Just used the non-commercial version of Akeeba Backup along with the extractor Kickstart and was able to backup my existing site and restore it in a different location where I will be upgrading it and testing the upgrade apart from the live site. It all went smoothly and I was very pleased with the process. Thanks for a very helpful extension! Would highly recommend it. When the upgraded site is complete I will be installing Akeeba there for regular backups.
