Azure Backup Server
This article illustrates on how to use Azure Backup Server v2 to backup on-premises and Azure Workloads. Though Azure Backup Server shares much of the same functionality as DPM. Azure Backup Server does not back up to tape, nor does it integrate with System Center. Azure Backup Server is a dedicated role. Do not run any other application or role with the Azure Backup Server.
You can deploy Azure Backup Server from the Azure marketplace or on a On-premises server. The requirement to deploy Azure Backup server on a on-prem infrastructure is to have the below OS.
|Windows Server 2016 and latest SPs||64 bit||Standard, Datacenter|
|Windows Server 2012/R2 and latest SPs||64 bit||Standard, Datacenter,|
Microsoft recommends you start with a gallery image of Windows Server 2012 R2 Datacenter or Windows Server 2016 Datacenter to create a Azure Backup Server. Here are the steps, you need to go through to deploy Azure Backup server.
Step1: Install Windows Virtual Machine from the Marketplace
- Sign in to the Azure portal at https://portal.azure.com.
- Choose Create a resource in the upper left-hand corner of the Azure portal.
- In the search box above the list of Azure Marketplace resources, search for and select Windows Server 2016 Datacenter, then choose Create.
- Provide a VM name, such as myVM, leave the disk type as SSD, then provide a username, such as azureuser. The password must be at least 12 characters long and meet the defined complexity requirements.
- Choose to Create newresource group, then provide a name, such as myResourceGroup. Choose your Location, then select OK.
- Select a size for the VM. You can filter by Compute typeor Disk type, for example. A suggested VM size is D2s_v3. Click Select after you have chosen a size.
- On the Settingspage, in Network > Network Security Group > Select public inbound ports, select HTTPand RDP (3389) from the drop-down. Leave the rest of the defaults and select OK.
- On the summary page, select Createto start the VM deployment.
- The VM is pinned to the Azure portal dashboard. Once the deployment has completed, the VM summary automatically opens.
Step2: Create Recovery Vault
- Sign in to your subscription in the Azure portal.
- In the left-hand menu, select All Services.
- In the All services dialog, type Recovery Services. As you begin typing, your input filters the list of resources. Once you see it, select Recovery Services vaults.

- From the list of Recovery Services vaults, select a vault.
- The Settingsblade opens up by default. If it is closed, click on Settings to open the settings blade.
- Click Backupto open the Getting Started wizard. In the Getting Started with backup blade that opens, Backup Goals will be auto-selected.
- In the Backup Goalblade, from the Where is your workload running menu, select On-premises.
- From the What do you want to backup?drop-down menu, select the workloads you want to protect using Azure Backup Server, and then click OK.
- In the Prepare infrastructureblade that opens, click the Download links for Install Azure Backup Server and Download vault credentials. You use the vault credentials during registration of Azure Backup Server to the recovery services vault. The links take you to the Download Center where the software package can be downloaded.
- Select all the files and click Next. Download all the files coming in from the Microsoft Azure Backup download page, and place all the files in the same folder.
Step5: Extract Software Package
After you’ve downloaded all the files, click MicrosoftAzureBackupInstaller.exe. This will start the Microsoft Azure Backup Setup Wizard to extract the setup files to a location specified by you. Continue through the wizard and click on the Extract button to begin the extraction process.
Step 6: Install Software Package
- Click Microsoft Azure Backupto launch the setup wizard.
- On the Welcome screen click the Next This takes you to the Prerequisite Checkssection. On this screen, click Check to determine if the hardware and software prerequisites for Azure Backup Server have been met. If all prerequisites are met successfully, you will see a message indicating that the machine meets the requirements. Click on the Next button.
- Microsoft Azure Backup Server requires SQL Server Standard. Further,the Azure Backup Server installation package comes bundled with the appropriate SQL Server binaries needed if you do not wish to use your own SQL. When starting with a new Azure Backup Server installation, you should pick the option Install new Instance of SQL Server with this Setupand click the Check and Install Once the prerequisites are successfully installed, click Next.
- Provide a location for the installation of Microsoft Azure Backup server files and click Next.
- Provide a strong password for restricted local user accounts and click Next.
- Select whether you want to use Microsoft Updateto check for updates and click Next.
- Review the Summary of Settingsand click Install.
- The installation happens in phases. In the first phase the Microsoft Azure Recovery Services Agent is installed on the server. The wizard also checks for Internet connectivity. If Internet connectivity is available you can proceed with installation, if not, you need to provide proxy details to connect to the Internet.
- Once registration of the Microsoft Azure Backup server successfully completes, the overall setup wizard proceeds to the installation and configuration of SQL Server and the Azure Backup Server components. Once the SQL Server component installation completes, the Azure Backup Server components are installed.
- When the installation step has completed, the product’s desktop icons will have been created as well. Just double-click the icon to launch the product.
Step7: Add a Data Disk to Azure Backup Server
- Log on to Azure Portal. In the menu on the left, click Virtual Machines.
- Select the virtual machine from the list.
- On the virtual machine page, click Disks.
- On the Diskspage, click + Add data disk.
- In the drop-down for the new disk, select Create disk.
- In the Create managed diskpage, type in a name for the disk and adjust the other settings as necessary. When you are done, click Create.
- In the Diskspage, click Save to save the new disk configuration for the VM.
- After Azure creates the disk and attaches it to the virtual machine, the new disk is listed in the virtual machine’s disk settings under Data disks.
Step8: Initialise the Disk of the Azure Backup Server
- Connect to the VM.
- Click the start menu inside the VM and type mscand hit Enter. Disk Management snap-in opens.
- Disk Management recognizes that you have a new, un-initialized disk and the Initialize Diskwindow pops up.
- Make sure the new disk is selected and click OKto initialize it.
Step9: Create a Storage Pool for Azure Backup Server
- Navigating to the Storage Pools page in Server Manager
- Launch Server Manager and navigate to the “File and Storage Services” page.
- Navigate to the Storage Pools page. Refresh the UI by clicking on the Refresh button.
- Logon as a user with admin privileges to your server, launch Server Manager, and then navigate to the “Storage Pools” page within the File and Storage Services Role.
- Right-click the “Available Disks” pool for the Storage Spaces subsystem and launch the New Storage Pool Wizard.
- Launch the New Storage Pool Wizard from the TASKS list.
- In the New Storage Pool Wizard, enter desired pool name and optional description. Make sure that you have selected the Primordial pool for the Storage Spaces subsystem.
- Select the number of disks needed for pool creation. If you want to designate a physical disk as a hot spare, then select the “Hot Spare” allocation type.
- Confirm the selected settings and initiate pool creation by selecting “Create” on the “Confirm selections” page.
Step10: Create a Virtual Disk
- Right-click the concrete pool that you just created (the pool where type value is Storage Pool), and then launch the New Virtual Disk Wizard.
- In the New Virtual Disk Wizard, make sure that you have selected the appropriate pool. Enter the desired virtual disk name and optional description.
- Select the desired storage layout and provisioning scheme as per your storage requirements.
- On the “Specify the size of the virtual disk” page, enter the desired size for the new virtual disk or pick the “Maximum size” option.
- If you pick the “Maximum size” option, the system will try to create the largest size possible for the virtual disk.
- If you select the check box for “Create the largest virtual disk possible, up to the specified size” while specifying the size then the system will try to create the largest size possible for the virtual disk up to the requested size.
- It is also important to note that the value showing up as the storage pool free space (in our example 43.8GB) shows the actual free allocation the pool has overall. For cases with a fixed provisioning of a non-simple storage layout such as Mirror or Parity, when defining the size of the virtual disk, you have to take into account the overhead of storage needed to create the extra copies of the virtual disks extents for resiliency. As a basic example, with the 43.8GB free space in the pool, creating a 30GB mirrored virtual disk is not possible since it will take at least 60GB of free space in the pool to create a mirrored virtual disk to hold the two copies of the mirrored data.
- Confirm the settings and initiate virtual disk creation by selecting “Create” on the “Confirm selections” page.
Step11: Add Disk to Azure Backup Server
- Launch Azure Backup Server and locate Disk Storage and Add – Select the disk, you want to add
- Once Added, this disk will be formatted with REFS file system and the storage will be available for Azure Backup Server.
