A warm welcome to Veeam community editions

What are the Veeam community editions?

Veeam is introducing the Veeam Community Edition for Veeam Backup & Replication and Veeam One. It actually already has the community edition for Office 365. Up to now, Veeam offered a free edition of VBR but that was, while good and helpful, limited in use cases. The tech community at large used it for many “one-off” situations. In combination with the free edition of the Veeam Agents for Windows and Linux, you could already protect your physical hosts and the VMs running on them.

With the community edition, which offers offer more functionality and capabilities than the free edition, allows us to get started with Veeam at zero cost. This is a smart move, a small company can leverage the Veeam Suite now without any hassle and if they like it can easily move to a paid version that allows for more users and, if needed, more features and capabilities. Let’s give a warm welcome to the Veeam community editions!

Veeam backup for O365 community edition

This was the first community edition that Veeam made available in 2018. It offers full functionality with the following limitations:

  • Maximum # of Exchange Users: 10
  • Maximum # of OneDrive for business users: 10
  • The maximum amount of SharePoint data protected: 1 TB
  • Best effort support

Veeam backup community edition

The Veeam Backup Community Edition becomes available with VBR Update 4. I have played with it during RTM and it worked flawlessly in my 100% physical Windows Server 2019 lab and with a mix of Windows OS versions on the hosts. You do not need a license. You just install VBR 9.5 U4 without a license file and you have the community edition. Easy. The Veeam Backup Community Edition has the Standard functionality but it is limited to 10 Instances.

Veeam ONE community edition

The Veeam ONE Community Edition will be released later this year. It allows for only 1 Veeam B&R (paid or community edition) to be added and it has the following limitations:

  • Partial application level monitoring
  • Partial backup repository heatmaps
  • No email customization
  • Some reporting functionality is not available

An overview of what you get with the community edition

Look at the matrix below. You get a lot with the community editions, even integration with the Veeam Agents. A freelancer or small company it is an absolutely superb way to get started with rock-solid data protection and a recovery strategy. As a partner or consultant, it is super easy to drop these versions in an existing environment and let the customer get a taste of the licensed editions. If the Veeam community editions do all you need, well that’s it. Enjoy it courtesy of Ratmir Timashev & Andrei Baronov.

In a later blog post, we’ll take a look at Veeam Agent for Windows 3.0 as this version has some nice capabilities that really make it hit the sweet point.

802.1x Support with the Hyper-V switch is here!



Anyone who has had to support developers and IT Pros alike running Hyper-V on their clients and test systems in an environment with 802.1x port authentication knows the extra effort you had put into workarounds. This was needed due to the fact that the Hyper-V switch did not support 802.1X EAPoL. Sometimes it was an extra NIC on non-authenticated ports, physical security for rooms with non-authenticated ports, going Wi-Fi everywhere and for everything etc. But in conditions where multiple interfaces are a requirement, this becomes impractical (not enough outlets, multiple dongles etc. or add in cards).

On top of that, there was always at least someone less than happy with the workaround. 802.1x Support with the Hyper-V switch looks like it could or should work when looking at the vNICs both on the host and inside the VMs. You’ll see that the authentication properties are there, the policies to make it all work are pushed but no joy, authentication would fail

802.1x Support with the Hyper-V switch is here!

Windows Server 2019 LTSC (1809) & Windows 10 (1809), as well as the 1809 or later SAC versions, now offer 802.1x Support with the Hyper-V switch.

This is not enabled by default. You will need to add a registry key in order for it to be enabled. Form an elevated command prompt run

Reg add “HKEY_LOCAL_MACHINE\SYSTEM\CURRENTControlSet\Services\vmsmp\parameters” /v 8021xEnabled /t REG_DWORD /d 1 /f

This change requires a reboot. So, we also give the Hyper-V host a kick

shutdown /r /t 0

When you have a Hyper-V switch that you share with the management OS you will see that the management vNIC now authenticates.

You can also authenticate VMs. Depending on your needs the configuration and setup will differ. 802.1x allows for Single-Session/Single-Host, Single-Session/Multiple-Host, Multiple- Session (names, abilities vary with switch type, model, vendor) and you’ll need to work out what is needed where for the scenarios you want to support, you won’t have one size fits all with port authentication. I’ll be sharing my experiences in the future.

The point is you’ll have to wrap your head around port authentication with 802.1x and its various options, permutations on the switches and radius servers. I normally deal with Windows NPS for the radius needs and the majority of my sites have DELL campus switches. Depending on the needs of the users (developers, IT Pros, engineers) for your VMs you will have to configure port authentication a bit differently and you’d better either own that network or have willing and able network team to work with.


Hurrah! I am a very happy camper. I am so very happy that 802.1x Support with the Hyper-V switch is here. This was very much missing from Hyper-V for such a long time the joy of finally getting makes me forget how long I had to wait! For this feature, I will shout “BOOM”!

With the extra focus on making Hyper-V on Windows 10 the premier choice for developers, this had to be fixed and they did. There are a lot more environments in my neck of the woods that leverage (physical) port authentication via 802.1x than I actually see IPSec in the wild. It might be different in other places but, that’s my reality. With ever more mobile and flex work as well as body shoppers, temp labor that bring their own devices I see physical port authentication remain for a very long time still.

Windows Server 2019 is a supported guest OS on Windows Server 2016 Hosts

Is this even a concern?

While many of you are probably already running Windows Server 2019 VMs in test and production without a worry a little hiccup in the Microsoft documentation cause some concern. So, yes, it is, or rather, it was. Some people noticed or were told that Windows Server 2019 is not a supported guest OS on Windows Server 2016 Hosts. That was a mistake in the documentation and confused some people and account managers. But, yes. Windows Server 2019 is a supported guest OS on Windows Server 2016 Hosts. No worries!

The documentation mistake has been fixed

When we look at Supported Windows guest operating systems for Hyper-V on Windows Server and GitHub https://github.com/MicrosoftDocs/windowsserverdocs/commit/2c54e781c64e0cc3fec2cef349a762b972987870#diff-5347e6e782aa2be9a9ec94ff6ef0436b today we’ll see that the mistake has been corrected. In good tradition of Hyper-V the host support guest OS versions up to N+1. This means that Windows Server 2019 is a supported guest OS on Windows Server 2016 Hosts.

But until recently you might have seen the below.

This is what caused the concern. It was a simple mistake. So please if someone tells you Windows Server 2019 guests are or might not be supported on a Windows Server 2016 host, tell them to check again and point them to the above links.

Windows Server 2019 is a supported guest OS on Windows Server 2016 Hosts

The good news is that the mistake is fixed and all is well. I’m sorry if your decision makers or managers who got shown those documents before that mistake was fixed got scared but all is well. Windows Server 2019 is a supported guest OS on Windows Server 2016 Hosts. Be happy and start rolling out and upgrading as soon as you have all things like backup covered. I know I am.

Move Storage Spaces from Windows 8.1 to Windows 10


I recently assisted a little at a help desk. It was to validate the steps to move storage spaces from Windows 8.1 to Windows 10 workstations (DELL Precision). The engineers tend to have considerable local storage needs. Delivering to them both the capacity and performance they need, as well a choice in protection levels, was facilitated tremendously by Storage Spaces.

Ever bigger sized SSD and NVMe disks helped a lot as well. I remember way back when we built and validated a workstation configuration that had a JBOD to achieve the needed IOPS and capacity. That was very cool. Not literally (it produced quite some heat) and it was also a bit noisy. But their needs at that time required it. We have it easy now with 4TB NVMe, SSD readily available. Then again, the need ever more and faster storage. That has not changed at all.

PS: making backups is easier than ever as well and for that, I leverage Veeam Agent for Windows. You have free and paid versions and it is a great tool in our arsenal. You can have them leverage it as a DIY solution or centrally manage it from the Veeam Backup & Replication console. Whatever fits your need and budgets.

Why Storage Spaces in the first place

By leveraging storage spaces for the data volume(s) we avoid a dependency on raid controllers. The quality ones are expensive and you run the risk that when the workstation needs to be replaced you either have to move the raid controller with it (drivers, firmware and support might be an issue) or you can’t easily move between controllers when dealing with different vendors.

Move Storage Spaces from Windows 8.1 to Windows 10

Let’s take a look at the Storage Pool and the volume in the old Windows 8.1 workstation. As you can see all is well. I advise you to fix any issues before you move the disks to the new Windows 10 Workstation.

A healthy Storage pool
The volume with all the engineering data

Shut down the Windows 8.1 workstation.
Remove the disks used in the storage spaces pool from the Windows 8.1 workstation.
Add these disks to the new Windows 10 workstation (no raid controller or such, Storage Spaces rules apply!).

You can have up to 10 drives in most modern workstations. Buy your own drives for better pricing & sizing.

Boot the Windows 10 workstation and log in.
Open Windows Explorer. The data on the Storage Spaces volume is already there and accessible. Smooth!

All the data is right there !

Open Storage Spaces Manager. You will see an informational block about upgrading the Storage Spaces pool to enable new features. This is recommend when you know you don’t have to move the pool back to an older OS.

Informational block about upgrading the Storage Spaces pool to enable new features

Click change settings and click on Upgrade pool. You will be ask to click the button upgrade pool to confirm this. Note that when you upgrade the pool you can no longer move it back to Windows 8.1.

Upgrade the pool to enable the new features that come with Windows 10.

That’s it. As Upgrading the storage pool is fast and online. The only downtime was to physically move the disks from the old to the new workstation. As the last action, I choose to optimize drive usage when the workstations are returned to the engineer’s desk. This is new in Windows 10.

Just let it run. It has some performance impact but the engineers where too happy with a easy data move and their new workstation to complain about that.


Banking on storage spaces to provide some organizations their GIS and CAD engineers with a lot of local storage in their workstations has proven to be a rock solid choice. They get to have both capacity and performance which can be balanced. Large SSD disk sizes have been a great help with this. Anyway, one makes choices but ours to leverage storage spaces on the client has been a success. The migration of the disks from old workstations to new ones was easy and straightforward. It allowed us
to move storage spaces from Windows 8.1 to Windows 10 workstations easily. The portability of Storage Spaces rocks. IT Support happy, clients happy. Some of the engineers on their own or with the helpdesk are replacing disks for bigger ones or moving to SSD.
