Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0021] 1. Data backup

[0022] Figure 1 shows the implementation process of data backup.

[0023] The input items of the data backup process are the library table name list files on the computer hard disk and the record data in the database; the output items are the backup results given in the form of files, and the files record all the database tables to be backed up in multiple Insert statements. record information. When restoring data, you only need to execute these Insert statements in the output item to restore the backed up data to the database.

[0024] Step 1, read the library table name stored in the library table name list file on the computer hard disk in order in the input item, generate the Delete statement part of the data backup file, put it into the first memory 1, and this part is used when restoring data , first delete ...

Abstract

A method for backup and restoring important data includes such steps as choosing the database lists to be backup and restored, storing the database list sequence in the form of configuration file on hard disk, searching the data in relative database list from relational database to generate backup data, storing in the mode of text file on hard disk, and restoring the data by writing the relative data from text file to database. Its advantage is high speed.

Description

technical field [0001] The invention provides a method for backing up and restoring important data, and particularly relates to a component and method for backing up and restoring important data in a system using a relational database system for data storage. Background technique [0002] For any large and medium-sized software system, data backup and recovery are the most common and basic functional requirements. The existing practice is to use the tools provided by the database management system (DBMS, such as SQL Server, Oracle, etc.) to implement. However, they all have disadvantages such as poor flexibility, unfriendly user interface, and complicated operation to varying degrees. [0003] Take Microsoft SQL Server as an example. In the first edition of "SQL Server 7 Relational Database System Management Guide" published by Machinery Industry Press in April 2000, it provides three backup methods: [0004] Full backup - backs up all database ob...
