I'm going to take on board everything that has been said, completely restructure the system and bring it into play in a couple of weeks.
Thanks to everyone for bringing these things to my attention.
The reason the size was so small is servers that I've hosted beforehand for other people, years ago, weren't using that much space.
The servers are based in a French datacenter, Im a volunteer at a local radio station and one of the main technicians own them.
I'm going to lock this topic now, start building in a more secure system and go through everything.
Thanks again!
