Abstract:
A computer implemented method is disclosed for obtaining file-level information from block level information of files stored on a storage medium. The method includes accessing the storage medium to obtain metadata available in block level on the storage medium and building an inverse block-to-file map of the files stored on the storage medium. The method also includes listening online to incoming block-level commands communicated from a host to the storage medium, parsing the incoming block-level commands, inferring file-level information from the parsed block level commands; and updating the inverse file-level map. Also disclosed are corresponding computer program product and processing system.
