The 2b2t server has a data footprint that exceeds 80 TB. Storing the entire 2b2t server would demand at least eight 8TB M.2 SSDs or, as an alternative, five 16TB SATA SSDs. As such, the team engineered a custom file compression format specifically for this project, named .zvcr (Zstd-compressed Version Controlled Regions). Common Minecraft servers use the .mca (Minecraft Anvil) file format, which is fine for single-player worlds or even small servers. Unlike the .mca file format, which normally uses Zlib or Gzip compression, .zvcr uses the Zstd (Zstandard) algorithm that yields higher compression ratios.
