How much data the NSA really gets

Fear not, says the NSA , we “touch” only 1.6% of daily internet  traffic. If, as they say, the net carries 1,826 petabytes of information per day, then the NSA  “touches” about 29 petabytes a day. They don’t say what “touch” means. Ingest? Store? Analyze?
For context, Google in 2010 said it had indexed  only 0.004% of the data on the net. So, by inference from the percentages, does that mean that the NSA is equal to 400 Googles?
Seven petabytes of photos are added  to Facebook each month. That’s .23 petabytes per day. So that means the NSA is 126 Facebooks.
Keep in mind that most of the data passing on the net is not email  or web pages. It’s media. According  to Sandvine data (pdf)  for the US fixed net from 2013, real-time entertainment accounted for 62% of net traffic, P2P file-sharing for 10.5%.
