ABSTRACT:
Data management systems and methods that can catalog, store, and protect data from hard disk failure on a mobile or stationary computer, using a computer program and a portable data storage device are provided. The program uses a combination message-digest and check-function based algorithm that can back up, manage, and protect data independent of specific computer operating system or file system. The program can check files for block-level content changes from previously stored data blocks and catalogs and stores only new data blocks. By storing only new data blocks and cataloging information within a comprehensive, backup archive composed of these blocks, the size of each backup is reduced.
