You gotta make money somehow. Maybe have an optional durable+accessible storage and portal (just a SaaS and optional harddrive that you ship out or update on occasion... a miniPC that pulls from the SaaS using rsync automatically?).

You might be able to make this work if you sell enough of the SaaS subscriptions (12 bucks a month or 200 a year for perrenial backups -- ship us the device/etc. and we'll get the media into your account. You'd need 1000 customers with a 20% systems cost to do this full time, which seems reasonable).
