Embodiment Construction

[0018] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings below.

[0019]FIG. 1 shows a configuration of a backup storage service system according to an embodiment of the present invention. In the system of FIG. 1, a management service provider corporation (hereinafter denoted as a MSP) provides data backup service to users (hereinafter denoted as USRs) by using idle resources of a plurality of storage service provider corporations (hereinafter denoted as SSPs). Each SSP has a SSP server 103 which is a computer environment on the storage service side. Each USR has a USR server 102 which is a computer environment on the user side. A MSP server 101 is computing means which interfaces between the two computer environments in order to support the storage service.

[0020] In FIG. 1, the MSP server 101 receives data from USR servers 102-1 and 102-2, divides the data into records and stores the records in idle resources manag...

Abstract

User data backup functions are realized through a computer, which is located on the management service provider corporation side and interfaces between a user side computer environment and a storage service side computer environment to support storage service. This computer selects storage devices which meet the user side conditions from a plurality of entirely or partially empty storage devices owned by the storage service side computer environment. The computer receives user data from the user side computer environment, divides the user data into records of a predetermined size and transmits the records to the storage service side computer environment so that the records are distributed and stored to the selected storage devices.

Description

[0001] The present application is a continuation of application Ser. No. 10 / 367,767, filed Feb. 19, 2003, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates to storage backup techniques, and more particularly, to a technique for backing up storage in a remote place. [0003] Since contents of disk storage may be lost-by an unexpected accident, data backup is made in most computer systems. Further, data backup tape and other media are kept in a remote site so that they will not be lost together with the original copies in case of a fire, earthquake or the like. Accordingly, a SAN (storage area network)-used backup method is disclosed in Japanese Patent Laid-open No. 2002-7304. Also in Japanese Patent Laid-open No. 2000-82008, a data sharing-based backup method is disclosed. [0004] Large-scale earthquakes, synchronized attacks by viruses, etc. prove a further growing threat to computer systems and their data, which...
