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.
