Percona XtraBackup is a free MySQL-based software that allows you to create hot backups. It’s also free and open-source. You can make hot backups of running MySQL, MariaDB, or Percona Server databases with Percona XtraBackup without stopping the database service or rendering it read-only. For many online companies, this is an important function.
In this post, I’ll show you how to install and use Percona XtraBackup on a Vultr server running the One-Click WordPress application to perform complete and incremental hot backups. We’ll take a complete backup and two incremental backups before restoring the database to the state of each of the three backups.

The basic SQL (Standard Query Language) interface language of the MySQL database allows for inserts, modifications, and queries of data stored in relational tables. The SQL language is also used to manage the database, including the development and modification of tables, users, and permissions.
Database privileges (such as Select priv, Insert priv, and so on) are specified in the “db” mysql table. The mysql “user” table may delegate the same privileges (Select priv, Insert priv, and so on), but global privileges (which normally default to ‘N’).
We’ll need the current password for the root user to log into MySQL and secure it. If you’ve just installed MySQL and haven’t yet set the root password, the password will be blank, so simply type it in.
An anonymous user is provided by default in a MySQL installation, allowing anyone to log into MySQL without having to build a user account. This is only for testing purposes and to make the installation go more smoothly. Before going into a production setting, you can get rid of them.
