Data Security and Reliability Solutions
First,background description
The Internet technology and its application greatly promoted the Chinese enterprises and organization of information technology popularization, information system of enterprise and internal organization has taken shape, including employees of PC, the server to the data center. The use of information system has greatly improved the operation efficiency of enterprises and organizations, and effectively reduced management costs. But with is in the process of informationization, a large number of office documents, design documents, electronic mail, data table is stored in a computer system, and these data to maintain the whole enterprise operation, once the important data is corrupted or lost, will have a great impact on the day-to-day operation of enterprises, it is difficult or even make up for the loss.
Second, the main reasons for data destruction in enterprise network system environment are as follows:
1）natural disasters cause storage data to be destroyed or completely lost.
2）computer equipment failure, including storage medium aging, failure.
3）data corruption caused by viral infection.
4）hacking on the Internet and vandalism from intranets.
5）MIS operation of system administrators and maintenance personnel.
Third, solutions
The reasons for the loss of these data, we may say we can through some other way to look back to the data, such as virus damage, we can use anti-virus software in the system will clear the virus and so on. Facts show that authoritative research data show that, in most cases, the data are irreversible. For example, the virus will be completely destroyed in the server implementation programs and files, even if the smooth clearance of the virus, also can make the application back to normal; the software failure data consistency is destroyed, in no case can not return to the backup before complete state. And the reliability of computer network system needs complete data storage system to solve.
Backup system has reliable recovery ability, can provide a comprehensive security system, from production data, data backup and backup management system should have the safety guarantee system of high reliability, data security. Therefore, it is very important for the original network to increase data storage, backup and disaster recovery system, and to include data storage backup disaster recovery system in the new network scheme.
Stage backup: backup data will be divided into two stages, the recent backup data stored in the disk medium, near line backup; access frequency is not high but still has to preserve the historical data value stored in the backup tape media, offline backup.
Remote disaster tolerance: you can periodically store backup data on tape devices, and then take out the tape medium,transportation to remote computer room storage, to achieve data remote disaster tolerance.
Protect legacy assets: you can use both love number backup, storage cabinets, leading disk backup schemes to protect data, and double protection using tape media to protect legacy assets of existing investments.
