- Microsoft Azure Backup Server requires SQL Server Standard, and the Azure Backup Server installation package comes bundled with the appropriate SQL Server binaries needed. When starting with a new Azure Backup Server installation, you should pick the option Install new Instance of SQL Server with this Setup and click the Check and Install button (Figure 11). Once the prerequisites are successfully installed, click Next.
Figure 11: SQL Settings
- If some of the prerequisites for SQL Server are not met, the installation will not continue and you’ll get a message like the one depicted in Figure 12. Click Cancel, install the necessary requisites and then re-launch the wizard. Hopefully, on the second time, the prerequisite check will pass with no errors (Figure 13). Click Next.

- Provide a location for the installation of Microsoft Azure Backup server files and click Next (Figure 14). The scratch location is a requirement for back up to Azure. Ensure the scratch location is at least 5% of the data planned to be backed up to the cloud. For disk protection, separate disks need to be configured once the installation completes. For more information regarding storage pools, see Configure storage pools and disk storage.

- 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. Click Next (Figure 18):
Figure 18: Proxy Configuration
Figure 19: Installation
Figure 20: Installation (cont.)
- The next step is to configure the Microsoft Azure Recovery Services Agent. As a part of the configuration, you will have to provide your vault credentials to register the machine to the backup vault. The vault credential file is downloaded through a secure channel from the Azure portal.
In the left navigation pane of the Azure Management Portal, click Recovery Services, and then select the backup vault that you created. On the Quick Start page, click Vault credentials (Figure 21).The portal generates a vault credential by using a combination of the vault name and the current date. The vault credentials file is used only during the registration process and expires after 48 hours.
Save the file to local disk and, back to the Register Server Wizard (Figure 22), browse to the file location and click Next.

- You will also provide a passphrase to encrypt/decrypt the data sent between Azure and your premises. You can automatically generate a passphrase or provide your own minimum 16-character passphrase (Figure 23). Click Next and continue with the wizard until the agent has been configured.
I got the error depicted on Figure 24. I tried once again by clicking Previous and Next, and the error went away.

- When the installation step has completed, the product's desktop icons will have been created as well. Just double-click the icon of Microsoft Azure Backup Server to launch the management console.
You need to add backup storage even if you plan to send data to Azure, since the first backup copy is kept on storage attached to the Azure Backup Server machine. In the current architecture of Azure Backup Server, the Azure Backup vault holds the second copy of the data while the local storage holds the first (and mandatory) backup copy.
- In Microsoft Azure Backup Console, in the Management task area, on the Disks tab, in the Actions pane, click Add (Figure 26). In case a warning pops-up stating that the disk will be converted to dynamic, click Yes. The disk will show up as belonging to the DPM storage pool (Figure 27).
Figure 26: Add Disks to Storage Pool

Azure Backup Server requires connectivity to the Azure Backup service for the product to work successfully. To validate whether the machine has the connectivity to Azure, use the Get-DPMCloudConnection cmdlet in the Azure Backup Server PowerShell console. If the output of the cmdlet is TRUE then connectivity exists (Figure 28), else there is no connectivity.
Figure 28: Get-DPMCloudConnection
At the same time, the Azure subscription needs to be in a healthy state. To find out the state of your subscription and to manage it, log in to the subscription portal (Figure 29).
Figure 29: Azure Management Portal
Once you know the state of the Azure connectivity and of the Azure subscription, you can use the table below to find out the impact on the backup/restore functionality offered.
|Connectivity State||Azure Subscription||Backup to Azure||Backup to disk||Restore from Azure||Restore from disk|
|Connected||Deprovisioned||Stopped||Stopped||Stopped and Azure recovery points deleted||Stopped|
|Lost connectivity > 15 days||Active||Stopped||Stopped||Allowed||Allowed|
|Lost connectivity > 15 days||Expired||Stopped||Stopped||Allowed||Allowed|
|Lost connectivity > 15 days||Deprovisioned||Stopped||Stopped||Stopped and Azure recovery points deleted||Stopped|

If you have a firewall or a proxy that is preventing access to Azure, you need to whitelist the following domain addresses in the firewall/proxy profile:
Configure the Agent
Before you continue, make sure that all the prerequisites for using Microsoft Azure Backup to protect workloads have been met. These prerequisites include the following:
- A backup vault on the Azure site has been created.
- Agent and vault credentials have been downloaded to the Azure Backup Server.
- The agent is installed on the Azure Backup Server.
- The vault credentials were used to register the Azure Backup Server.
To install the DPM protection agent (yes, it’s called DPM agent) on the Exchange server, open the Microsoft Azure Backup Server console, go to the Management pane and click Install to launch the agent installation wizard.
In some circumstances, you must install the protection agent manually, for example, when the computer that you want to protect is behind a firewall, in a workgroup, or in a domain that does not have a two-way trust relationship with the domain where the Azure Backup Server is located in. After manually installing an agent, you have to attach the computer in Microsoft Azure Backup Server console.
- To manually install the protection agent on the targeted computer, open an elevated Command Prompt window, and then run the following command, as depicted in Figure 31:\\<DPMServerName>\Program Files\Microsoft System Center 2012\DPM\DPM\ProtectionAgents\RA\4.1.<build number>.0\amd64\<language code>\DpmAgentInstaller_x64.exe <DPMServerName>
