Design And Implementation Of Data Backup And Recovery System Of Sichuan Provincial Electric Power Company Technical Skills Training Center

As information Service Corporation of all kinds of business developed, thecompany in dealing with daily business at the time of information application systemincreasingly.Each application system carrying business data is an important resourcefor companies, which can promote the normal business operation. Thus the internalcomputer data is a very important resource. But in some cases, such as vandalism,computer virus, software and hardware failure data has been lost, so there will be a greatloss. We must find an effective and reasonable method for data protection.The application of information technology has developed rapidly, critical dataquantity of data to data security problems grew, the various sectors on the internet torely on less obtrusive on to the network to provide more opportunities and data backupsto restore is necessary, and the backup system is a maintain security and usability of themost important tool.Data backup as an information system which is the most importantcomponent of security, it has also been made more and more attention. the network andthe rapid development of education has made it more convenient to carry and use data,but human error, the hard disk damage, the computer viruses, electricity and otherreasons may cause data loss, so to look important data backup.This paper introduces the first to resume the relevant knowledge and technical,then introduced the national and international data backups to restore the status quo, thedata backups to restore the meaning of technology and methods used by customizing thehook with the rules for the computer file systems of real-time data monitored to ensuredata integrity, the mainstream encryption algorithms and to provide the custom of theinterface and data security, based on the implementation of the socket of the data file oftransport and transit reliable. Network load small; finally, using the vc plus plus6.0design and implement a backup and data based on a host of the software, the tool forevery increment of the two backing up and data compression (winrar support theformat), the backup and data recovery purposes. through the test and analysis, thesystem stable, reliable, there is value in use.Through the implementation of the program,good to the company of each application system on-line automatic data backup and data storage centralized hierarchical management objectives, reduce or even eliminate the insome accidental reasons caused by the loss of data may, in the reliability of data securitybased on the upgrade, not only can improve the system the work efficiency, and thecorresponding to meet business development and expansion of the system requirements.
