VirtualDiskSeSparseBackingInfo

VirtualDiskSeSparseBackingInfo
VirtualDiskSeSparseBackingInfo

Backing type for virtual disks that use the space efficient sparse format.

Space for space efficient sparse disks is allocated on demand and optimizations are applied to achieve additional space savings. The effective space usage of such a disk can be obtained from VirtualMachineFileLayoutEx.

}
string
diskMode
Required

The disk persistence mode.

Valid modes are:

See also VirtualDiskModeEnum.

boolean
writeThrough
Optional

Flag to indicate whether writes should go directly to the file system or should be buffered.

string
uuid
Optional

Disk UUID for the virtual disk, if available.

string
contentId
Optional

Content ID of the virtual disk file, if available.

A content ID indicates the logical contents of the disk backing and its parents.

This property is only guaranteed to be up to date if this disk backing is not currently being written to by any virtual machine.

The only supported operation is comparing if two content IDs are equal or not. The guarantee provided by the content ID is that if two disk backings have the same content ID and are not currently being written to, then reads issued from the guest operating system to those disk backings will return the same data.

string
changeId
Optional

The change ID of the virtual disk for the corresponding snapshot or virtual machine.

This can be used to track incremental changes to a virtual disk. See QueryChangedDiskAreas.

VirtualDiskSeSparseBackingInfo
parent
Optional

Backing type for virtual disks that use the space efficient sparse format.

Space for space efficient sparse disks is allocated on demand and optimizations are applied to achieve additional space savings. The effective space usage of such a disk can be obtained from VirtualMachineFileLayoutEx.

string
deltaDiskFormat
Optional

The format of the delta disk.

This field is valid only for a delta disk.

See DeltaDiskFormat for the supported formats. If not specified, the default value used is redoLogFormat.

boolean
digestEnabled
Optional

Indicates whether the disk backing has digest file enabled.

integer As int32 As int32
grainSize
Optional

Specify the grain size in kB.

The default size is 4 kB.

CryptoKeyId
keyId
Optional

Data Object representing a cryptographic key.
