Title: (DE) SYNCHRONISATION VON SCHNAPPSCHÜSSEN ZWISCHEN SPEICHERSYSTEMEN
(EN) SYNCHRONIZING SNAPSHOTS BETWEEN STORAGE SYSTEMS
(FR) SYNCHRONISATION D'INSTANTANÉS ENTRE DES SYSTÈMES DE STOCKAGE
Abstract:
(EN) Synchronizing snapshots between storage systems, including: receiving, from a source storage system, an identification of a snapshot to be replicated to a destination storage system; identifying, from hint information stored on the destination storage system, a most recent version of the snapshot that is stored on the destination storage system; issuing, to the source storage system, a request for an identification of the differences between the snapshot to be replicated to the destination storage system and the most recent version of the snapshot that is stored on the destination storage system; receiving, from the source storage system, the identification of the differences; and issuing a request to transfer, from the source storage system to the destination storage system, data associated with the differences.
(FR) L'invention concerne la synchronisation d'instantanés entre des systèmes de stockage consistant à : recevoir, d'un système de stockage source, une identification d'un instantané à répliquer dans un système de stockage de destination; identifier, à partir des informations d'indication stockées dans le système de stockage de destination, la version la plus récente de l'instantané qui est stockée dans le système de stockage de destination; générer, vers le système de stockage source, une demande d'identification des différences entre l'instantané à répliquer dans le système de stockage de destination et la version la plus récente de l'instantané qui est stockée dans le système de stockage de destination; recevoir, du système de stockage source, l'identification des différences; et générer une demande de transfert, du système de stockage source vers le système de stockage de destination, des données associées aux différences.
