<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 class="imageblock">

</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>

<p>On the resulting page, enter a name for the new database (in this case, <em>myblog</em>). Select the collation "utf8_general_ci". Click "Create" to create the database.</p>

</div>
</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>phpMyAdmin will import the data from the backup file. Once complete, you will see a screen indicating the status of the import.</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 2 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>php\</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">

<li>
<p>Launch a new Windows command shell using the "Shell" button in the XAMPP control panel.</p>
