How to download the entire github?

Question

Backup

There are various Wikipedia dumps (for example, the English section weighs under 40 GB compressed (pictures) and 90 GB full) and other large useful sites.
So, do you know who have github dumps with all repositories? Or can you tell me how to make it and how much it can approximately weigh?

Answer 1

There is a "GitHub Archive Program" initiative, here you can read about different archiving methods:
https://archiveprogram.github.com/
In July 2020, a 21 TB archive of the site for February was placed in the repository. The data is stored on 186 reels of 1 kilometer long film, coded as separate, dense reels (each containing 120 GB of QR code data.

On February 2, 2020, we took a snapshot of all active public repositories on GitHub to archive in the vault. Over the last several months, our archive partners Piql, wrote 21TB of repository data to 186 reels of piqlFilm (digital photosensitive archival film). Our original plan was for our team to fly to Norway and personally escort the world's open source code to the Arctic, but as the world continues to endure a global pandemic, we had to adjust our plans. We stayed in close contact with our partners, waiting for the time when it was safe for them to travel to Svalbard. We're happy to report that the code was successfully deposited in the Arctic Code Vault on July 8, 2020.
