Yeah, need to write the program and distributed in r/datahoarder

This should be next on my list since my current project depends on SD model and having data backed up gives me confidence that I can get rid of all their stuff if needed.

Hmm, you can just create a torrent out of it. Either as a single file (impractical, but you can just avoid downloading it fully), or chunk it into multiple files.

You don't even need to store it all at once on your computer: stream it and generate checksums on the fly. Then distribute the torrent, and seed sections at a time. It can also be distributed on IPFS.

I've seen a lot of torrents being used for distributing neural network (mostly stable diffusion forks).

Good point. Let me think through this. I have about 15T free space so this can be seeded separately in ~12 batches.

You can also distribute different torrents, it's easier.

Or multiple IPFS CIDs. I think you can have a "directory" (CID) that contains multiple CIDs, and only need the content hashes to build it.

You can also publish multiple CIDs and ask people to seed random ones; that's how Libgen does it (and is similar to the multiple torrents concept).

The same file can be used to seed both torrents and IPFS.
