Problems solved by technology

Using these traditional backup methods, once the amount of data surges, it will take a long time to back up or restore the entire database or table, and the efficiency of the entire user system is very low.
In a word, the existing database backup methods have the following deficiencies: 1. The backup tool provided by the database itself should be used for backup; 2. The backup data is difficult to identify, and it is difficult to carry out secondary development on the backup data; Part of the data is backed up; 4. The backup data cannot be restored to a different database
5. Affect user system efficiency

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] figure 1 It is a schematic diagram of the system structure for database backup. Such as figure 1 As shown, a monitoring and backup module is defined between the database DB and the user system, and the monitoring and backup module is responsible for implementing the database backup method proposed by the present invention. In the monitoring and backup module, there is a database interface, which is responsible for constructing the statement connecting with the database; the backup content template, receiving the definition of the application system, and forming a database query statement; the file storage template, forming the storage method of the backup file. The monitoring and backup module receives the definition and control from the user system, and completes the backup of the database.

Abstract

The data base back-up method includes the following steps: setting monitoring and back-up information; analyzing the content in data base; connecting data base; performing back-up content inquiry while starting back-up; and back-up of the inquiry result. In the said method, the key business information in data base may be backed up timely in unattended mode. The method provides flexible template customizing mode to back up partial information in data base at user's will. In addition, recognizable binary file back up mode is adopted to makes it possible for the user to off-line browse the backed up data for further analysis and secondary development as well as guiding the backed result to other data base to complete operation between different data bases.

Description

technical field [0001] The invention relates to a method for operating a database, in particular to a method for backing up a database. Background technique [0002] General large-scale user software systems need to store, back up and analyze the collected key business information. These business information are usually very important and have a huge amount of data. In the prior art, for the backup of key business information in the database, the backup tool provided by the database itself is mostly used for backup. Such as Veritas' Backup Exec backup and recovery products, ORACLE's export and import tools. Using these tools for backup cannot back up part of the data in the database table. In addition, the storage and organization of the backed up data are also different from ordinary files. It is difficult for users to directly view the files or do secondary operations on them. develop. If the user wants to view the backup data, he must use the recovery tool of the data...
