The related characteristics of database backup, including the physical backup, the logical backup, the static backup and the dynamic backup, were firstly analyzed in this paper. Besides, key factors of database disaster tolerance were reviewed from the viewpoint of database backup. Then, this paper mainly discussed database disaster tolerance technology based on OS (operation system) and storage, and illustrated the working principal, structural features and specific applications through structural diagrams. Research results provide useful reference for the theory and practice of the database disaster tolerance technology.
