1、With the Shaanxi Expressway networking toll, toll extension business is now weighing charges for storage charges database security and backup of business data has become more prominent. After two years of operation, more and more awareness of the operating units to database stability issues is a pro
2、blem not to be ignored. Simple examples such as: failure of the servers and databases, general maintenance and management staff, in many cases, cannot be independent and quick recovery, had an impact on production. So we need a proper data backup solutions. Database is the core of the whole system,
3、database security should pay more attention. Therefore, the formulation of appropriate database backup strategy, is to maintain database security norms as well as the guidelines, to backup the data it needs from the technical, as well as administratively regulated. In data security, data security st
4、rategy is to maintain the integrity, confidentiality and availability of information. Therefore, database security policy will focus on these three points, including physical security, access control, data backup and emergency response. Here, in the toll collection system in the province uses the SQ

Shaanxi Provincial Expressway networking toll began in May 2004, as of now there are more than 200 data server, as more sections of grid-connected charges, charges data as the core of the whole system, it is necessary to establish
7、a set of data security and reliable solution. 2 purpose this time through the analysis of network data in server health, Shaanxi Provincial Expressway networking toll system based on data, statistical methods of data storage, data research, original charge as possible security, integrity and privacy

For the opening section after incorporation fees provide a reliable set of data security policies. 3 database security situation in the province Shaanxi Provincial Expressway networking toll system overview 3.1 database-tier systems, management systems, branch-level management system, the

So when a database server fails, you do not need to pass data to recover, simply through the collection procedure for charging water data collection to complete the fast recovery of server failures. 4.4 analysis summary summary analysis, lane because it is not a complete s

15、防泵房土方开挖方案need to select the real-time synchronization method of the programme. Typically backup system comes with backup solutions should be preferred. If the system comes with a backup plan if it cannot meet the requirements, software development methods is needed. Or third-party software systems a
16、re selected for backup. Because third-party backup software is usually priced very high, charging units require high price, so for only the first two methods are studied below. 5.1 use MS SQL2000 synchronized backups of SQL 2000 database in three ways, namely snapshot replication, transactional replication and merge replication. By comparison, excluding the first two programmes, select synchronization transactional replication and database Nothwind database, for
