How does the Death Star get all that data?

When you’re in the IT business, you experience a wide range of occupational hazards. You can’t go to a mall, for example, without wondering how the wireless infrastructure is set up. Do they have locationing and know exactly where I am, including the dressing room or cheating on my diet at Mrs. Fields?
When I saw the latest installment of the Star Wars series, “The Force Awakens”, I did what I always do when I see a sci-fi movie. I tried to figure out how far we are from actually having all those cool gadgets.
Or, as The Joker said in “Batman”, “Where does he get those wonderful toys?”

More than that, I wondered how the Death Star was able to power all that data streaming.

Let’s do some basic math here.
1. The Death Star had an estimated population of 1.7 million humans and 400,000 droids (yeah, I looked it up; don’t mock me).
According to a Digital Universe study, by the year 2020, the entire population of Earth will create a total of 40 zetabytes of data per year, or 5.200GB per person.
That means the 1.7 million people on the Death Star would use 8.84 exabytes every year.
Yes, we know lots of these storm troopers will be demolished by the Resistance, but let’s stick with this basic number. And, realistically, with all the extra gadgetry (think smartwatch x 10¹⁰⁰⁰), the futuristic people would grind through data like a Wookie at a buffet).
2. Now, let’s look at the droid-based data.
Consider each of the 400,000 droids like the Internet of Things in the galaxy far, far away. Every droid is certainly stirring up more data than your smartphone. With their humanoid complexity, I calculated they would create the same amount of data demand as the living, breathing beings.
Multiplying 5,200 MB times 400,000, I get a total of 2.08 exabytes per year.
Let’s also remember that the Death Star is a battleship.
It is heavily armed with lasers.
What’s the on-board GPS system like that it enables them to aim these lasers with pinpoint precision? Certainly, the locationing is light years beyond our own. Plus, they’re not just focusing on Earth, but all those other civilizations in other galaxies.
3. Finally, where are they storing all the backup?
Is there some other cloud out there? Where are they hiding it? Certainly not on a vulnerable satellite. Have they found a way to maximize the potential of the stars in the galaxy?
I could never be a screenwriter, because I would be far too obsessed with these details!
