Updated: January 4, 2013

Applies To: Windows Server 2012

Enable-DedupVolume

Enables data deduplication on one or more volumes.

Syntax

Parameter Set: Enable0
Enable-DedupVolume [-Volume] <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-DataAccess] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed 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.

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.

Specifies the maximum number of concurrent operations that can be established to run the cmdlet.

The throttle limit applies only to the current cmdlet, not to the session or to the computer.
