VMware describes VDDK as “a set of libraries and utilities that enable software developers to create applications that can access and manipulate virtual disks” and “a valuable tool for developers of storage and backup applications.”
Users, along with VMware’s rivals, had another use for VDDK: migrating VMs to alternative virtualization platforms.
