I assume you basically want protection against disasters, but not high uptime.
(E.g. you likely can live with a week of unavailability if after a week you can recover the data.)
The key is about proper backups. For example, my Nextcloud server is running in a datacenter. Every night I replicate the data to a computer running at home. Every week I run a backup to a USB drive that I keep in a third location. Every month I run a backup to a USB drive on the computer I mentioned at home.
So I could lose two locations and still have my data.
There is much written about backup strategies, for example https://en.wikipedia.org/wiki/3-2-1_backup_rule … Just start with your configuration, think what can go wrong and what would happen, and add redundancy until you are OK with the risks.
I switched to Emacs over two years ago because I was getting too comfortable in VS Code. If VS Code didn’t have the “dodgy” stuff, I would recommend it to everyone without reservation.
Emacs has been a pleasant surprise. The latest versions have introduced Eglot (LSP), EditorConfig and a few other odds and ends that make it very close to being usable with very little configuration. My latest suggestion for getting started is JUST two lines of config, and I think you can scale easily.
I just wish Emacs had started from the outset with more common keybindings- it makes it hard to recommend because you need to make a significant investment. I think it’s worthwhile, but still…
However, due to how it’s evolving lately, I suspect it might become even easier to get started with time. If they rolled in to base Emacs automatic LSP installation, that would be huge, for instance.
