[0058] figure 1 It is an explanatory diagram showing the basic structure of an embodiment of the present invention. As shown in the figure, the computer system of this embodiment is composed of a data center DC and a customer's computer connected to the data center DC through the Internet INT. In this embodiment, computer 100A of company A, computer 100B of company B, and computer 100C of company C are connected to data center DC. In the data center DC, a system 200A for company A, a system 200B for company B, and a system 200C for company C corresponding to each customer are installed, and a backup system BS for backing up data existing in these systems is installed. In addition, in this embodiment, the number of customer companies is taken as three, but it is not limited to this number.

[0059] The system 200A for Company A is constituted by interconnecting a router RT1, a Web server SV1, and a storage server S...

Abstract

To properly backup the data of each customer stored in a storage server while suppressing the illegal acquisition or leakage of data. SOLUTION: A data relay server 300 is provided with a function which receives a backup request from a backup management device 400 through a local area network LAN 4, and reads data stored in storage servers ST1 to ST3 in response to the request, and transfers the data to a media server 500. The data relay server 300 and the storage servers ST1 to ST3 are connected through a communication path through which not any Internet protocol but only the backup object data and control data attached to the data are allowed to pass.

Description

[0001] priority claim [0002] This application claims priority based on the patent application 2005-64690 filed in Japan on March 9, 2005. technical field [0003] The present invention relates to a technology for backing up data stored in each storage server in a computer system equipped with a storage server for each customer connected via the Internet. Background technique [0004] The storage server that stores the data used by the server or the client, it is very important to back up the data regularly in order to prevent the data from being lost. Data backup is performed on a predetermined recording medium by, for example, transferring the data to a storage server or a media server connected via fiber channel (see, for example, US Pat. No. 6,460,113). As the recording medium of the backup destination, for example, a transportable recording medium such as a magnetic tape medium, an optical disk, or a magneto-optical disk can be used, or a fixed storage medium such as ...
