A repository file space in the first file system is used to accomplish the storage of some or all of the management classes or attributes for the files of the second file system. For each file in the second file system an empty file is created in the repository file space of the first file system. The creation of an empty file in the repository file space causes a management class to be selected for the file and stored in the catalog of the first file system as would be done for any file in the first file system. A naming convention is used to link each file in the repository file space with its associated file in the second file system. The additional files in the first file system are left empty as no other information need be stored for storage management purposes. The management attributes of the files are then compared to the management criteria represented by the management classes stored in the catalog of the first file system and the files are managed accordingly. | |
