Akeeba Backup Core is the most widely used open-source backup component for the Joomla! CMS. Its mission is simple: create a site backup that can be restored on any Joomla!-capable server, making it ideal not only for backups but also for site transfers or even deploying sites to your clients' servers. Akeeba Backup creates a full backup of your site in a single archive. The archive contains all the files, a database snapshot and an installer similar in function to the standard Joomla! installer. The backup and restore process is AJAX powered to avoid server timeouts, even with huge sites. Alternatively, you can make a backup of only your database, or only your files. Akeeba Backup is the reliable, easy to use, open source backup solution for your Joomla! site.
ENJOY!
