A method and system for parallel, system managed storage for objects on multiple servers

摘要

A distributed storage system is disclosed in which an originating storage location establishes the criteria for storage management for a file. When the file is transmitted to other, subsidiary storage locations, it is accompanied by information controlling the storage of the file. For example, the duration of storage will be controlled by the control information. When a master file is deleted from an archive, in accordance with the criteria established at the time of storage, copies of the file at subsidiary locations can either be rendered inaccessible or alternately the storage management for that file can be changed. A feature is the distribution of storage management control information along with the file to diverse storage locations in a complex data processing system.
