Abstract
Systems and methods for backing up data and for restoring at least sub-sets of the backed up data or for restoring sub-sets of data from a single file. An offset map is generated when backing up data. The offset map identifies at least starting locations of files and data records in the backup. A request for specific data is accommodated by identified the start locations of the specific data and then extracting the requested data from the backup. The requested data can then be restored independently of the entire backup.
