1. A data management apparatus for performing a generation management of backup data for a plurality of generations, comprising:
- a backup data storage control unit for making a write-once storage medium store by-generation backup data in order of generations; and
a generation identification data storage control unit for making an identification data stored for identifying a generation of the backup data at a storage position right in front of the by-generation backup data in the storage medium.
