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

-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.

Aliases	Session

-DataAccess

Indicates that data access to deduplicated files on the volume is disabled.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-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.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-Volume<String[]>

Specifies an array of system volumes for which to disable data deduplication. Specify one or more volume IDs, drive letters (such as D:), or volume GUID pathnames (using the form \\?\Volume{{GUID}}\). Separate multiple volumes with a comma.

Aliases	Path,Name,DeviceId

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}\"
