In a nutshell, Akeeba Backup Core is an open-source backup component for the Joomla! CMS, quite a bit different than its competition. Its mission is simple: create a site backup that can be restored on any Joomla!-capable server. Its possibilities: endless. It 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. If you want a reliable, easy to use, open source backup solution for your Joomla! site, try it out.
