Returns a DeduplicationVolume object for each volume that has data deduplication metadata.

Syntax

Parameter Set: ByVolumeId
Get-DedupVolume [-AsJob] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [-VolumeId <String[]> ] [ <CommonParameters>]

Parameter Set: ByVolume
Get-DedupVolume [[-Volume] <String[]> ] [-AsJob] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The Get-DedupVolume cmdlet returns a DeduplicationVolume object for each volume that has data deduplication metadata (in either the enabled or disabled state). In a cluster, this cmdlet returns a DeduplicationVolume object only for volumes currently mounted by the managed node (whether the volumes are local or clustered volumes).

To run this cmdlet, you must start Windows PowerShell® with the Run as administrator option.

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.
