Abstract: Procédé et appareil de clonage d'un système de fichiers. Dans le procédé, un système de stockage de destination reçoit d'abord des premières informations en provenance d'un système de stockage source exécutant un système de fichiers, les premières informations étant utilisées pour indiquer une disposition de données du système de fichiers, puis le système de stockage de destination crée un système de fichiers clone du système de fichiers d'après les premières informations. Après que le système de stockage de destination a créé le système de fichiers clone correspondant au système de fichiers dans le système de stockage source, une application sur le système de fichiers dans le système de stockage source s'exécute, et peut également s'exécuter sur le système de fichiers clone. Du fait que la création du système de fichiers clone ne nécessite qu'une disposition de données d'un système de fichiers source, c'est-à-dire qu'il n'est pas nécessaire de transmettre des données d'un fichier compris dans le système de fichiers, et qu'un volume de données de la disposition de données est petit comparé au volume de données des données comprises dans le fichier, il en résulte une réduction d'un retard temporel dans un processus de migration d'applications.
