Title (EN) FAST AND LOW-RAM-FOOTPRINT INDEXING FOR DATA DEDUPLICATION
(FR) INDEXATION D'OCCUPATION DE MÉMOIRE VIVE RAPIDE ET LENTE POUR UNE DÉDUPLICATION DE DONNÉES
Abstract: front page image
(EN)The subject disclosure is directed towards a data deduplication technology in which a hash index service's index maintains a hash index in a secondary storage device such as a hard drive, along with a compact index table and look-ahead cache in RAM that operate to reduce the I/O to access the secondary storage device during deduplication operations. Also described is a session cache for maintaining data during a deduplication session, and encoding of a read-only compact index table for efficiency.
(FR)L'invention concerne une technologie de déduplication de données dans laquelle un index de service d'index de hachage gère un index de hachage dans un dispositif de stockage secondaire tel qu'un disque dur, ainsi qu'une table d'index compacte et un cache à lecture anticipée dans la mémoire vive qui permet de réduire l'E/S pour accéder au dispositif de stockage secondaire pendant les opérations de déduplication. L'invention concerne également un cache de session permettant de gérer des données pendant une session de déduplication, et de coder une table d'index compacte en lecture seule pour plus d'efficacité.
