Embodiment Construction

[0045] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0046] see Figure 3 to Figure 7 , this embodiment provides a method for backing up a database and a method for restoring a database. Among them, the database runs on the database host, and the user can access the database running on the database host through the client terminal. The database in the database host is backed up on the back-end platform, and the backup data on the back-end platform can be restored when there is a problem with the database host. to the database host. Preferably, the database can be an ORACLE database, which has the characteristics of good portability, convenient use, and strong functions, and is suitable for various large, medium, small, and microcomputer environments. ORACLE database is a relational da...

Abstract

The invention relates to the technical field of databases, and provides a database backup method, a database restoration method and a storage medium. The database backup method comprises the followingsteps: carrying out full backup on a database; performing periodic incremental backup on the database; and periodically synthesizing more than two times of incremental backups into a full backup to obtain a new full backup. The database restoration method comprises the following steps: directly mounting a memory of the back-end platform on a database access terminal; constructing a database operation environment on the database access terminal; and enabling the database access terminal to directly access the database from the memory of the back-end platform. According to the method, the backup data volume of the database can be greatly reduced, the database restoration time is shortened, and the access time of database failure or restoration is prolonged.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database backup method, a restoration method and a storage medium. Background technique [0002] With the widespread use of database technology and the continuous increase of user data volume, database data backup and restoration has become an important factor in evaluating database security and efficiency. [0003] In the prior art, the backup methods of data in the database include full backup and incremental backup, wherein the full backup refers to backing up all the data in the database from the beginning to the end; and the central idea of ​​the incremental backup is to reduce the amount of data to be backed up. You don't need to start the backup from scratch anymore, you only need to back up the data blocks since the last backup. Regarding incremental backup, there are different levels such as 0, 1, 2, 3, and 4. Among them, level 0 is the highest level, and level 4 is...
