While I used to run it on my main server, I’ve moved it to a Raspberry Pi that stays powered on 24/7. That way, even if the main server is off for maintenance, file syncing continues uninterrupted.

Options like Raspberry Pi OS, Ubuntu, or specialized server distributions open the door to multiple applications designed to secure your files.

Last month saw the introduction of the Zero Terminal 3 modular handheld computer powered by a Raspberry Pi Zero. And last year NODE designed the Mini Server V2 with a Raspberry Pi 3 at its heart.

The launch site for the Raspberry Pi 4 Model B is mostly running on a cluster of 18 of the little devices themselves. Fourteen handle PHP code execution, two serve static files, and two run memcached.
