Abstract

Les modes de réalisation de l'invention fournissent un système de sauvegarde de données, une carte de commande principale et un procédé de sauvegarde des données et appartiennent au domaine technique des communications. Le système comporte une carte de commande principale primaire. La carte de commande principale comporte un module de sauvegarde de surveillance. Le procédé consiste à surveiller le bus de données de la carte de commande principale primaire, conformément à l'adresse de données surveillée; à déterminer si les données correspondant à l'adresse de données doivent être sauvegardées; dans l'affirmative, à envoyer les données correspondant à l'adresse de données à une carte de commande principale de secours pour sauvegarde. Dans les modes de réalisation de l'invention, un module de sauvegarde de surveillance est ajouté de façon synchrone à la carte de commande principale primaire et à la carte de commande principale de secours. La sauvegarde de données entre la carte de commande principale primaire et la carte de commande principale de secours est effectuée par les modules de sauvegarde de surveillance. La charge de travail de l'unité centrale est donc allégée et les possibilités unitaires du système de communication améliorées.
