Data Backup & Restore For MySQL (Command-Line)

MySQL is a popular open-source relational database management system. It is important to create regular backups of MySQL databases to protect against data loss due to hardware failures, software bugs, or other issues. In this answer, I will explain how to backup and restore a MySQL database using the command-line interface.

Backup using mysqldump:

The mysqldump command is used to create backups of MySQL databases. Here are the steps to backup a MySQL database using mysqldump:Open the command-line interface (e.g., Terminal on Mac or Linux, Command Prompt on Windows).Type the following command to create a backup of the database:

                       "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 backup, and "backup_file.sql" with the name of the file you want to save the backup to.Enter your MySQL password when prompted.

The above command creates a backup file in SQL format that contains all the data and structure of the specified database.

Restore using mysql:

To restore a MySQL database from a backup file, use the mysql command. Here are the steps to restore a MySQL database using the mysql command:Open the command-line interface.Type the following command to restore the database:

                  "mysql -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 restore, and "backup_file.sql" with the name of the backup file.Enter your MySQL password when prompted.The above command restores the database from the backup file.

               

 Following some steps to choose specific path you store entire data with specific       database with backup and restore: 

Note : If the database already exists, the above command will overwrite the existing data with the data  from the backup file. If you want to create a new database from the backup file, you can use the  following command:

                                     "mysql -u username -p < backup_file.sql".

This command will create a new database with the same name as the database in the backup file, and import the data and structure from the backup file.

In conclusion, using the mysqldump and mysql commands is a simple and effective way to backup and restore MySQL databases. By regularly creating backups and storing them in a safe place, you can protect your valuable data from potential loss or corruption.
