Abstract

L'invention concerne un procédé de synchronisation de données, comprenant les étapes suivantes : recevoir une instruction de synchronisation de données envoyée par un terminal ; obtenir des données de copie de sauvegarde selon l'instruction de synchronisation de données ; dédupliquer des données à synchroniser selon les données de copie de sauvegarde de façon à obtenir des données cibles à synchroniser ; et envoyer les données cibles à synchroniser à un terminal de connexion se connectant au numéro de compte en nuage de façon à permettre au terminal de connexion d'effectuer la synchronisation de données. Un mode de réalisation de la présente invention concerne aussi un dispositif et un système de synchronisation de données, un support de stockage et un serveur.
