Abstract

Selon l'invention, une mémoire inactive est synchronisée avec une mémoire active dans un système informatique insensible aux défaillances comprenant un processeur actif. Des données sont copiées de la mémoire active à la mémoire inactive par un traitement en tâche de fond qui permet au processeur actif d'effectuer des opérations normales pendant l'exécution de l'opération de copie. Une fois l'opération de copie terminée, une détermination est établie pour savoir si les données provenant des zones de la mémoire active dans lesquelles des changements ont été opérés peuvent être copiées dans la mémoire inactive dans un laps de temps préétabli, au moyen d'un traitement prioritaire qui empêche le processeur actif d'effectuer des opérations normales. Si les données peuvent être copiées dans la mémoire inactive par traitement prioritaire dans ledit laps de temps préétabli, l'opération est effectuée et la copie, la recherche et la détermination sont répétées pour les zones de la mémoire active dans lesquelles des changements ont été opérés.
