Get-DedupStatus

Returns deduplication status for volumes that have data deduplication metadata.

Syntax

Parameter Set: Query (cdxml)
Get-DedupStatus [[-Volume] <String[]> ] [-CimSession <CimSession[]> ] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed 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.

Parameters

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

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