RCT file will be used in normal operation. For example, when the VM is moved to another host and you lose the memory bitmap, this one will be used. The RCT file is more granular than the MCT file (but less than the memory bitmap). It uses normal writes.

However, when there is a sudden power loss or similar event, the MRT file (Modified Region Table) can be used. It is written in write-through mode and uses a coarser tracking granularity. Therefore, in a case of a sudden power loss, the MRT file still has a good record of what has changed on the disk.

Even though the two on disk are less granular, it’s still much better than doing a full backup or rescan after a power outage. Also, those files are always attached to an associated VHD(x) and travel with it if a machine is moved.

All in all, Resilient Change Tracking is a long-awaited feature of Hyper-V 2016. It is designed to make incremental backups easier and faster, plus backup vendors don’t have to create and support their file system filters anymore.

That’s all folks

About Veeam, Count Dracula and Bitlooker

About Veeam, Count Dracula and Bitlooker

Happy Wednesday, my fellow readers, and casual internet viewers. DK here.

Not everyone knows that, despite the fact that Veeam’s HQ is located in Switzerland, the actual location of two main offices is in Saint-Petersburg, Russia. I’m working in one of them, and it is right here (you can even press “view larger map” and check out the street view):

The second one is relatively close; others are scattered around the world, and I’ll probably get to them eventually🙂.

Occasionally we get people from our other offices. This week, for example, we have our colleagues from Romania (see: Count Dracula, Romanian Longhorn). In fact, Romania is going to become our big location in the nearest future, getting the same big office with the same functions.

You don’t see that, but most of our marketing campaigns, webinars and whitepapers are managed from our SPB office. This is, in fact, the office of marketing, sales, and financial departments. And we have the designers here. And the backend systems. Well, we have a bit of everything, roughly 400 people in this very building.

But back to what you’ve come here for. Today’s small note is about Bitlooker. If you’ve read “Bitlocker”, please read it again. Okay, okay, relax, even Google reads it wrong.

First of all: did you know that the files you’ve deleted actually stay on disk? In fact, what happens is a file system removes only a path to these files, so they become sort of hidden, but still can be extracted with special software (if you ever tried to recover your files/photos/whatever, you know what I mean).

Bitlooker reads through the virtual disk and understands if the files were deleted. Then it just excludes disk blocks containing these files from a backup thus reducing its size. As far as I know it works not only in our Veeam B&R, but also in Agent for Windows and Agent for Linux.

Also, it excludes swap and hibernation files, but that’s not that interesting. And, did I mention, you get for FREE*!

I’ll let you find the appropriate checkbox yourself:

As you see Veeam loves you and saves you precious disk space and even more precious bandwidth.

Stay tuned for more.

About Veeam, demo labs and ReFS

About Veeam, demo labs and ReFS

Hi again, testers of new technologies in your lab (’cause your boss doesn’t want to jump on the bandwagon🙂).  DK here.

I’ve been recently watching some VCP Foundation videos and researching some Microsoft technologies and my question to you is: how the heck can one be an MVP and vExpert at the same time without getting his head exploded?

This week I’m planning on finishing the Veeam’s demo lab and fly to Atlanta for MS Ignite. My part in this lab preparation is mostly setting up Agent For Linux and integration with VBR (yeah, I still remember I have to write something about it). Those of you who have been at VMworld US and have seen Veeam’s lab there, know that I had my hand in that lab!=)
