Overview of Virtual Hard Disks

A virtual hard disk (VHD) is an image format that contains the contents of a disk and virtual operating systems and their associated applications in a single file using virtualization methodologies. Thus, you can use VHD files (.vhd), which reside in container volumes, to run operating systems natively from VHDs. Container volumes can include a collection of operating system files, data files, drivers, and so on that let the operating system mounted in the VHD function independently of the VHD where it resides.

CA ARCserve Backup protects the volumes mounted in VHDs.
