I known they are more than enough of them already floating around the internet, but hey, I figured I'd share it here anyway.&lt;/p&gt;
+&lt;h2&gt;The script&lt;/h2&gt;
+&lt;p&gt;For the script to work, you'll need to edit a few variable to match your configuration.&lt;/p&gt;
+&lt;ul&gt;
+&lt;li&gt;&lt;code&gt;BACKUPDIR&lt;/code&gt; is the path of the directory where you want your backups to be stored.&lt;/li&gt;
+&lt;li&gt;&lt;code&gt;BACKUPUSR&lt;/code&gt; is the user that will connect to MySQL to dump the databases. It should have access to all you databases without needing a password.&lt;/li&gt;
+&lt;li&gt;&lt;code&gt;EXCLUDELIST&lt;/code&gt; is a list of databases that should not be backed-up. Leaving it as is is probably fine.&lt;/li&gt;
+&lt;/ul&gt;
+&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;span class="ch"&gt;#!/bin/bash&lt;/span&gt;
+
+&lt;span class="nv"&gt;BACKUPDIR&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;/home/user/backup&amp;quot;&lt;/span&gt;
+&lt;span class="nv"&gt;BACKUPUSR&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;user&amp;quot;&lt;/span&gt;
+&lt;span class="nv"&gt;EXCLUDELIST&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;^Databases&lt;/span&gt;$&lt;span class="s2"&gt;|^information_schema&lt;/span&gt;$&lt;span class="s2"&gt;|^mysql&lt;/span&gt;$&lt;span class="s2"&gt;|^performance_schema&lt;/span&gt;$&lt;span class="s2"&gt;&amp;quot;&lt;/span&gt;

+&lt;span class="o"&gt;}&lt;/span&gt;
+
+&lt;span class="o"&gt;[[&lt;/span&gt; -e /usr/bin/mysql &lt;span class="o"&gt;]]&lt;/span&gt; &lt;span class="o"&gt;&amp;amp;&amp;amp;&lt;/span&gt; sqlbk
+&lt;/pre&gt;&lt;/div&gt;
+
+
+&lt;p&gt;I personnaly have this script running once a week, in my user's personnal crontab (editable using the &lt;code&gt;crontab -e&lt;/code&gt; command) :&lt;/p&gt;
+&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;## WEEKLY DATABASE BACKUP
+@weekly /home/user/bin/backupdb
+&lt;/pre&gt;&lt;/div&gt;
+
+
+&lt;h1&gt;Conclusion&lt;/h1&gt;
+&lt;p&gt;You've probably noticed that the script erases the previous backup when a new one is made.&lt;/p&gt;
+&lt;p&gt;I don't need to keep multiple versions of the same database backup on my servers because they are all saved remotely on a daily basis using &lt;a href="http://rsnapshot.org/"&gt;Rsnapshot&lt;/a&gt;. I'll probably write an article on the subject in the future.&lt;/p&gt;

 &lt;p&gt;However, every time I've wanted to add a domain, create a new mailbox or change a user's password, I've had to do it manually from a SQL shell. As fun as it may be, it does get old very fast, so I've decided to install a web frontend to manage this database.&lt;/p&gt;
 &lt;p&gt;After a bit a googling, I've settled on &lt;a href="http://postfixadmin.sourceforge.net/"&gt;Postfix Admin&lt;/a&gt;.&lt;/p&gt;
 &lt;p&gt;The latest stable version of Postfix Admin was released in 2009. Version 3.0 has been in the works for some time now and the project can be cloned from their &lt;a href="https://github.com/postfixadmin/postfixadmin"&gt;Github repo&lt;/a&gt;.&lt;/p&gt;
