1. MySQL Backup (Exporting Data)

MySQL provides the mysqldump command to create backups.

Command to Backup a Database:

mysqldump -u root -p database_name > backup.sql

mysqldump → Utility for exporting database data.
-u root -p → Specifies the database user (root) and asks for a password.
database_name > backup.sql → Saves the backup in a .sql file.

2. MySQL Restore (Importing Data)

To restore a database from a backup file, use the mysql command.

Command to Restore a Database:

mysql -u root -p database_name < backup.sql

mysql → MySQL command-line tool.
database_name < backup.sql → Restores data from backup.sql to database_name.

3. Key Benefits of Backup and Restore

Prevents data loss in case of system failures.
Helps in database migration from one server to another.
Ensures recovery from accidental deletions or corruptions.

Conclusion

Regular backups are crucial for data security and disaster recovery. Using MySQL’s mysqldump and mysql commands, you can efficiently backup and restore databases, ensuring business continuity.
