Disable method of the MSFT_DedupVolume class

Disables further data deduplication activity on one or more volumes.

Syntax

uint32 Disable(
  [in]  string           Volume[],
  [in]  boolean          DataAccess,
  [out] MSFT_DedupVolume DedupVolume[]
);

Parameters

Volume [in]

A list of file system volumes for which to disable data deduplication. Volumes can be specified by drive letter (for example, D:) or volume GUID path. A volume GUID path is a string of the form "\\?\Volume{GUID}\" where GUID is a GUID that identifies the volume.

DataAccess [in]

Set to TRUE to cause data access to deduplicated files on the volume to be disabled.

DedupVolume [out]

Array of references to the disabled volumes.

Return value

This method returns either a WMI return code or a system error code.

Remarks

After data deduplication is disabled, the volume remains in its deduplicated state, but no more data deduplication jobs will be run for the specified volumes; new data will not be deduplicated. Previously deduplicated data is accessible. To undo deduplication on the volume, call the MSFT_DedupJob::Start method and pass Unoptimization for the Type parameter.

When a volume is Dedup-disabled, all read-only deduplication operations will continue to work (for example, the Get methods for deduplication class properties), but calls to deduplication job-related methods will fail, with the exception of unoptimization and read-only scrubbing jobs.

Examples

For an example that uses the Disable method, please see Data deduplication backup and restore sample.
