Abstract

Дублиращата програма за компютърна система с харддиск поддържа запис на измененията, направени в данните във файла, който е бил дублиран. В продължение на дублирането и двете части на файла, оригиналните и актуализираните, или записите са запаметении дублиращата програма чете оригиналните данни, докато другите приложения четат актуализираните. Зада идентифицира дали една операция четене е инициирана от дублиращата програма или от друго приложение, използвайки стека системата определя източника на задаване на четенето. Алтернативно, тя запитва ползувателя, процеса или задачата. Достъп до файла чрез дублиращата програма е гарантиран чрез манипулиране на System File Table. Чрез забавяне стартирането на дублиращата операция за определен период се осигурява файлът да е в "добро" състояние.
