摘要

A data management system and a method of data management for managing the storage of data on primary and secondary storage is disclosed. The data management system for managing the storage of data on primary and secondary storage from a primary information source having original file content to be stored includes a data file stub stored on primary storage and a data file stored on secondary storage. The data file stub comprises original file meta data and additional stub meta data relevant to the data file. The data file comprises the original file content and additional file meta data relevant to the data file stub where the additional stub meta data includes location and information relevant to locate and recover the data file. The additional file meta data includes information relevant to the location and content of the stub where the additional stub meta data and additional file meta data is formed and arranged such that data to be stored may be accessed without stateful middleware.
