Yeah fair. I tried setting it up, but honestly probably not worth the effort in home networks. Problem is browsers don’t know that the other end of the unbound DNS server is DoH, so it won’t use ECH. Even once set up, most browsers need to be manually configured to use the local DoH server. Once there’s better OS support and auto config via DDR and/or DNR it’ll be more worth bothering with.

Do you have the local unbound server respond to DoH so that the browser also uses encrypted client hello?

I’ve been using pcloud. They do one time upfront payments for ‘lifetime’ cloud storage. Catch a sale and it’s ~$160/TB. For something long term like backups it seems unbeatable. To the point I sort of don’t expect them to actually last forever, but if they last 2-3 years it’s a decent deal still.

Use rclone to upload my files, honestly not ideal though since it’s meant for file synchronisation not backups. Also they are dog slow. Downloading my 4TBs takes ~10 days.
