Abstract:
A storage control system including an overlap retrieval arrangement for retrieving overlap files, which are stored in at least one storage area of a plurality of storage areas, and which overlap one another, and a storage controlling arrangement for storing data of at least one overlapped part of the retrieved overlap files in a storage area having reliability that is greater than that of the storage area in which the data of this overlapped part is stored. A large number of files are stored in a plurality of storage areas, and the overlap retrieval arrangement retrieves overlap files from among a number of files, which is smaller than the number of stored files.
