Abstract

L'invention concerne un procédé et un appareil de stockage de fichiers, un dispositif et un support. Le procédé consiste à : en réponse à une demande de stockage pour un fichier cible, acquérir des informations de modification sur un fichier d'origine, le fichier cible étant un fichier obtenu par modification du fichier d'origine, et un fichier de stockage du fichier d'origine comprenant au moins un fichier de données et des données d'index cibles correspondant audit fichier de données (310) ; déterminer des données nouvellement écrites sur la base des informations de modification, les données nouvellement écrites comprenant au moins des données d'index cibles mises à jour (320) ; et remplacer les données d'index cibles par les données nouvellement écrites, de façon à obtenir un fichier de stockage du fichier cible (330). Le procédé peut améliorer l'efficacité de stockage d'un fichier cible.
