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 navigationpane 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.) Toregister the server, from the Actions menu, selectRegister
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 its essential that you dontlose it. (Microsoft doesnt maintain a copy of your passphrase.)
A Generate Passphrase option creates the passphrasefor you automatically.
After you register a server, new options for OnlineBackup appear in the Actions pane, including Schedule
Backup, Recover Data, Change Properties, and Unregister Server.
