Abstract

L'invention concerne un procédé et un appareil de récupération de système. Le procédé comprend : la réception d'une demande de modification (S110) ; et, si la demande de modification demande une modification sur un fichier d'un répertoire prédéfini, l'envoi de la demande de modification à un lecteur de disque dans lequel le fichier du répertoire prédéfini est situé, pour effectuer la récupération (S120). Par le biais de la reconnaissance d'un fichier d'un répertoire prédéfini, une demande de modification visant le fichier du répertoire prédéfini est envoyée directement à un lecteur de disque correspondant au fichier du répertoire prédéfini, de sorte qu'une opération d'écriture différée est évitée, et qu'on peut être sûr que d'autres fichiers n'ayant pas besoin de récupération sont conservés dans le disque.
