Problems solved by technology

Common backups are mainly fixed-period backups in terms of time, but for large changes in the database at any time, there is no flexible backup cycle adjustment; in addition, in terms of database backup methods, no matter whether it is full backup or differential backup, it cannot be based on The importance of different data tables is treated differently, and timely backup of important data tables after changes will easily cause data loss

Embodiment Construction

[0010] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0011] figure 1 Shown is a flow chart of the database backup method provided according to the preferred embodiment of the present invention. Such as figure 1 As shown, the database backup method provided according to the preferred embodiment of the present invention includes steps 101-103.

[0012] Step 101: Obtain a total weighted value according to attributes of tables in the database and corresponding weights, and obtain a priority of the database and a corresponding threshold according to the total weighted value. Among them, the initial priority of the database and the corresponding threshold are preset before the first backup.

[0013] Specifically, multiple data tables in a single database...

Abstract

The invention provides a database backup method and system. The method provided by the invention comprises the following steps that a total weight value is obtained according to the corresponding preset weight and the attributes in a table in a database; the priority of the database and the corresponding threshold value are obtained according to the total weight value; a database variation value is obtained according to different operation types of the database and the corresponding weights. The database variation value and the threshold value corresponding to the database stage are compared, and the backup strategy is executed according to the comparison results.

Description

technical field [0001] The invention belongs to the technical field of databases, in particular to a database backup method and system. Background technique [0002] With the increasing development of social informatization, database technology has been widely used more and more. In daily data transmission applications, database backup is one of the essential operations, and there are various existing backup methods. Common backups are mainly fixed-period backups in terms of time, but for large changes in the database at any time, there is no flexible backup cycle adjustment; in addition, in terms of database backup methods, no matter whether it is full backup or differential backup, it cannot be based on The importance of different data tables is treated differently, and timely backup of important data tables after changes is likely to cause data loss. Contents of the invention [0003] The present invention provides a database backup method and system to solve the abov...
