Mozy Hypothesis and the End of The World

The times they are a-changin’.

This post seems to be older than 17 years—a long time on the internet. It might be outdated.

Mozy is an online backup utility that I’ve been using for a few months now. I wrote about it on StudentTabletPC a while back:


You get 2GB for free! This is perhaps the biggest selling point. One of the other online backup sites I was looking at,, only offers 1GB. With Mozy, I get twice as for the same low cost (of free).

It’s easy to setup. Selecting files is a two part processes. First you select types of files to backup: documents, settings, bookmarks, financial, etc. Then you can select folders to backup as well.

It’s secure. This for me is a huge deal. Mozy uses 448-bit BlowFish encryption with my own private key. This means that unless you have my super secret password, you better count on spending the next few millennia trying to get access to my data.

Backs up open and locked files. I have Mozy set to backup around 4am every morning. Basically, I just leave my Tablet on and it does the rest. But what if I forget to close a document? Some backup programs would freak out and not backup the document I have open. But not Mozy, it will backup the file even if Windows has a lock on it.

Bandwidth Throttle. Not a huge deal for me, but still worth mentioning. You can set maximum uploads limits on Mozy so it doens’t suck all your bandwidth when it’s sending your files to their server. I do this at 4am, so it’s a non-issue for me.

One other thing worth mentioning is that you don’t have to perform an entire backup session at once. For example, let’s say that I have Mozy set to backup files X, Y, and Z. Mozy starts running at 4am just like I told it to. It backs up file X and starts to backup file Y, but then my Internet stops working because I have a crappy ISP.

No problem. When my Internet comes back, Mozy will pick back right where it left off.

It’s been about three months since I started using Mozy and thus far it’s been excellent. I would consider it the most successful, most complete, and most reliable system I have ever used and recommend it to everyone I know who’s looking for a backup service. In short, I’m very happy with it.

There is however, something cool about Mozy that I didn’t know. Every time Mozy backups my files, it also disproves the Riemann Hypothesis.
This is actually rather interesting since the Riemann hypothesis is probably the single greatest mathematical question of our time. It’s proof (or disproof as the case may be) would have catastrophic impacts on society.

Why? In short, almost all current cryptographic methods exploit a calculation efficiency with prime numbers. That is, the processing power to calculate the product of two very large prime numbers is exponentially ridiculously small versus the processing power needed to take the product and break it back down into the original prime numbers. Proof of the Riemann Hypothesis would create a quick way to break the product of two primes down and thus obliterate secure transactions. The point being, proving the Riemann Hypothesis more or less would be the end of the world…at least for the time being.

Of course, Mozy is really disproving the Riemann hypothesis. It’s an joke from the Mozy programmers. I sent them a “har har” message:

To the programs who have too much fun at Mozy,

Disproving the Riemann hypothesis on my computer, eh?

Thanks for a good laugh and keep up the good work!
