Abstract
A system, apparatus, and process creates a table of contents (TOC), including one or more table of contents (TOC) entries, to manage data in a hierarchical storage management system. Each TOC entry contains metadata describing the contents and attributes of a data object within an image, which is an aggregation of multiple data objects into a single object for storage management purposes. The TOC is stored in a storage hierarchy, such as magnetic disk, for fast access of and efficient operation on the aggregated TOC entries. The system, apparatus, and process also provide for aggregating the TOC entries from one or more TOCs into a TOC set in the storage management server database. The TOC set may be manipulated and queried in order to find a particular data object or image referenced by a TOC entry. The TOC entries, TOCs, and TOC sets may be dynamically managed by the hierarchical data storage management system through implementation of a set of policy management constructs that define appropriate creation, retention, and movement of the objects within the database and storage hierarchy.
