Summary:PROBLEM TO BE SOLVED: To provide a method and a device enabling a user to determine the suitable size of a journal area according to specific necessary conditions concerning a holding period for backup data. SOLUTION: A storage system implementing journaling for data backup and restore provides the user with information regarding amounts of journal data generated over periods of time. Dynamic allocation of storage capacity from free space may also be applied to the journal volume on an as-needed basis, and the size of the journal volume is minimized when certain journal input is determined to be no longer needed.
