Microsoft Azure Backup Agent

Download the Azure Backup Agent

Microsoft works heavily on their Microsoft Azure Recovery Services and releases new features for its Azure Backup software. Some of these new features need a new version of the Azure Backup Agent, or MARS Agent, to work.

Now if you install a new recovery vault in Azure to get started with Azure Backup you will find a link to download the Azure Backup Agent or sometimes you will see warnings in the Azure Backup MMC console with a link to a newer version of the Azure Backup Agent. But if you just want to download the latest MARS Agent, sometimes it is pretty hard to find, so let me help you with this link:

Download Azure Backup Agent

You can also use that file to updated an existing Azure Backup Agent.

By the way, Microsoft Azure Backup now supports Windows System State Backups to Azure.



Windows Server 1709 Server Core Sconfig

How to install Windows Server 1709

Microsoft just released the new Windows Server version 1709 in the Semi-Annual Channel. This blog post is for beginners which want to do their first step setting up Windows Server Core.

First you boot your server or virtual machine form the Windows Server 1709 ISO file. and select which Operating System you want to install. You can choose between Windows Server Standard or Windows Server Datacenter. As you might see, there is only Server Core available. The Server with Desktop Experience or Full Server is only available in the LTSC (Long-Term Servicing Channel) in Windows Server 2016.

Windows Server 1709 Operating System

After accepting the license terms, you can choose the installation type. Even there is an upgrade option, you should choose Custom which will be a new install. Since an in-place upgrade from older Windows Server versions is not supported.

Windows Server 1709 Installation Type

Choose which drive you want to install and the partitioning you want to use

Windows Server 1709 Choose Disk

After that Windows Server will install itself, and reboot for a couple of times.

Windows Server 1709 Installation

After the installation is finished you have to set the default Administrator password.

Windows Server 1709 Admin Password

When you login for the first time, it runs the Windows command prompt with the common Windows commands, or you can run PowerShell, or if you need the magic key to the server core configuration you can run “sconfig” which allows you quickly to do configuration changes, install updates and more.

Docker Windows Server Container Images

Docker Container Images for Windows Server 1709 and new tagging

Last week Microsoft announced new Windows Server 1709 and the new Windows Server 1709 container images. The new container images in Windows Server version 1709 are highly optimized, especially in size. So for example the new Nano Server Container Image in 1709 is 5x smaller than the Nano Server Container Image in Windows Server 2016.

Microsoft also made some changes to tagging which is interesting.

If you want to use the latest images of the container images based on the Windows Server 2016 (which is in the Long-Term Servicing Channel, LTSC) you just run:

This will give you the latest images of the Windows Server and Nano server container images. If you want to run a specific patch level of the Windows Server 2016 (LTSC)m images, you can run the following:

Docker Windows Server Container Images Size

If you want to use the new Windows Server 1709 container images from the Semi-Annual Channel you can run the following

and again you cans also add a specific base OS container image by using a KB number:

If you already tried out the new container images during the development using the insider images, they still existing:

However, I am not sure what the plan for the insider images is going forward.



Docker for Windows Update Linux Containers

How to run Docker Linux Container on Windows 10 Fall Creator Update

I just blogged about how to run a Docker Linux Container natively on the new Windows Server version 1709. Docker today released a new update for Docker on Windows which also enables this scenario a little bit easier on your Windows 10 machine. It will ask you if you want to use the new feature to run Linux Containers natively on a Hyper-V Container running on Windows 10 (without the Moby VM).

As you can see the only thing right now you have to turn the feature on and off, since in this technical preview it is not yet possible to run Linux and Windows containers in parallel. But I guess soon that will be the case.

What you need is:

  • Windows 10 Fall Creators Update (Build 16299, Version 1709, RS3)
  • Docker for Windows 17.10.0-ce-win36 (13788) or higher

Enable Linux Containers on Windows

You can change the settings in the Docker Settings:

Docker for Windows Settings Enable Linux contianers on Windows

With hat setting on you can now run Linux Containers such as ubuntu on Windows directly, without having a Linux Virutal Machine running in the background to host the Linux containers.

Docker Run Ubuntu on Windows 10 Verions

Now you can also do some other fancy things like run the Azure CLI in a Linux Container on Windows 10.

Docker Azure CLI on Linux on Windows 10 Container

Simple and effective, and it will be even more powerful when you can run Linux and Windows Container in parallel on Windows Sever and on Windows 10.



How to run Docker Linux Container on Windows Server 1709

As mentioned Microsoft released the final version of Windows Server 1709 in the last week. Windows Server 1709 brings a couple of new improvements, especially in the container space. Microsoft and Docker are working on bringing Linux Container support to Windows Server, so you can now run Windows and Linux Container at the same time on a Windows Server Container Host running Windows Server 1709 or Windows 10 with the Fall Creators Update (1709).

In this post I want to show you how you setup up a Container Host to run Windows and Linux Containers at the same time using Docker.

Create Container Host Virtual Machine

Enable Nested Virtualization

If you run Docker on a physical server you can skip this step. If you want to run Docker Containers using Linux inside a Virtual Machine running on Hyper-V you should enable Nested Virtualization for the Container Host Virtual Machine. You can do this by running the following command:

if you want to do this on a Hyper-V Server in Azure, check out this post: How to setup Nested Virtualization in Microsoft Azure

Install Docker Enterprise Edition Preview on Windows Server 1709

First you have to install Docker Enterprise Edition Preview on your Windows Server 1709 container host. You can install the Docker EE preview using PowerShell package management, using the following commands:

As mentioned this is a preview version of Docker EE which enables a bunch of new features, to run Docker in production environments please use Docker EE 17.06.

Enable Docker Linux Containers on Windows

The preview Docker EE package includes a full LinuxKit system (13MB) for use when running Docker Linux containers. To enable this use the following command:

to disable it again use the following:

Run Linux Docker Container on Windows Server

Docker Ubuntu Container on Windows Server

Now you are able to run Linux Containers on Windows Server 1709.

for fun you can also run Nyancat!

Docker Nyan Cat on Windows Server

Things are still in preview, so don’t expect to work 100% 🙂

What is next for Windows Server and System Center with a faster release cadence

Windows Server, version 1709 is only the first step in this new world of faster release cadences. The most important aspect of having new releases twice a year is customer feedback will shape the product. You can try the preview builds of Windows Server in the Semi-Annual Channel and provide feedback by joining the Windows Insiders program. You can also join the conversation in the Microsoft Tech Community where we have tons of professionals and experts sharing their learnings and answering questions.



Windows Server Semi-annual Channel Overview

Windows Server release information – Windows Server Semi-Annual Channel and LTSC

As mentioned a couple of months ago, Microsoft has updated the Windows Server servicing model. The Semi-Annual Channel is a twice-per-year feature update release with 18-month servicing timelines for each release and the Long Term Servicing Channel (LTSC) will be support for 5+5 years as we know it form previous Windows Server releases as Windows Server 2012, Windows Server 2012 R2 and Windows Server 2016. This is similar servicing model as the Windows 10 client.

In short:

The Semi-Annual Channel provides opportunity for customers who are innovating quickly to take advantage of new operating system capabilities at a faster pace, both in applications – particularly those built on containers and microservices – and in the software-defined hybrid datacenter.

Customers also have the option to continue using the Long-Term Servicing Channel releases, which continue to be released every 2-3 years. Each Long-Term Servicing Channel release is supported for 5 years of mainstream support and 5 years of extended support.

You can find more information about the Windows Server Servicing changes in my blog post: What is next for Windows Server and System Center with a faster release cadence

Today Microsoft released a page where you can get an overview about the Windows Server versions and their support end dates.
