Selective backup (in which most of the volume is being backed up) may also benefit from using the optimized backup approach if the logical size of the selected files is significantly greater than the physical size of the optimized files plus the chunk store container files. Optimized backups are faster because there is less I/O and because the optimized files are not restoredrehydrated during the file copy operations. The backup is smaller because the total size of the optimized files, non-optimized files (files that are not included in policies), and data deduplication chunk store files are significantly smaller than the full logical size of the volume (that is, the size of all the files before deduplication). Performing an optimized backup results in a smaller, faster backup. Restore a particular folder (in this case, the E:\Docs folder): C:\> Wbadmin start recovery –version:-06:22 -itemtype:File -items:E:\Docs -recursive Restore the entire volume: C:\> Wbadmin start recovery –version:-06:22 -itemtype:Volume -items:E: -recoveryTarget:E: This output version ID will be a date and time string, for example: -06:22. Get the version ID of the backup you just created: C:\> wbadmin get versions To back up the E: volume to another volume, run the following from a command prompt, substituting the correct volume names for your situation: C:\> wbadmin start backup –include:E: -backuptarget:F: -quiet Install Windows Server Backup by running the following Windows PowerShell command: PS C:\> Add-WindowsFeature -name Windows-Server-Backup

The following examples show how to back up a volume and how to restore a volume or selected files from a volume. Windows Server Backup has the ability to back up an optimized volume “as-is” (that is, without removing deduplicated data). Data Deduplication may be modifying data, and this could cause data loss.
Do not attempt to manually back up the reparse points and the deduplication chunk-store files that are located in the hidden Sysvol folder by using Robocopy.
