Abstract

A method and apparatus for supplying information, and a storage medium on which an information supplying program is stored are disclosed, in which backup files of Web pages which were laid open in the past and those which will be laid open in the future are stored in a WWW server so that any Web page can be presented to a client in response to a request issued by the client. WWW server creates a file name used as a key when being retrieved, by adding data representing updating date and time at the end of an original file name of a Web page stored in an open storage area of an HDD which is allowed to be freely accessed via the Internet. The created file name serving as a key in retrieval is assigned to a backup data created from update data, and the backup data is stored in a retrieval storage area. In response to a request issued by a client via the Internet, the WWW server retrieves backup data having a file name corresponding to specified date and time from the retrieval storage area and transfers the retrieved backup data to the client.

Claims

1. A method of supplying information, comprising:

a data updating step in which data stored in an open storage area allowed to be freely accessed via a network is replaced with update data at a specified time;

a data backing-up step in which a retrieval file name is produced by adding data, which represents a date and time when updating should be performed, to the file name of said update data, said file name is assigned to backup data produced from said update data, and said backup is saved in a retrieval storage area; and

a retrieving step in which backup data having a file name corresponding to an updating time specified via said network is retrieved from said retrieval storage area, and the retrieved data is transferred via said network to a client which has requested said data.
