Module:
deduplication
Returns deduplication status for volumes that have data deduplication metadata.

Syntax 

Get-DedupStatus
   [[-Volume] <String[]>]
   [-CimSession <CimSession[]>]
   [-ThrottleLimit <Int32>]
   [-AsJob]
   [<CommonParameters>]

Description

The Get-DedupStatus cmdlet returns a deduplication status object for every volume that has data deduplication metadata. A DeduplicationStatus object includes read-only properties that describe capacity, free or used space and optimization savings and status on the volume, times, and completion status for the last jobs on the volume.

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

Examples

Example 1: Get status for specified volumes 

PS C:\> Get-DedupStatus -Volume "D:","F:"

This command gets deduplication status for the D: and F: volumes.

Optional 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 .

-CimSession

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