We’ll also explore how to restore databases and specific tables, and provide tips for beginners and advanced users alike.

Understanding mysqldump

mysqldump is a command-line tool that generates SQL dump files containing the database structure (schema) and data. These dump files can be used to restore the database to its original state or to create a new database with the same structure and data.

Backup a Single Database

To back up a single MySQL database, use the following command:


mysqldump -u [username] -p [database_name] > [backup_file.sql]

Replace [username] with your MySQL username, [database_name] with the name of the database you want to back up, and [backup_file.sql] with the name of the file to which you want to save the backup.

Backup Multiple Databases

To back up multiple databases, specify them in the mysqldump command as shown below:


mysqldump -u [username] -p --databases [database_name1] [database_name2] > [backup_file.sql]

List the databases you want to back up after the --databases flag, separated by spaces.

Backup All Databases

To back up all MySQL databases on your server, use this command:


mysqldump -u [username] -p --all-databases > [backup_file.sql]

This command backs up every database on the MySQL server to a single SQL file.

Backup Database Structure Only

To back up just the structure (schema) of a database without the data, use:

The --no-data flag ensures that only the database structure is backed up, excluding the data.

Backup a Specific Table

If you need to back up a specific table within a database, use this command:


mysqldump -u [username] -p [database_name] [table_name] > [backup_file.sql]

Replace [table_name] with the name of the table you wish to back up.

Backup Database Data Only

To back up only the data without the structure, run:


mysqldump -u [username] -p --no-create-info [database_name] > [backup_file.sql]

class=”img-responsive”
The --no-create-info flag excludes the table creation statements from the backup.

Restore a MySQL Database

To restore a MySQL database from a backup file, use the following command:


mysql -u [username] -p [database_name] < [backup_file.sql]

Ensure the database exists before restoring it. You can create the database with this command:


mysql -u [username] -p -e "CREATE DATABASE [database_name];"

Restore a Specific Table in the Database

To restore a specific table from a backup file, ensure the backup file contains only the data for that table and use:


mysql -u [username] -p [database_name] < [backup_file.sql]
