Abstract

The present invention discloses a centralized backup system for a non-local homogeneous real-time system, comprising a switch (302), and a host (301), an encryptor (303), a PC monitor (304), and a firewall (305) which connect with the switch. The present invention 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 location different greatly with each other by centralized deployment and centralized management of backup systems in all locations.

Claims

1. A centralized backup system for non-local homogeneous real-time systems, characterized by comprising a switch, and a host and a firewall connected with the switch;

the host comprising a server, an optic fiber switch and a disk array, wherein

the server is used for controlling the reproduction of the data of the non-local systems, ensures the synchronization between the reproduced data and the parent data in the non-local systems, and replaces a non-local system when the non-local system encounters failure;

the disk array stores the reproduced data; and

the firewall performs network switching when switching from the non-local system to the backup system.

2. The centralized backup system for non-local homogeneous real-time systems of claim 1, wherein the server comprises a plurality of logic servers, each having its own databases on the disk array.

3. The centralized backup system for non-local homogeneous real-time systems of claim 2, wherein the logic server includes a data reproduction server and an application server.

4. The centralized backup system for non-local homogeneous real-time systems of claim 1, further comprising an encryptor.

5. The centralized backup system for non-local homogeneous real-time systems of claim 1, further comprising a PC monitor.

6. A centralized backup method for non-local homogeneous real-time systems, characterized by comprising a switching step when a non-local system encounters failure and a restoring step when the failure is eliminated, wherein

the switching step comprises:

disconnecting the network of the non-local system;

switching application and the network; and

starting a centralized backup system;

the restoring step comprises;

restoring the network of the non-local system;

switching to restore the application and the network; and

starting the non-local system, wherein

the centralized backup system comprises a switch, and a host and a firewall connected with the switch, the host comprising a server, an optic fiber switch and a disk array;

wherein the server is used for controlling the reproduction of the data of the non-local systems and ensures the synchronization between the reproduced data and the parent data in the non-local systems, and replaces a non-local system when the non-local system encounters failure;

the disk array stores the reproduced data; and

the firewall performs network switching when switching from the non-local system to the backup system, and wherein the server comprises a plurality of logic servers, each having its own databases on the disk array, and the logic servers include a data reproduction server and an application server.

7. The centralized backup method for non-local homogeneous real-time systems of claim 6, wherein the step of switching the application and network comprises:

importing the reproduction of the data of the failed non-local system to the application server from the data reproduction server;

starting the application server; and

on the firewall, mapping the IP address of the application server as the IP address of the non-local system to the network.

8. A non-local homogeneous real-time system, characterized by comprising a centralized backup system, a plurality of non-local systems, and a network, wherein

the centralized backup system comprises a switch, and a host and a firewall connected with the switch, the host comprising a server, an optic fiber switch and a disk array, wherein the server controls the reproduction of the data of the non-local systems, ensures the synchronization between the reproduced data and the parent data in the non-local systems, and replaces a non-local system when the non-local system encounters failure;

the disk array stores the reproduced data;

the firewall is used for network switching when switching from the non-local system to the backup system;

the centralized backup system is connected to the network through the firewall; and

the plurality of the non-local system are connected to the network.

9. The non-local homogeneous real-time system of claim 8, wherein the server comprises a plurality of logic servers, each having its own databases on the disk array.

10. The non-local homogeneous real-time system of claim 9, wherein the logic server includes a data reproduction server and an application server.
