so I have a home server set up that nobody in my house wants to use. I was going to set it up to be a file server/backup kind of thing but apparently everyone would rather just use up of gigs of storage on their devices instead. I want to use it as more than a backup server. I've heard of using home servers for media, downloading files, and backups. what could I use it for besides that stuff? it's an Ubuntu server running on virtualbox.
