DATA BACKUP AND RESTORAL APPARATUS, SYSTEM, AND METHODS

摘要

A method for maintaining incremental backups of a file. The method includes identifying a target file to be backed up. The method also includes comparing the target file to a one or more previously backed up files, in order to identify differences of the target file from a corresponding previously backed up file. The method also includes generating a delta version of the target file that records the identified differences from the previously backed up file.
