Overview
In this tutorial, we will learn about MySQL Database Backup. MySQL offers various methods for
backup the database and its data. It is important to back up the MySQL database. Unfortunate events like system crash can cause damage and database tables can be lost. If a serious system crash occurs, we want to be able to restore the tables to the state they were in at the time of the system crash with as little data loss as possible.
Database backups are also useful for copying databases from one MySQL server to another database
server. This is also useful in database testing. We might want to test a server for a new release and
want to use it with some real data from the production server, or to load the data into
external applications.
To ensure the best results during backup and restore database::
- Verify and test the database backup and restore procedure
- We need to perform backups at regular intervals of time
- Use a consistent and meaningful naming scheme for the MySQL backup files
- Clean the older backup files periodically to keep them from filling the hard disk
Database Export
SQL statements can be used to invoke the necessary backup files. Also, there are MySQL client programs that assist in the export/import process. We can export the database and tables using the following methods:
- Using utility like mysqldump
- Using an SQL query
Export with mysqldump utility
