How to backup sql database files

Sqlserver database backup several ways

In the actual database Sqlserver operation and maintenance process, many times we need to do the data backup operation, you can do a regular backup, you can also do manual database backup. The following is a detailed description of these backup methods.

(1) database backup

This method of backup database is the most complete, you can backup all the objects in the database to generate a . The operation of backup in this method is directly in the Sqlserver database management software, select the database, right-click and select Tasks, and then select Backup, as shown below

Then enter the backup interface, select the path where the backup will be stored and set the backup file name, and then click OK to perform the backup, as shown below

(2) Generate scripts for single-table backup

Sometimes our business system can be backed up by a single table, and if there is a problem, we can restore the database directly through the .bak file.

Sometimes the update of our business system may involve only one table or several tables, at this time you can operate through a single table backup for each data table, only the backup of these data tables involved in the change operation. The method of operation is to select the database in the Sqlserver database management software, right-click and select Tasks, and then select Generate Script, refer to the first figure in Method 1. Then enter the Generate Script interface, select Next to enter the Settings interface:

After entering the Settings interface, select a specific database object, and then select the data table you need to back up from it, as follows:

And then click Next to enter the Storage Path and Export Settings interface, Save to File can be selected to save as a single file or a file for each object. The key point here is to remember to select the Advanced button, set the data type of the script to be written in it, otherwise the default rules exported to the file contains only the table architecture statements (i.e., the SQL statement to create the table), does not contain any table data. As shown below

Select the Advanced button and go to Advanced Settings, scroll down to the end of the drop-down menu to see a setting called Type of data to script. Set this to either Architecture and Data or Data Only. Only the files exported in these two ways contain data from the table, and the architecture-only export is just the statement that creates the table.

After setting the above information and clicking Finish, the backup file is automatically created to the specified storage path, and the generated file is a database SQL file with a .sql extension.

(3) Quickly back up a table to a temporary new table with the SelectInto statement.

This backup method is to quickly write the found data into the specified new table of backup and create the table automatically.

For example, if you quickly back up all the data of the Proct table in the A database to the Proct_0228 table in the ABackUp database, you can use the following statement to operate, which can be executed directly in the New Query window.

Select*IntoABackUp.dbo.Proct_0228FROMA.dbo.Proct;

Executing this statement requires that the table behind the into does not exist prior to the execution of the existence of the above statement can not be executed. The Proct_0228 table does not need to be processed manually, the above statement automatically creates a structure consistent with the Proct table when it is executed.
