TL;DR
A group of dedicated players has completed the largest Minecraft world archive, totaling 15 TB, from the 2b2t server. This effort involved over a year of data collection using automated bots, preserving the server’s digital history for public access.
A team of Minecraft enthusiasts has unveiled the largest publicly available world archive in Minecraft history, totaling 15 TB of data from the 2b2t server. This achievement involves a comprehensive preservation project that used automated bots to capture over a year of server data, making it it available for download and analysis. The project aims to preserve the digital history of the infamous anarchy server, which has been active since 2010.
The project was carried out by the 2b2t.place team, which employed 28 bot accounts to continuously fly around the server map, downloading and storing all world data sent by the server. The archive includes a 1 million by 1 million block area of the Overworld, a 512,000 by 512,000 area of the Overworld from a previous period, as well as significant regions of the End and Nether dimensions. For more details, see the largest available Minecraft world. The entire dataset, highly compressed, amounts to approximately 13.7 TiB of data.
This effort took over a year of development, involving substantial technical challenges, thousands of dollars in costs, and extensive testing. The project was publicly announced via the download link, YouTube videos, and community forums, emphasizing its role in preserving the server’s history amid ongoing changes and potential shutdowns.
Impact of the 15 TB Minecraft Archive
This archive represents the most comprehensive digital record of a Minecraft server ever created, offering researchers, historians, and players a unique window into the server’s history, culture, and evolution. It preserves the chaotic, rule-free environment of 2b2t, which has existed for over a decade, capturing countless player interactions, builds, and server events. The project underscores the importance of digital preservation in gaming communities and provides a resource for future analysis of player behavior, server dynamics, and Minecraft’s development over time.

Background of 2b2t and Data Preservation Efforts
2b2t (short for 2builders2tools) is the oldest active Minecraft anarchy server, founded in December 2010. It is renowned for its no-rules, no-resets environment, resulting in a sprawling, post-apocalyptic landscape filled with player-made constructions, ruins, and exploits. Over the years, the server accumulated over 80 TB of data, with its map continuously expanding. Despite its popularity, much of its history was at risk of being lost due to server updates, map resets, or shutdowns.
Previous efforts to archive parts of 2b2t included partial map downloads and community backups, but none approached the scale or comprehensiveness of this recent project. The current initiative aims to preserve the entire world state, including regions that are no longer accessible or have been altered by players and server updates.
“This was the most complex data collection project we’ve ever undertaken. We wanted to ensure that the history of 2b2t remains accessible for future generations.”

Remaining Questions About the Archive’s Completeness
While the project claims to have captured the largest dataset of 2b2t to date, it is not yet confirmed whether every region, including highly dynamic or corrupted areas, has been fully preserved. The long-term accessibility of the archive also remains uncertain, depending on hosting and community support. Additionally, the exact methods used for compression and potential data loss during compression are still undisclosed.

Future Plans for Data Preservation and Community Engagement
The team plans to continue expanding the archive, including more regions and historical snapshots. They also intend to develop tools for community members to explore and analyze the data, fostering a deeper understanding of 2b2t’s history. Further collaborations with researchers and content creators are expected, and ongoing support via donations and community participation will be crucial for maintaining access.
