As you can see in our
compatibility page the latest version available for Joomla! 2.5 is indeed Akeeba Backup 4.1.2. We
have dropped support for Joomla! 2.5 in January. This is in line with our long standing policy of supporting Joomla! releases up to one month after they are officially declared end-of-life.
I would recommend that you should update your site to Joomla! 3 as soon as possible, regardless of our software. Joomla! 2.5 is end of life for 9 months, therefore
insecure to use. Some of the security fixes in recent Joomla! releases do affect Joomla! 2.5 as well but nobody is going to provide a patch. Being left with an old site like that is a major risk, only in part mitigated by the use of Admin Tools or any other security product (no security software can protect you from all 0-day exploits).
