Get-DedupStatus
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
Get-DedupStatus -Volume "D:","F:"This command gets deduplication status for the D: and F: volumes.
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. 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.
