Usenet is my backup. I've tried to make Backblaze my backup a couple times but the ETA on completing the first pass is always right about never.
It's interesting to think that, as flash densities surpass hard disks, it'll become cheaper to store data on flash than on spinning metal once you factor in rack space and power consumption.
Won't take that long.
I love all the Backblaze drive update posts about the lifespans of storage media.
