Cloning a database means creating an exact copy of an existing database, typically to run tests or for backup purposes. Both MySQL and MariaDB, while being separate database systems, originated from the same codebase and offer similar functionalities. This similarity extends to the process of cloning databases as well.
Many developers and administrators rely on database cloning for various reasons, from development testing to backup strategies. Regardless of the motivation, having a reliable and efficient cloning process is crucial for these systems.
With MySQL and MariaDB, you can use simple command-line utilities or structured query language (SQL) statements. This guide will cover how to clone a database using both the command line and SQL-based methods.
$ mysql -u root -p - Enter password:
You need the appropriate privileges to access both the source and destination databases.
$ mysqldump -u root -p source_database > source_database.sql Enter password:
mysql> CREATE DATABASE destination_database;
$ mysql -u root -p destination_database < source_database.sql Enter password:
This step will clone all data and structures from the source to the destination database.
$ mysql -u root -p Enter password: mysql> USE destination_database; mysql> SHOW TABLES;
This will list all tables in the destination database. Cross-check them against the source database to ensure completeness of cloning.
$ rm source_database.sql
Always make sure you have backup copies of important data before deleting any files.
Your database should now be successfully cloned from the source to the destination. Regularly backup your databases and consider automating the cloning process if it's a recurring task for you.
