Explanation:
Download and install the Windows Azure Online Backup Agent After you create an account on the Windows Azure Online Backup website, you can download the Windows Azure Online Backup Agent and install it locally.
An Online Backup node then appears in the navigation pane of the Windows Server Backup console, as shown in Figure 12-

If you prefer, you can also configure online backups from the Windows Azure Online Backup console, which becomes available after you install the agent. The Windows Azure Online Backup console provides exactly the same set of options as the Online Backup node in the Windows Server Backup console.
Register server The next step is to register your server. Registering a server enables you to perform backups from that same server only. (Remember this point for the exam.) To register the server, from the Actions menu, select Register Server. The Register Server Wizard includes two configuration steps. First, you are given an opportunity to specify a proxy server if desired. Second, you are asked to provide a passphrase that will be used to encrypt your backup data and a location to save this passphrase in a file. You need to provide this passphrase when you perform a restore operation, so it’s essential that you don’t lose it.
(Microsoft doesn’t maintain a copy of your passphrase.) A Generate Passphrase option creates the passphrase for you automatically. After you register a server, new options for Online Backup appear in the Actions pane, including Schedule Backup, Recover Data, Change Properties, and Unregister Server.
