Apple used to have a fantastic application called OSX Server (now called MacOS Server) which allowed you to run a full server from any OSX computer. A server can allow you share files, run your own email or web server, remotely connect in to your office etc. OSX server was particularly powerful running on a Mac Mini. With OSX Mojave Apple killed off OSX server, but it is still possible to download an older version from Apple that still works. Here’s how.
Here’s how to get the FTP server running in OSX 10.9 Mavericks. This is advanced and not everyone will need the FTP server. The only thing I was use it for is to receive incoming scans from my Fuji/Xerox network scanner.
This will backup your entire remote server to your local Macintosh computer. It uses the command line so it’s not for beginners.
