Enhanced Windows Server 2008 Backup Utility

Windows Server 2008  backup utility is completely different from the backup program included with Windows Server 2003. Unlike previous versions, the new utility is designed primarily to back up entire volumes to an external hard disk drive or to an UNC path. The backup utility also uses a different format for its backup files; it uses the Microsoft Virtual Hard Disk (VHD) format, which makes the files accessible to Hyper-V, Virtual PC, and the Complete PC backup utility. Windows Server 2008 backup utility allows you to backup entire drive or selected files or folder. You can perform complete backup or incremental backup. In addition to individual file and folder selection, the backup utility also enables you to create exclusions. An exclusion is a filter that prevents a job from backing up specified files or file types in the selected targets. There are three types of backup destination available in windows backup utility. these are dedicated hard disk drive, volume and UNC path.

System State and Bare Metal Backup

The System State includes the Windows Registry, the Active Directory database if the computer is a domain controller and a number of files that are locked open by the operating system. New windows backup utility enables you to individually select the System State element and a Bare Metal Recovery element. When you select bare metal backup, it will backup system partition and system state also. It will backup in .vhd format. 

To recover an entire computer, you connect your external hard drive containing the backup to the new computer and boot from the Windows Server 2008 R2 installation disk. Select Repair Your Computer in the Windows Setup Wizard>System Recovery Options>Restore Your Computer Using A System Image that you created earlier. Alternatively, you can import that .vhd file into Hyper-v if you desire to decommission physical machine.
