Zusammenfassung:A system for a distributed archive and data restoration which achieves both high-speed processing and security is provided. A random number is generated by a seed random number generator 443, and inputted to a key random number generator 445 as a seed, and each data fragment is obtained by dividing a source data file to be archived, and is redundantly stored on (h-k+1) storage mediums identified as destination storage mediums among n storage mediums on the basis of the random number generated by the key random number generator 445 each time.
