Good luck getting them to a) admit they have it and b) send you a copy ;)

As a taxpayer, aren't I entitled to a restore? :-)

I know you're joking but to stay on topic, you still have to even get them to even admit they have your data, since it's supposedly illegal. Thanks to Snowden we know, but even in light of those leaks, they have and will probably continue to lie during Senate/Congressional hearings. Once we get past that hurdle, then we can talk about restoring your illegally captured data ;)

File an FOIA request.

It’d definitely take longer to process than Backblaze FedEx-ing you a HDD ;)
