Backup and Recovery Overview for Windows Server 2008

Shadow Copies of Shared Folders is a feature included in the Shared Folders Microsoft Management Console (MMC) snap-in that you or your users can use to view shared files and folders as they existed at points of time in the past. Accessing previous versions of files, or shadow copies, is useful because you can:

  • Recover files that were accidentally deleted. If you accidentally delete a file, you can open a previous version and copy it to a safe location.
  • Recover from accidentally overwriting a file. If you accidentally overwrite a file, you can recover a previous version of the file.
  • Compare versions of a file while working. You can use previous versions when you want to check what has changed between two versions of a file.

    However, creating shadow copies is not a replacement for creating regular backups. Also, you can only enable Shadow Copies of Shared Folders on a per-volume basis—that is, you cannot select specific shared folders and files on a volume to be copied or not copied.

    Shadow Copies of Shared Folders is available in all editions of Windows Server 2008 (both 32-bit and 64-bit versions). However, the Shadow Copies of Shared Folders user interface is not available for the Server Core installation option of Windows Server 2008.

    • If you plan to defragment the source volume on which Shadow Copies of Shared Folders is enabled, we recommend that you set the cluster allocation unit size to be 16 KB or larger when you initially format the source volume. If you do not, the number of changes caused by defragmentation can cause previous versions of files to be deleted.

    If you require NTFS file compression on the source volume, you cannot use an allocation unit size larger than 4 KB. In this case, when you defragment a volume that is very fragmented, you may lose older shadow copies faster than expected.

    • For instructions to enable and manage Shadow Copies of Shared Folders, see the local Help by typing the following command at a command prompt: hh scfs.chm .

    Windows Server Backup is a feature in Windows Server 2008 that provides a set of wizards and other tools for you to perform basic backup and recovery tasks for your servers running Windows Server 2008. This feature has been redesigned and introduces new technology. The previous backup feature (Ntbackup.exe) that was available with earlier versions of Windows has been removed.

    The Windows Server Backup feature in Windows Server 2008 consists of an MMC snap-in and command-line tools that provide a complete solution for your day-to-day backup and recovery needs. You can use four wizards to guide you through running backups and recoveries. You can use Windows Server Backup to back up a full server (all volumes), selected volumes, or the system state. You can recover volumes, folders, files, certain applications, and the system state. And, in case of disasters like hard disk failures, you can perform a system recovery by using a full server backup and the Windows Recovery Environment—this will restore your complete system onto the new hard disk.

    You can use Windows Server Backup to create and manage backups for the local computer or a remote computer. Also, you can schedule backups to run automatically.

    Windows Server Backup is intended for use by everyone who needs a basic backup solution—from small business owners to IT professionals in large enterprises. However, the design makes it especially well-suited for smaller organizations or individuals who are not IT professionals.

    You cannot recover backups that you created with Ntbackup.exe by using Windows Server Backup. However, a version of Ntbackup.exe is available as a download to Windows Server 2008 for users who want to recover data from backups created using Ntbackup.exe. The downloadable version of Ntbackup.exe is only for recovering backups for older versions of Windows and cannot be used to create new backups in Windows Server 2008. To download Ntbackup.exe, see http://go.microsoft.com/fwlink/?LinkId=82917 .

    • Windows Server Backup snap-in. This tool contains four wizards to help you perform backups and recoveries of your servers: Schedule Backup Wizard, Backup Once Wizard, Recovery Wizard, and Catalog Recovery Wizard. You can use the main page of the snap-in to view information about any past or future backup or recovery operations. Also, you can use the tool to configure performance options for backups and recoveries.
  • Wbadmin command-line tool. Windows Server Backup includes the Wbadmin command and documentation, which enable you to perform all of the same tasks at the command line that you can perform by using the snap-in. For more information, see the Command Reference (http://go.microsoft.com/fwlink/?LinkId=93131 ). You can also automate backup activities through scripting.
  • Windows PowerShell commands for Windows Server Backup. Windows Server 2008 contains a collection of Windows PowerShell commands (cmdlets) for Windows Server Backup that you can use to write scripts to perform backups. For more information, see http://go.microsoft.com/fwlink/?LinkId=93317 .

    Windows Server Backup is available in all editions of Windows Server 2008 (both 32-bit and 64-bit versions). However, the Windows Server Backup snap-in is not available for the Server Core installation option of Windows Server 2008. To run backups for computers with a Server Core installation, you need to either use the command line or manage backups remotely from another computer. In addition, Windows PowerShell is not available for the Server Core installation option, so the Windows PowerShell cmdlets for Windows Server Backup are also not available on this type of installation.

    Windows Server Backup supports external and internal hard disks, optical media drives, and removable media drives. You can no longer back up to tape—however, support of tape storage drivers is still included in Windows Server 2008. To perform a scheduled backup, as a best practice, use an external hard disk that supports either USB 2.0 or IEEE 1394.

    For more information about Windows Server Backup, see the following resources on the Microsoft Web site:

    • For instructions to install Windows Server Backup and to create backups and perform recoveries, see the local Help by typing the following command at a command prompt: hh backup.chm .
  • For information about Windows PowerShell commands (cmdlets) for Windows Server Backup, see http://go.microsoft.com/fwlink/?LinkId=93317 .
