Syntax

Enable-DedupVolume
      [-Volume] <String[]>

Description

The Enable-DedupVolume cmdlet enables data deduplication on one or more volumes . You can use the Set-DedupVolume cmdlet to customize the data deduplication settings. Data deduplication is disabled by default. Data deduplication is not supported for certain volumes, such as any volume that is not a NTFS file system or any volume that is smaller than 2 GB.

Examples

Example 1: Enable data deduplication on volumes

PS C:\>Enable-DedupVolume -Volume D:,E:,F:

This command enables data deduplication on volumes D:, E:, and F:.

Example 2: Enable data deduplication on a volume by using a GUID

PS C:\>Enable-DedupVolume -Volume "\\?\Volume{26a21bda-a627-11d7-9931-806e6f6e6963}\"

This command enables data deduplication for the volume that has the GUID 26a21bda-a627-11d7-9931-806e6f6e6963.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.
