How else do you backup your servers to your NAS without it being networked?

In future, be sure to thoroughly read my replies -of which my post below answers your question.

Apart from businesses who rely on remote connections to access and transfer data

Because nothing is bulletproof and the internet is a scary place if you don't know what you're doing.

Which further supports my view on the matter:

I cannot fathom why any home user would risk their sensitive data by connecting their device online.

I'm just not afraid because I know how to secure network-facing devices like a NAS, or whatever. Anyway these days I mostly use it for Plex and remote editing. The rest of it is for storage and redundant backups for, as mentioned, web server content and VM's. I asked specifically why you don't think you can do this. If you trust yourself and you can secure it then no problem. Otherwise, sure, if it's questionably setup then I wouldn't recommend doing anything like remote NAS. Keep it local if you're not sure. I use mine a lot for work stuff and I often need to access my things from other places, so I've made sure to research everything I need to be 100% sure.
