CrashPlan has my data, won't give it back

I remember setting up a pair of NASes for a customer, units I hadn't used before. I found that the configuration restore did not work at all and the two built-in backup tools a) would only allow a full restore of any backed-up folder and b) were unconscionably fragile, respectively.

Luckily this was blatant in testing and as the rest of the units' functions worked nicely, I decided not to send them back, and rolled my own backup. Which is tested, and has much better alerting/monitoring.

For the rest I got my NAS, and I live with the fact that if the house burns down well then that data goes out the window.

Just because you can back up everything in the cloud doesn't mean you should.
