摘要

PROBLEM TO BE SOLVED: To realize file replication effective in data protection and efficient use of the data while maintaining availability of a system. SOLUTION: When the contents of a copy source file A1 are transferred to a computer B through a communication passage C as shown by a mark (a) by a file replication process PA in a copy source computer A, a file replication process PB writes the contents of the file A1 in copy destination files B1-BN of a disc DB in parallel as shown by marks b1-bN. The file replication process PB matches the contents of a new copy destination file with the contents of the file already designated as a copy destination when the number of copy destination files, in which writing is carried out in parallel, is increased.
