I don't get this. The local-only backup option is already encrypted. Why can't they include an option for me to upload it somewhere of my choosing, like Google Drive, or even using Android's built-in backup system, so I can do it for free (my current backup file is well over a GB)? I already donate $5/mo to Signal Foundation; building a paid-only backup solution gives me a bad taste.
I even wrote a small Android app to do GDrive uploads of the encrypted backup file, watching the local backup directory for new files. (It broke with an Android version update and I haven't gotten around to fixing it.)
