Enable-DedupVolume
Updated: January 4, 2013
Applies To: Windows Server 2012
Enable-DedupVolume
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.

-ThrottleLimit<Int32>
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. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
