Method, system, and program for personal data management using content-based replication

摘要

Provided herein are data management systems and methods for storing, cataloging, and protecting data on a computer using software and a portable data storage device. The technology can back up, manage, and protect data for any operating or file system by checking files for block-level or byte-level changes and storing only new data. By storing only new data and cataloging information within a comprehensive backup archive composed of these blocks, the size of each backup is minimized.
