ABSTRACT:
Method and apparatus for backing up and restoring data in a computer system is disclosed. A segment of data, such as a virtual disk partition, may be backed up at a physical level from a primary storage device to a backup storage device. A logical element within the segment of data, such as a data file, may be restored from the backup storage device to the primary storage device. In one embodiment, this is achieved by restoring the segment to a scratch memory area and using a client computer to logically restore the logical element.
