Yes, some articles I read suggested this would be organizational so I tried to have some hope.
Now I feel if only root will survive, it would be enough. I could recreate everything from it.
And you are right. I should have some "emergency plans". I was never plan to run it this way long term (I expected to stop being dependent on this in 2020 or 2021, didn't expect it for 10+ years really, but it turns I have to wait not sure how long) but it happened and I have to treat this seriously.
These are people who I personally know and have contact with so if needed I could inform them about changes. If someone download this without my knowledge I couldn't control it more than publishing messages some time before something would change.
