File Version Retrieval via Capture Manifest Indexing

The patent segments the capture data into discrete blocks and creates an index structure that maps file metadata to specific block locations. This allows the retrieval system to access only the specific blocks containing the requested file or file version, rather than reconstituting entire captures. The segmentation enables selective retrieval by breaking down the monolithic capture structure into accessible, addressable units.

The patent performs preliminary actions by pre-processing capture data during the capture phase: organizing data into blocks, generating metadata, and creating an index structure that maps files to block locations. This preliminary organization is stored in the data store, enabling rapid retrieval operations later without requiring reconstitution of entire captures. The index structure is built in advance to facilitate efficient querying and selective block retrieval.

The patent extracts only the specific blocks containing the requested file or file version from the captured data, rather than processing entire captures. The index structure enables the retrieval system to identify and extract only the necessary blocks, leaving the rest of the capture data untouched. This extraction approach maintains data integrity for the retrieved portions while avoiding the computational overhead of processing complete captures.

The patent applies partial action by retrieving only the specific blocks needed for the requested file, rather than performing the excessive action of reconstituting entire captures. The index structure enables precise identification of the subset of blocks required, allowing the system to perform exactly the amount of work necessary (partial action) rather than the full reconstitution process (excessive action), thereby reducing computational resource usage while maintaining the integrity of the retrieved data.
