"Since world wide harddrive storage being created is about 40 exabytes per year and the Internet has about 50 exabytes of traffic per month, I would still say you're crazy to think that all traffic is recorded."
I'm not claiming that they record everything, but want to point out that half of the 50 exabytes are generated by Netflix and youtube. IOW, no need to store it, or at least not store it more than once.
Also, it should be safe to assume that lots of internet traffic is redundant (web sites serving the same page over and over again), so
a neat combination of compression and a hash file system should reduce storage requirements quite a lot.
