Windows Azure Backup is a feature that can automatically send backups of Windows Server to the Windows Azure cloud.
Before the backups are transmitted, they are encrypted. They will also be stored as encrypted files after reaching Windows Azure. Administrators can manage these backups to the cloud using the System Center 2012 Data Protection Manager, Windows Server 2012 or Windows Server 2012 Essentials. Administrators can use these tools to monitor, configure or recover backups to Windows Azure storage or on local disks.
According to Microsoft, Windows Azure Backup has limitations as to the volumes that will be backed up to the cloud. The volumes must be using NTFS and other file systems such as FAT32 will not work. The volumes must also be read-write because read-only volumes will not backup. If the volumes are already encrypted, they must be unencrypted before they can be backed up to Azure.
