Sure! I’ve had a cheap VPS on digitalocean for a few years, mainly just to host a few web pages for friends / family. Just found their guide to getting synching running you can pretty much follow for any server you’re running.

So tldr; I get a sync directory that’s always going to be the same on a Linux laptop, a Mac desktop, an Android phone, etc. It’s amazingly useful- and yes, I’m aware of the irony that DO is technically a cloud service (you could always take this to the next level and run a physical server on your own)
