Abstract

La présente invention concerne un procédé de mise à jour et de retour en arrière des données d'un dispositif terminal. Le procédé comprend la sauvegarde des données devant être mises à jour avant que le dispositif terminal effectue l'opération de mise à jour de manière à résoudre le problème dans l'état antérieur de la technique d'une consommation importante de ressources de serveur et de réseau et permet également d'éviter le problème d'une transmission de données aisément défectueuse. Avec le procédé de la présente invention, il n'est pas nécessaire de transmettre les données de sauvegarde pendant le retour en arrière, ce qui permet d'économiser des ressources de réseau et de réduire la quantité de données transmises par le réseau. Si des utilisateurs découvrent des erreurs après la mise à jour, ils peuvent retrouver les données de sauvegarde et effectuer le retour en arrière par eux-mêmes. Et si des opérateurs trouvent des erreurs après la mise à jour, ils peuvent envoyer une requête de retour en arrière depuis le serveur au dispositif terminal et effectuer le retour en arrière des données.
