Abstract
With the rapid development of information technology, the application of databases has become increasingly widespread across various fields, making data security and reliability focal points of concern. To address the risk of data loss, this study focuses on optimizing database backup and recovery strategies to enhance data protection efficiency while reducing costs. Through an in-depth analysis of existing backup and recovery technologies, it was found that traditional strategies suffer from issues such as resource wastage and excessively long recovery times. Consequently, a dynamic backup strategy based on an intelligent prediction model is proposed, which incorporates machine learning algorithms to predict data access patterns, thereby enabling on-demand backups. Additionally, a distributed storage architecture is introduced to enhance data redundancy and availability, and a multi-level recovery mechanism is designed to shorten the average recovery time. Experimental results demonstrate that this optimized solution can reduce backup frequency by 30% and decrease recovery time by 45%, significantly improving overall system performance. Furthermore, by constructing a cost-benefit evaluation model, the economic advantages of the new strategy are validated. This research not only provides an innovative solution for database management but also offers theoretical references for related fields such as cloud computing and big data processing, possessing significant academic value and practical application significance.
