Disable-DedupVolume

Updated: January 4, 2013

Applies To: Windows Server 2012

Disable-DedupVolume

Disables data deduplication activity on one or more volumes.

Syntax

Parameter Set: Disable1
Disable-DedupVolume [-Volume] <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-DataAccess] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The Disable-DedupVolume cmdlet disables further data deduplication activity on one or more volumes. After you disable data deduplication, the volume remains in a deduplicated state and the existing deduplicated data is accessible. The server stops running data deduplication jobs for the volume and new data is not deduplicated. To undo data deduplication on a volume, use the Start-DedupJob cmdlet and specify Unoptimization for the Type parameter.

After you disable data deduplication on a volume, you can perform all read-only deduplication cmdlet operations on the volume. For example, you can use the Get-DedupStatus cmdlet to get deduplication status for a volume that has data deduplication metadata. After you disable data deduplication on a volume, you cannot use the data deduplication job-related cmdlets and the Update-DedupStatus cmdlet to perform operations on the volume. For example, you cannot use Start-DedupJob to start a data deduplication job for a volume on which you have disabled data deduplication.

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<CimSession[]>

-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.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • System.String[]

Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.Management.Infrastructure.CimInstance#

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.


Examples

Example 1: Disable data deduplication on volumes

This command disables data deduplication for volumes D:, E:, F:, and G:.


PS C:\> Disable-DedupVolume -Volume D:,E:,F:,G:

Example 2: Disable data deduplication on a volume by using a GUID

This command disables data deduplication for the volume that has the GUID 26a21bda-a627-11d7-9931-806e6f6e6963.


PS C:\> Disable-DedupVolume –Volume "\\?\Volume{26a21bda-a627-11d7-9931-806e6f6e6963}\"
