What is EPIC SHELTER? Why did Edward Snowden design EPIC SHELTER? How did it give him an insight into NSA systems?<\/p>\n\n\n\n

Designed by Edward Snowden, EPIC SHELTER is a backup program used by the NSA. Using EPIC SHELTER, files that aren’t already backed up are sent to servers at NSA headquarters.<\/p>\n\n\n\n

After Geneva, Ed took a new job in Japan in 2009. He went back to being a contractor (for Perot Systems, which was acquired by Dell) and worked for the NSA. Initially, his job was to connect the CIA<\/a> and NSA\u2019s infrastructure so they could share data.
<\/p>\n\n\n\n

EPIC SHELTER<\/strong>: Snowden Fixes NSA Backup Problem<\/h4>\n\n\n\n

One of the problems the NSA faced in Japan was how to back up data. Ideally, local NSA facilities would send copies of their data back to headquarters at Fort Meade. However, sending data takes up a lot of bandwidth, so people weren\u2019t doing it. As a result, if anything happened to the local server, the information was gone forever. 
<\/p>\n\n\n\n

Ed was assigned to solving this problem. He was to build a storage and backup system that was automatic and constantly updated. The system was code-named EPIC SHELTER. Snowden faced challenges with the project.
<\/p>\n\n\n\n

For Edward Snowden, EPIC SHELTER was a hard project for several reasons, the main one being duplicated data. The NSA had tons of computers, many of which had the same files on them. Sending a hundred copies of the same file to NSA headquarters was a waste of bandwidth and storage space.
<\/p>\n\n\n\n

Ed built a deduplication system that compared files on all NSA computers. If,<\/em> and only if, <\/em>a file on a local computer didn\u2019t already exist at headquarters, the system would send it to headquarters to be backed up. This cut down on the number of files that needed to be sent, saving bandwidth.
<\/p>\n\n\n\n

Suspicion of Mass Surveillance Programs<\/strong><\/h4>\n\n\n\n

During his time working in Japan on EPIC SHELTER, Snowden was also exposed to some things that made him suspicious about possible mass surveillance. He attended a conference on China. The technology briefer canceled at the last minute and one of the chiefs asked Ed to step in. The topic was how much China could monitor US agents working in China. As Ed read about what China was doing, he came to the conclusion that the US must have done some of the same things to their own citizens.<\/strong> If mass surveillance was possible, and the US already had the information about how to do it, there was no way they wouldn\u2019t have tried it themselves, he reasoned. However, while China was spying on its citizens publicly, if the US was doing it, it was in secret. 
<\/p>\n\n\n\n

Ed tried not to dwell on his suspicions. He rationalized them by comparing US views on freedom to China\u2019s. China has an authoritarian government and the Great Firewall keeps citizens in and everyone else out. In contrast, the US government is democratic and doesn\u2019t control Internet content or who can access it. At the time, Ed thought the US government only interfered with the Internet for defensive, targeted purposes.
