Windows Azure Backup helps you protect important server data off-site with automated backup and restoration.
You can manage cloud backups from familiar backup tools in Windows Server 2012, Windows Server 2012 Essentials, or the Data Protection Manager component of Microsoft System Center 2012 Service Pack 1 (SP1). Authorized users can easily recover backups to any server.
With incremental backups, only changes to files are transferred to the cloud. This helps ensure efficient use of storage, reduced bandwidth consumption, and point-in-time recovery of multiple versions of the data. Configurable data retention policies, data compression, and data transfer throttling offer you added flexibility and help boost efficiency. Backups are stored in Windows Azure and are “off-site”, reducing the need to secure and protect on-site backup media.
Windows Azure Backup is billed in units based on your average daily amount of compressed data stored over a monthly billing period, at a rate of $0.25 per gigabyte (GB) per month during preview. Once Backup is generally available, it will be billed at $0.50 per GB per month.
