Abstract
본 발명의 목적은 교환기 백업 기능의 본래목적인 데이터와 디스크의 데이터 일치성을 보장하고 실시간 시스템의 성능을 만족하면서 로그데이터의 손실에도 불구하고 백업 가능한 클라이언트-서버(Client-Server) 구조를 갖는 백업 방법을 제공하는데 있다. 이러한 본 발명은, 첫째, 로그의 손상이나 프로세서간 통신 전송을 위한 백업 프로세서의 주소값 상실등 백업 클라이언트-서버(Client-Server)에 의한 백업 불가능의 경우에도 교환기 시스템의 성능을 저하시키지 않고 디스크와 메모리의 데이터 일치성을 유지시켜 항상 정확한 데이터로 교환기를 운용할 수 있도록 높은 신뢰성을 제공한다. 둘째, 교환기 운용상 최빈 시간을 이용한 메모리 데이터 덤프를 전담하는 오딧 클라이언트-서버(Client-Server) 시스템의 운용으로 신속하고 정확한 데이터 백업 방법을 교환기 시스템에 제공함으로써 교환기 시스템의 성능을 크게 향상시킬 수 있다.An object of the present invention is a backup method having a client-server structure capable of backing up in spite of the loss of log data while ensuring the data consistency of the original data of the exchange backup function and the disk and satisfying the performance of the real-time system. To provide. First, the present invention provides the disk and the disk without degrading the performance of the exchange system even when the backup is not possible by the backup client-server such as log corruption or loss of the address value of the backup processor for interprocessor communication transmission. It maintains data consistency in memory, providing high reliability so that the exchange can be operated with accurate data at all times. Second, by operating the Audit Client-Server system dedicated to the memory data dump using the least time in the exchange operation, the performance of the exchange system can be greatly improved by providing the exchange system with a quick and accurate data backup method. .
