Versioning simplifies vDisk update and management tasks, providing a more flexible and robust approach to managing vDisks.
A vDisk consists of a VHD base image file, any associated side-car files, and if applicable, a chain of referenced VHD differencing disks. Differencing disks are created to capture the changes made to the base disk image, leaving the original base disk unchanged. Each differencing disk that is associated with a base disk represents a different version.
The following illustrates the file naming convention used and the relationship between a a base disk and all versions referencing that base disk.
|VHD Filename||Properties Filename||Lock File Filename|
