Abstract

L'invention concerne un procédé et un dispositif de sauvegarde de données, ainsi qu'un support d'informations lisible par ordinateur. Ledit procédé peut consister : à acquérir, au moyen d'un serveur, une demande de sauvegarde d'un premier utilisateur envoyée par un terminal (101) et l'identifiant d'identité du premier utilisateur (S301), la demande de sauvegarde servant à demander une sauvegarde de premières données à sauvegarder du premier utilisateur ; à déterminer, au moyen du serveur (102), un programme de sauvegarde en fonction de l'identifiant d'identité et de la demande de sauvegarde (S302), le programme de sauvegarde comprenant un ou plusieurs éléments parmi un système de stockage de sauvegarde, le nombre de sauvegardes, un système de stockage principal et un temps de retard de sauvegarde ; à établir, au moyen du serveur, selon le programme de sauvegarde, une connexion entre le système de stockage principal et un système de stockage de sauvegarde correspondant dans un réseau de chaîne de blocs (S303) ; et à sauvegarder, au moyen du serveur, lesdites premières données dans le système correspondant de stockage de sauvegarde (S304). La solution ci-dessus peut réaliser une sauvegarde automatique selon des exigences d'utilisateur, en améliorant sensiblement l'efficacité de sauvegarde de données d'utilisateur.
