Ai Faner’s previous article mentioned, global data storage will soon show “insufficient storage space” As a warning, people began to pursue ultra-high storage density and eternal storage time. The “glass disc” in the Microsoft Project Silica project has been used for thousands of years.
This is only part of Microsoft’s data storage program. GitHub, the software source code hosting service platform acquired by Microsoft last year, recently announced a code archiving program Arctic Code Vault, bury the open source software codeUnder the hundreds of meters in the Arctic, it will be kept for at least 1000 years.
I’ve covered it in the previous article, but the longest lifespan of available storage media is only about 60 years. The emerging storage media like “glass disc” and DNA storage are still a long way from mature commercials, then GitHub What storage device should I use to archive the code for thousands of years?

The answer is film. GitHub uses a film coated with iron oxide powder on the surface of the Norwegian company Piql AS. It is said that this film can be stored for 750 years under normal conditions, if it is cold and dry. The low oxygen cave can be stored for 2000 years.
From February 2nd, 2020, GitHub took snapshots of all public repositories, processed and stored in QR code (QR code) on a roll of 3,500 feet (1066.8 meters) long film. It is then stored in an abandoned mine in Svalbard, Norway.
The Svalbard Islands are located between the Norwegian mainland and the North Pole. They are called “the northernmost city in the world”. The cold environment is conducive to extending the storage life of the film. Moreover, according to the Svalbard Treaty, this area is a permanent non-military area, which means that data corruption will not be lost due to war and other reasons.
