No, no, you don't need to add controllers to it. The path is supposed to be like I wrote it. Inside administrator/components/com_akeeba there is a file named backup.php. This is the file you need to run. But, let me stress this, it's in the backend
(administrator) directory, not the front-end. The command is (I hope this time the code tag works):
/usr/bin/php /path/to/your/site/root/administrator/components/com_akeeba/backup.php --profile 1
If the backup.php file is not there, make sure that you have installed Akeeba Backup Professional. If the file is corrupt, please let me know - the new auto-packaging scheme is in experimental format and may have produced a broken archive.
