I use rclone, which is essentially rsync for cloud services. It supports encrypion out of the box.
I use https://mycorrhiza.wiki/ it is not very fancy but it is a single executable file and stores pages in a git repository, so no database is needed and doing the export is as simple as reading some files.
Yes, you are right, I already use DNS validation. But it is just it is easier to request a single wildcard certificate for my domain and have all the subdomains that I use for the local services defined only in my local DNS. I cannot fully automate the certificate renewal because namecheap requires to allowlist the IP that can call its API, and my ip is dynamic. So renewing a single certificate saves me time. Also, the wildcard certificate is installed on a single machine, so it is not the I increase a lot the attack surface by not having different certificates for each virtual host.
I’ve used https://www.bestheating.ie/btu-calculator to decide the power of my new boiler, so far it is working well. But as other said, this is likely a very rough approximation.
https://shadowsocks.org/ should be a good option, easy to install, encrypted, and password protected
For a simple dynamic DNS, I have been using https://www.duckdns.org/ for a few years and been happy so far
The main storage is a Nas that is mounted in read only most of the time and has two drives in raid mirror. Plus rclone to push a remote and client side encrypted backup to backblaze.
