So you’ve acknowledged the same issue, and instead of offering a solution to their issue, you decide to criticize them. They even said they’ve used Arch for 5 years. That’s not a small amount of time to be using an OS. You are what’s wrong with the Linux community, not OP.

Not sure if you’ve de-googled yourself or not but there is a Google Drive Addon that has a whole slew of options for backing up your HA config. I’m sure there are alternate HA add-ons. This may require HACS but not certain.
