| Summary: | By considering a device life and time needed for data migration, data stored in a storage apparatus is securely preserved until a retention term of each of the data. Multiple disk devices A to C that store a data file generated by a service server apparatus are included. A migration manager of a management server apparatus acquires preservation period information that indicates a preservation period of the data file from the service server apparatus , and calculates a preservation term of the data file based on the preservation period information. The migration manager of the management server apparatus also acquires data amount information of the data file from the service server apparatus , and calculates a necessary time needed for migrating the data file to other disk devices AA to C. When the preservation term comes later than an operation guarantee term recorded in advance for each of the disk devices A to C, the migration manager of the management server apparatus compares the end of the migration with the operation guarantee term, and determines the necessity of the migration. |
