If you want to automate your backups, please consult our Akeeba Backup User's Guide for up-to-date information on doing that. We offer a wide array of options to do that, complete with step-by-step instructions. Even the free, Akeeba Backup Core, version can be automated using CRON jobs which make use of the front-end backup feature.
Akeeba Backup User's Guide can be found under the Documentation section of our web site.
It's a discontinued plugin. If you still have it on your site: uninstall it and don't use it.
