Overview of Virtual Hard Disks

A virtual hard disk (VHD or VHDX) 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 or VHDX files (.vhd or .vhdx), which reside in container volumes, to run operating systems natively from VHDs or VHDXs. 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 or VHDX function independently of the VHD or VHDX where it resides.

Arcserve Backup protects the volumes mounted in VHDs or VHDXs.
