Regardless of how you host Nextcloud, what you described is one thing I really like about Nextcloud: the major part of it being synced to several devices. As long as you have a computer with the desktop client that’s on every once in a while, your stuff is saved across different devices.
I’ve had a similar thing happen once btw, deleted the wrong server. It was “just” monitoring data, but I had spent a lot of effort building it properly. I eventually started over it, but knowing the whole thing is gone feels really bad.
Cool, ungefähr zu der Zeit bin ich von vegetarisch zu vegan geswitched, und ehrlich gesagt weiß ich nicht, ob ich das auch gemacht hätte, wenn’s nicht plötzlich so viel veganes Zeug überall gegeben hätte.
