摘要
针对传统的数据库备份,数据库的备份与源数据库的结构特征紧密相关,备份中心存储资源严重浪费的现状,提出了一种与数据库结构无关的数据库备份的存储方法。通过数据封装、多级索引等技术在备份中心实现数据库备份数据的存放形式与源数据库的数据结构无关,实现了不同种类数据库的备份数据共享一个存储平台。实验结果表明,该方法不仅能实现不同种类数据库共享存储,而且有效地提高了系统资源的使用效率。
Due to database backup largely depended on the structure of source database in traditional database backup and recovery system, the resource of backup center is extremely wasted. According to the problem, a database backup storage method is presented. Through encapsulating data and multilevel index, the method implements the separation of logic structure of data and specific physical storage. The method supports different kinds of database backup data share a storage space. The experiment proved that the method not only implements different kinds of database share storage, but also improve the efficiency of system resources.
