DATA ALLOCATION DEVICE, DATA ALLOCATION METHOD AND DATA ALLOCATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To suppress the variation of processing loads among servers.

SOLUTION: A management server 10 includes an acquisition part 13a for acquiring the number of a plurality of execution servers 1 to N which execute the distributed processing of data after prescribed data are equally divided. When one device is excluded from the execution object of the distributed processing, the execution servers 1 to N process first backup data. When two devices are excluded from the execution object of the distributed processing, the execution servers 1 to N process second backup data. The management server 10 includes an allocation determination part 13d for determining the allocation of the second backup data according to the number of the execution servers 1 to N. The allocation determination part 13d determines allocation such that prescribed allocation is not overlapped with the same device. The prescribed allocation includes data whose processing is executed by the second server instead of the first server and data whose processing is executed by the first server instead of the second server.
