The Archiving group The-Eye did actually made a back up of the Archive torrents. https://the-eye.eu/public/Random/archive.org_dumps/torrents/ They have a text file listing the file list of all the collexted torrents. It’s a text file. That they had to compress. And it’s still around 800Mo big just for that one.
What do you suggest ? Jpeg-xl ? Avif ?
