Abstract
A centralized backup system for a non-local homogeneous real-time system comprises a switch (302), and a host (301), an encryptor (303), a PC monitor (304), and a firewall (305) which connect with the switch. The centralized backup system ensures the reliability of the non-local systems and is able to allocate resources flexibly to meet the requirement of the tasks of system in each different location by centralized deployment and centralized management of backup systems in all locations.
