The U.S. Government Accountability Office (GAO) has audited the use of computer image and hard disk technologies, for the purpose of archiving all government documents, and concluded computer technical stuff does not sufficiently protect the government's data.
In the case of a massive brownout, global printer virus, terrorist act, generators out of gas, or other disaster, the risk that all information will be unattainable is too great.
The GAO has therefore concluded that disaster planning will include the archiving of hard copy documents for all government business.
The GAO estimates that in the event of a disaster where electricity isn't available it would cost ten billion man-years or six hundred trillion dollars to recreate piles of documents, electronic or hard copy. And that requires waiting until everything is recreated.
The GAO has recommended, for greater economy and efficiency in public expenditures, that the less expensive option is to photo copy everything and place multiple copies in strategic underground facilities throughout the US.
The GAO estimates that in the event of a disaster where electricity isn't available but hard copies are would have up front costs of three billion man-years or one hundred trillion dollars. After the disaster the government could immediately access photocopies of the piles of documents, electronic or hard copy.
