Pick a VPS from a hosting provider outside of your home country (Brazil in this case). Use it to hold encrypted backups. Either a Syncthing instance configured as untrusted, or just btrfs send incremental snapshots and filter the stream through gpg on the way out.

I suppose your other issue is making sure that payments still get made in a timely manner if for some reason your home country freezes your assets or you get arrested. I guess it just depends on what you're up to and how paranoid you are. Personally I wouldn't worry about it too much. You could probably just deposit a portable hard drive with a friend or relative periodically if you're that concerned.
