Data management apparatus, data management method and data management program

摘要

There is disclosed a technique that can reliably erase data to achieve an enhanced level of security, while suppressing the problem of low operability and that of poor response of some other process due to an increased load. A data management apparatus for managing the data of a file system comprises a path information altering section for altering the contents of the path information indicating the location of the file to be erased according to a file erasing request for erasing the file so as to indicate a predetermined location, a task monitoring section for monitoring the state of the task being executed by the CPU adapted to execute processes relating to the file system and an erasing task executing section for executing an erasing task of erasing the real data of the file for which the contents of the path information are set to indicate the predetermined location according to the state being monitored by the task monitoring section at a time when no predetermined task other than the erasing task is being executed.
