Abstract
With the rapid development of information technology, the application of database in network environment is increasingly extensive, and the threat of network failure to database system is becoming more and more serious. Studying effective backup and recovery strategy has become the key to ensure data security. This study aims to optimize the database backup and recovery strategy to deal with the network failure, based on the existing theory and technology, and propose a dynamic adjustment mechanism integrating multi-factor considerations. We build the simulated network fault environment and test the performance of the traditional fixed cycle backup strategy and the proposed dynamic adjustment strategy. The results show that the new strategy can significantly reduce the storage cost and improve the recovery efficiency under the premise of ensuring the data integrity. The innovation point is the introduction of the network condition assessment model, which makes the backup timing more intelligent and reasonable, and the development of a technical solution combining incremental backup and differential backup to reduce unnecessary data redundancy.
