Abstract
A file management apparatus accommodates removable storage media that store index data for use by a file system. The file management apparatus is used to read and write in these removable storage media. An information processing apparatus obtains and holds index data of each removable storage medium from the file management apparatus, and uses the index data to distinguish files recorded in the removable storage media. The file management apparatus determines the right time to make a backup of index data, based on a recovery time objective that specifies a duration of time for recovery from a system failure, and sends out a timing message indicating the determined right time. In response, the information processing apparatus causes the file management apparatus to make a backup in a specified removable storage medium.
