Design And Implementation Of Network Data Backup And Recovery System

Along with E-business and the electronic government affairs of computer system and network equipment application deepen continuously, artificial wrong operating, the defect of system software or application software and destroyed hardware, computer virus and hacker attack, unnormal electricity and destroyed machine accidentally , many factors such as natural disaster that have the possible damage that causes the crucial data in computer ( such as WEB page, Email, operating system and database etc. ) with lose. Above-mentioned fault belongs to systematic logic fault. Logic fault is not easy to discover, but it can be resumed as long as having original data. It needs to backup historical data for a long period. Therefore possessing the fine "Data Protection System" and "Data Protection Scheme" can fall to the minimum level with the loss of disaster. We can preserve data information fairly completely through backuping. when occuring systematic unexpected terminal accident because of data problem, we can let backuped data to normal in the best times through resuming system , guaranteeing that system offers service promptly and continuously . Backup and recovery operation of crucial data have become an importand part of systematic daily operation maintenance. When occuring systematic unexpected terminal accident because of data problem, we can let backuped data to normal in the best times through resuming system, guaranteeing that system offers service promptly and continuously. Backup and recovery operation of crucial data have become an importand part of systematic daily operation maintenance. Furthermore, the higher enterprise and different department need electronic degree, the deeper they rely on computer system and network as well as the higher they need backup, scale and technology. As a kind of storage and management work, backup and recovery data are concerned with different business demand in different enterprise and department (data bulk, storage structure, management cost, etc ).Also there are many technical difficulties which need more strong technical support and service. But initiative, practicality, integrity and economy of backup work is the common goal of storage and management work. According to this present situation, we need to offer different solution scheme and establish storage strategy through server, storage device and correlative software, etc that fulfill the backup of data and recovery of system that can be used by application field and usage object. The system that we design is to face the all type data adopt drive technology to unify handling, carrying out multiple position backup of real time, resuming it when the data of data source encounters damagement, which has reduced the expense, at the same time also raised efficiency of backup and recovery. The backup and recovery system, developed by us, that is based on network data source copy way, can guarantee the complete consistency of source server and backup server, Enterprise and government sector can adopt our backup software, alos using original ways ,and realize the timing backup and the real-time backup. Network data backup and recovery system apply to extensively popular personal computer and PC server. User can set many data catalogs on source server to be crucial business data, keep watching on the crucial business data by software and store these datas on the buffer, dispatch to the goal backup system of host-computer, from the goal backup land of main computer of real time or timing( the goal backup host-computer reserves updating logs, in the time of designated user for data updating ) land update on the goal disk . Concentration-management has offered systematic state and the disposition maintenance for entire system to keep watch on function, has realized a no-typed data does not have the automatic backup of type difference, with recovery the unified, centralized management of function, and need not serve end for every backup and recovery to differentiate management. It offers two parts to user:concentrati...
