Re: He filled hard disks
I'm not sure that's entirely true, the drives are being moved, so backing them up prior to that would escape any damage caused in transit. Also simultaneously writing to two sets of drives would avoid the fail-on-read problem (and also any fail on write issues, well, not avoid, but do (1-p)^2 on the failure rate). But with this amount of data some of it will be missing or corrupted anyway, so their algorithm for combining it likely has to deal with the missing observations and a corrupt hard-disc in petabytes of data may well just be another source of noise.
