Embodiment Construction

[0026] refer together figure 1 and figure 2 , the embodiment of the data incremental backup method of the present invention comprises:

[0027] Step 101: preprocessing, customizing the data table to be backed up, directly filling in the table name of the data table in the business data table file, and indicating whether the data of the business table is added or updated;

[0028] Step 102: Incremental backup, that is, after customizing the required backup data table, connect to the database to be backed up, perform stored procedure analysis according to the custom-defined data table, and finally generate directly executable data for inserting and updating Structured query language SQL script statement set;

[0029] Step 103: making a recovery file, that is, packaging the generated set of SQL script statements to obtain a data recovery file.

[0030] The above-mentioned embodiment provides an easy-to-implement database incremental recovery and backup idea through a series o...

Abstract

The invention discloses data incremental backup method and system. The method comprises the following steps of: defining a data table to be backed up, directly filling a table name of the data table in a service data table file and indicating whether the data of the service table is added or updated; connecting a backup database after the data table to be backed up is well defined, analyzing the storage process according to the well-defined data table and finally generating an SQL (Structured Query Language) script statement set which can be directly executed and used for inserting updating; and packaging the generated SQL script statement set to acquire a data recovery file. The invention can realize high-efficiency and flexible data incremental backup.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a data incremental backup method and system. Background technique [0002] Digital information management is an important technical force in the information age, and databases are widely used in society to store enterprise information data. Traditional database backup and recovery generally use the full backup, differential backup, log backup and other backup modes provided by the database itself. [0003] However, the existing database backup is difficult to realize incremental backup of data or selective backup of business data, and it is difficult to realize efficient data backup and recovery. [0004] Chinese Invention Patent Application No. 200710201769.X published on March 25, 2009 discloses a backup system and method for shrinking image files. The method includes the following steps: [0005] Obtain the name of the drawing to be backed up and the drawing database of ...
