Sheltered Harbour: banks are putting their data in a safe place - why?

This post is more of a question than a proper article: are banks setting up a system to keep their data in a safe place for when the system implodes? Do they know something we don't? Are they getting ready for the currency reset as foretold in the 1988 Economist?

"In a world where attacks on computers are nearly de rigueur at this point, it isn’t much of a surprise that U.S. banks have begun quietly doomsday-prepping for a successful apocalyptic attack on their computers by hackers. The goal is to head off a run on the bank by panicked citizens."

"Called Sheltered Harbor, the project currently includes banks and credit unions holding between them about 400 million U.S. accounts. The project requires that each member bank offers up its data such that it can be used by other firms in the event their computers are totally disabled by a cyberattack." Source: pymnts.com

The Financial Services Information Sharing and Analysis Center (FS-ISAC) announced an industry-led, nonprofit initiative designed to extend the financial industry’s capabilities to securely store and rapidly reconstitute customer account data should the need arise.

I don't believe for a moment that they are doing this just because of potential hackers. I have a lot more questions, but I'll just post this as it is for now.
