L'invention concerne un procédé et un appareil de sauvegarde de données. Le procédé comprend les étapes consistant à : déterminer une application nécessitant une sauvegarde de données et déterminer au moins un dispositif de stockage qui stocke les données de l'application (S200) ; figer les E/S de disque correspondant à chacun desdits au moins un dispositif de stockage (S210) ; pour chacun desdits au moins un dispositif de stockage, ordonner à un dispositif de sauvegarde d'effectuer une sauvegarde de données pour l'application (S220) ; et après avoir déterminé que le dispositif de sauvegarde a terminé la sauvegarde de données pour l'application, restaurer les E/S de disque correspondant à chaque dispositif de stockage (S230). Dans la présente invention, un agent hôte assure la cohérence des données d'application en figeant les E/S de disque. Il suffit d'interfacer le dispositif de sauvegarde avec l'agent hôte par l'intermédiaire d'une interface sud standard, et le dispositif de sauvegarde n'a pas besoin d'effectuer d'actions de pré-traitement de sauvegarde et de post-traitement de sauvegarde particulières pour une application de couche supérieure, ce qui réduit la complexité et améliore l'efficacité de la sauvegarde de données.
