Research And Implementation Of The Backup Server's Key Technologies

In the past 20 years, with the rapid development of the computer technology, people rely on the computer also growing. If the user's substantial data which is stored in the computer is lost, the loss is immeasurable. Data disaster become increasingly important.Network backup system's goal is to provide a data backup and recovery solution which is in network environment. The system has tripartite structure. It is composed by backup server, backup agent and storage server. Three parts are installed and run independently. Backup server lead the system's operation logically, deal with user's orders, control task's running and send the result . In addition to the above three parts, the system also includes a console which send commands and receive information.For improving the system's performance, it use parallel mode to schedule backup jobs. By the multi-user's order processing technology, it makes the system to accept the multi-user's order parallel. By the multi-access mode technology, it makes users to visit the system by B-S or C-S mode. By jobs or network's monitor technology, it makes system to monitor the job's process and the network connection between the tripartite structure.When the network backup system's tripartite structure is single backup server,single backup agent, single storage server; single backup server,single backup agent, more storage servers; single backup server,more backup agents, single storage server; single backup server,more backup agents, more storage servers, the system can complete parallel backup tasks very well. The system support for multi-user access, and monitor the job's operating in and network connectivity when it's in the process.
