Title (EN) ASYNCHRONOUS DISTRIBUTED DE-DUPLICATION FOR REPLICATED CONTENT ADDRESSABLE STORAGE CLUSTERS
(FR) DÉDUPLICATION RÉPARTIE ASYNCHRONE POUR DES GRAPPES DE MÉMOIRE ADRESSABLES À CONTENU RÉPLIQUÉ
Abstract:
(EN) A method is performed by a device of a group of devices in a distributed data replication system. The method includes storing an index of objects in the distributed data replication system, the index being replicated while the objects are stored locally by the plurality of devices in the distributed data replication system. The method also includes conducting a scan of at least a portion of the index and identifying a redundant replica(s) of the at least one of the objects based on the scan of the index. The method further includes de-duplicating the redundant replica(s), and updating the index to reflect the status of the redundant replica.
(FR) L'invention concerne un procédé exécuté par un dispositif d'un groupe de dispositifs dans un système de réplication de données réparties. Le procédé consiste à mémoriser un index d'objets dans le système de réplication de données réparties, l'index étant répliqué alors que les objets sont mémorisés localement par la pluralité de dispositifs dans ledit système. Le procédé consiste également à effectuer un balayage d'au moins une partie de l'index et à identifier une ou plusieurs répliques redondantes du ou des objets sur la base du balayage de l'index. Le procédé comprend en outre la déduplication de la ou des répliques redondantes et la mise à jour de l'index pour refléter l'état de la réplique redondante.
