Legacy local backup
The normal backup allows us to save our backup both in a remote FTP server and locally.
You should definitely enable this for Legacy backups as well! Support department told me that we have to request it in order to be added. Spread this out, because I own a Joomla website with phpbb forum, the database, files, mysql, are way too huge (backup over 20GB) and they can only be saved with Legacy backup. So my backup is not saved locally.
