Abstract
A system and method for generating a virtual full synthetic backup of a target volume is described. For each zone associated with the target volume in which a corresponding data block has changed since the previous backup or is not represented by the previous backup, the system and method may directly copy the associated data blocks from the target volume. For each zone associated with the target volume in which a corresponding data block has not changed since the previous backup and is represented by the previous backup, the system and method may rebase the offset for the zone in the virtual full synthetic backup file to the corresponding zone in the previous backup file. Using this technique, a more efficient and robust backup may be generated.
