<h1>Backup and Restore MySQL/MariaDB Databases</h1>
<div id="preamble">
<div class="sectionbody">
<div class="paragraph">
<p>As you use XAMPP, you might find that you need to backup or restore a MySQL or MariaDB database. There are two easy ways to do this with XAMPP: using the browser-based phpMyAdmin tool or using MySQL/MariaDB’s command-line tools. This guide describes both options.</p>
</div>
<div class="paragraph">
<p>This guide assumes that you already have a PHP application that uses a MySQL/MariaDB database deployed on XAMPP. The example application used in this guide is WordPress, although the steps outlined below will work for any application.</p>

<div class="sectionbody">
<div class="paragraph">
<p>XAMPP includes <a href="http://www.phpmyadmin.net/">phpMyAdmin</a>, an open-source, browser-based tool for managing MySQL/MariaDB database servers. To backup a MySQL/MariaDB database using phpMyAdmin, follow these steps:</p>
</div>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>Browse to <a href="http://localhost/phpMyAdmin" class="bare">http://localhost/phpMyAdmin</a> or <a href="http://127.0.0.1/phpMyAdmin" class="bare">http://127.0.0.1/phpMyAdmin</a>. If required, log in using your database access credentials. On a fresh XAMPP installation without any changes, you can log in as <em>root</em> with a blank password.</p>
</li>
<li>
<p>Select the database to be backed up from the list in the left navigation pane. In this case, we’re backing up the WordPress database, which is named <em>bitnami_wordpress</em>.</p>

<div class="content">

</div>
</div>
</li>
<li>
<p>Select the "Export" command in the top navigation bar.</p>
</li>
<li>
<p>On the resulting page, select "Quick" as the export method and "SQL" as the output format. Click "Go" to proceed.</p>

</div>
</li>
</ol>
</div>
<div class="paragraph">
<p>phpMyAdmin will export the database to a text file as a series of SQL statements. Once done, the browser will prompt you to download it to the desktop. This text file is your backup, so store it safely!</p>

<p>At a later point, you may wish to restore the database. To restore the data to a fresh MySQL/MariaDB database using phpMyAdmin, follow these steps:</p>

<li>
<p>Browse to <a href="http://localhost/phpMyAdmin" class="bare">http://localhost/phpMyAdmin</a> or <a href="http://127.0.0.1/phpMyAdmin" class="bare">http://127.0.0.1/phpMyAdmin</a>. If required, log in using your database access credentials.</p>

</div>
</li>
<li>
<p>Select the new database from the left navigation pane. In the resulting page, select the "Import" command in the top navigation bar.</p>
</li>
<li>
<p>Click the "Browse…​" button and select the backup file created earlier. Click "Go" to proceed.</p>

<p>You should now update your application’s configuration and point it to your newly-created database. For example, with the Bitnami WordPress module, you will need to edit the <em>wp-config.php</em> file in the <em>apps\wordpress\htdocs\</em> subdirectory of your XAMPP installation directory. Within this file, you will need to update the <em>DB_NAME</em> constant to use the new database name.</p>

<td class="content">
By default, PHP (and therefore phpMyAdmin) is configured to only accept uploads up to 128 MB in size. If your database is larger than this, you need to modify the PHP configuration file to accept a larger upload size. To do this, edit the <em>php.ini</em> file in the <em>etc\</em> subdirectory of your XAMPP installation directory and increase the values of the <em>post_max_size</em> and <em>upload_max_filesize</em> variables. Save your changes and restart Apache for the changes to take effect.

<p>MySQL and MariaDB include two command-line tools that you can use to quickly backup and restore databases. The <em>mysqldump</em> tool is used to export the contents of a database to a text file, while the <em>mysql</em> client can be used to import data from a text file into a MySQL/MariaDB database.</p>
</div>
<div class="paragraph">
<p>To backup a MySQL/MariaDB database from the command line, follow these steps:</p>

<div class="olist arabic">

<p>Ensure that the MySQL/MariaDB server is running.</p>
</li>
<li>
<p>Open a new Linux terminal.</p>

<p>Use the command below to export the contents of the selected database. In this example, we’re backing up the WordPress database, which is named <em>bitnami_wordpress</em>, to a file named <em>bitnami_wordpress.sql</em>. This text file is your backup, so store it safely!</p>
