Properties

The MSFT_DedupVolumeStatus class has these properties.

Capacity

Data type: uint64

Access type: Read-only

The capacity of the volume, in bytes.

FreeSpace

Data type: uint64

Access type: Read-only

The amount of free space on the volume, in bytes.

InPolicyFilesCount

Data type: uint64

Access type: Read-only

The number of files that currently qualify for optimization. This number will stay relatively constant between optimization jobs.

InPolicyFilesSize

Data type: uint64

Access type: Read-only

The aggregate size of all files that currently qualify for optimization. This number will stay relatively constant between optimization jobs.

LastGarbageCollectionResult

Data type: uint32

Access type: Read-only

The error code from when a garbage collection job was run last on the volume. A value of zero means the job ran successfully.

LastGarbageCollectionResultMessage

Data type: string

Access type: Read-only

The error message from when a garbage collection job was run last on the volume. A null value or empty string means the job ran successfully.

LastGarbageCollectionTime

Data type: datetime

Access type: Read-only

The date and time when a garbage collection job was run last on the volume. This date and time will stay constant between garbage collection jobs.

LastOptimizationResult

Data type: uint32

Access type: Read-only

The error code from when an optimization job was run last on the volume. A value of zero means the job ran successfully.

LastOptimizationResultMessage

Data type: string

Access type: Read-only

The error message from when an optimization job was run last on the volume. A null value or empty string means the job ran successfully.

LastOptimizationTime

Data type: datetime

Access type: Read-only

The data and time when an optimization job was run last on the volume. This date and time will stay constant between optimization jobs.

LastScrubbingResult

Data type: uint32

Access type: Read-only

The error code from when a scrubbing job was run last on the volume. A value of zero means the job ran successfully.

LastScrubbingResultMessage

Data type: string

Access type: Read-only

The error message from when a scrubbing job was run last on the volume. A null value or empty string means the job ran successfully.

LastScrubbingTime

Data type: datetime

Access type: Read-only

The data and time when a scrubbing job was run last on the volume. This date and time will stay constant between scrubbing jobs.

OptimizedFilesCount

Data type: uint64

Access type: Read-only

The number of optimized files on the volume. Note that this number will remain steady (instead of decrease) as users delete files from, or add files to, the volume until you run a garbage collection job. This count is most accurate after a garbage collection job runs.

OptimizedFilesSavingsRate

Data type: uint32

Access type: Read-only

The ratio of deduplication saved space to the logical size of all optimized files on the volume, expressed as a percentage. Note that this number will remain steady as users delete files from, or add new files to, the volume-until you run an optimization job or execute the Update method of the MSFT_DedupVolumeStatus class. This number is most accurate after an optimization job runs or the Update method is executed.

OptimizedFilesSize

Data type: uint64

Access type: Read-only

The aggregate size of all optimized files on the volume. Note that this number will remain steady (instead of decrease) as users delete files from, or add new files to, the volume until you run a garbage collection job. This number is most accurate after a garbage collection job runs.

SavedSpace

Data type: uint64

Access type: Read-only

Saved space is the difference between the logical size of the optimized files and the logical size of the store (the deduplicated user data plus deduplication metadata). Note that this number will remain steady as users delete files from, or add new files to, the volume until you run an optimization job or execute the Update method. This number is most accurate after an optimization job runs or the Update method is executed.

SavingsRate

Data type: uint32

Access type: Read-only

The ratio of deduplication saved space to the logical size of all of the files on the volume and is expressed in percentage. Note that this number will remain steady as users delete files from, or add new files to, the volume until you run an optimization job or execute the Update method. This number is most accurate after an optimization job runs or the Update method is executed.

UnoptimizedSize

Data type: uint64

Access type: Read-only

The total logical size of all files on the volume, in bytes. This includes all files, optimized and non-optimized. Note that this number will remain steady as users delete optimized files from the volume-until you run an optimization job or execute the Update method of the MSFT_DedupVolumeStatus class. This number is most accurate after an optimization job runs or the Update method is executed.

UsedSpace

Data type: uint64

Access type: Read-only

The amount of used space on the volume, in bytes.

Volume

Data type: String

Access type: Read-only

A drive letter (for example, D:) or volume GUID path for the volume.

VolumeId

Data type: String

Access type: Read-only

Qualifiers: key

A volume GUID path for the volume. A volume GUID path is a string of the form "\\?\Volume{GUID}\" where GUID is a GUID that identifies the volume.
