Patent Images
1. A method comprising:
- reading volume configuration information from one or more storage devices, wherein the volume configuration information comprises a disk signature identifying a storage device of the one or more storage devices and is used to map a drive letter to the storage device, wherein a copy of the disk signature is stored in a registry item, and wherein the registry item is used to associate the drive letter and the disk signature; and
writing a copy of the volume configuration information read from the one or more storage devices to one or more backup storage devices, wherein the reading and the writing are both initiated by a virtualization module.
