Properties

The Win32_ShadowCopy class has these properties.

ClientAccessible

Data type: boolean
Access type: Read-only

If true, the shadow copy is created by the Windows Previous Versions component.

Count

Data type: uint32
Access type: Read-only

Number of shadow copies in a shadow copy set to which a shadow copy belongs.

DeviceObject

Data type: string
Access type: Read-only

Windows object manager name for an underlying storage device that supports the original volume.

Differential

Data type: boolean
Access type: Read-only

If true, the shadow copy is created by a differential shadow copy provider. The provider can be implemented in hardware or software.

ExposedLocally

Data type: boolean
Access type: Read-only

If true, the shadow copy is exposed on the local computer with a drive letter or mount point. If ExposedLocally and ExposedRemotely are not set, the shadow copy is hidden.

ExposedName

Data type: string
Access type: Read-only

File system name of a shadow copy when it is exposed. The ExposedName property might contain a drive letter or mount point. The ExposedName property is NULL when a shadow copy is hidden or otherwise not exposed.

ExposedRemotely

Data type: boolean
Access type: Read-only

If true, the shadow copy is exposed on a remote computer with a network share. If ExposedRemotely and ExposedLocally are not set, the shadow copy is hidden.

HardwareAssisted

Data type: boolean
Access type: Read-only

If true, the shadow copy is created by a hardware shadow copy provider.

ID

Data type: string
Access type: Read-only

Unique identifier for a shadow copy on the system.

Imported

Data type: boolean
Access type: Read-only

If true, the shadow copy is imported to a computer by using the Import method and is not created by using the Create method.

NoAutoRelease

Data type: boolean
Access type: Read-only

If true, the shadow copy is retained after the requestor process ends. If false, the shadow copy is automatically deleted when the requestor process ends.

NotSurfaced

Data type: boolean
Access type: Read-only

If true, the shadow copy is not currently in the device namespace of a local computer.

NoWriters

Data type: boolean
Access type: Read-only

If true, the shadow copy is created with the involvement of the shadow copy writer components.

OriginatingMachine

Data type: string
Access type: Read-only

Name of the computer that hosts the original volume.

Persistent

Data type: boolean
Access type: Read-only

If true, the shadow copy is persistent across reboots.

Plex

Data type: boolean
Access type: Read-only

If true, the shadow copy is created by a split mirror shadow copy provider. The provider can be implemented in hardware or software.

ProviderID

Data type: string
Access type: Read-only

Unique identifier for a shadow provider that creates a shadow.

ServiceMachine

Data type: string
Access type: Read-only

Name of the computer that services the shadow copy.

SetID

Data type: string
Access type: Read-only

Unique identifier for a shadow copy set to which the shadow belongs.

State

Data type: uint32
Access type: Read-only

Current state of a shadow copy.

Value	Meaning
