Can you elaborate on the concept of EPICSHELTER as explained in Permanent Record?

EPICSHELTER, as explained in the book 'Permanent Record', is a comprehensive backup and disaster recovery system developed for the National Security Agency (NSA). The system was designed to restore all the data collected by the NSA back to normal, even in the event of a major disaster at Fort Meade, the NSA's headquarters. This means that EPICSHELTER was essentially a fail-safe, ensuring the NSA's data could be recovered and operations could continue even in the face of significant disruptions.

Question was asked on:

Snowden took up a new contract job with the NSA in Japan, as a Dell employee on paper. This center was responsible for maintaining the NSA infrastructure across the Pacific and spying on most countries in that region. The NSA was far more advanced than the CIA in terms of Cyber-intelligence. However, it lacked the most elementary security features, including encryption and global backups. Snowden was tasked with building EPICSHELTER, a comprehensive backup and disaster recovery system for the entire NSA. EPICSHELTER could restore all the data collected back to normal, even if Fort Meade went down.
