Abstract: A method, computer program product, and apparatus for managing file updates using content signatures that use file identicality properties are provided. A method and computer program product are provided for the notification of receipt of a new version of the old file using content signatures that take advantage of file identicality properties. Content signature application modules and registries exist within information source clients and centralized servers to support the notification methods. An apparatus is provided that associates a file it has received, that is a new version of an old file, with previously stored content signatures in an indexed archive system. The information source clients that have the previously stored content signatures are then identified. These information source clients are then notified that the new version of the file exists.

Abstract: Systems, methods and computer program products for distributed content storage and management are provided. The distributed content storage and management system includes an indexed archive system; information source agents, information source clients; and a network to couple the information source clients to the indexed archive system. In an alternate embodiment, a legacy back-up system is also used. The index archive system includes an information entryway for gathering file information, a triage engine, an indexing engine, a metadata engine, and a content engine. These engines generate content indexes, metadata and metadata indexes from received files and store them along with the file content into a set of repositories, including an indexing repository, a metadata repository and a content repository. Methods are provided for the efficient retrieval and indexing of files, and for the storage of files, file content, content indexes, metadata and metadata indexes.
