Recovery of a computer that includes virtual disks
First Claim
1. In a computing environment having a computing device, a system comprising, a restore mechanism, including a mechanism that re-creates a physical disk based upon metadata maintained at a backup time of the computing device, and a mechanism that re-creates a virtual disk on the physical disk, wherein the virtual disk is a file in a format that allows the file to be used as a disk device and re-creating the virtual disk includes determining that the virtual disk is associated with a first nesting level, and re-creating the virtual disk and another virtual disk at a second nesting level in a layered order based on each virtual disk'"'"'s associated level.

Abstract
Described is the backup and/or restore of virtual disks In general, metadata is backed up for restoring a virtual disk. To restore the disk, a physical disk is created, with the virtual disk the created on a partition of the physical disk. Backup and restore is described for nested virtual disks, including for block level restore. Further described is backing up of critical virtual disks and their containers, and virtual disk backup with respect to basic disks and dynamic volumes.
