This tool seems very promising and does solve a real issue I've certainly had quite a few times already where this would have been very useful.

I really like the website design and content-wise, as well as the detailed writeup here on HN. Certainly impressive work for an individual.

I've never used Time Machine but I do have kopia set up for frequent backups of important places, like the entire Documents folder. It does use a CAS as well and last time/size/hashes for determining what to save.

Coming from that I'm curious about a few aspects. Would this work well for larger folders/files? You mentioned deduplication, but does that happen on the file level or on chunks of the file, so that small changes don't store an entire new version of the file? Additionally, are the stored files compressed somehow, probably a fast compression algorithm? I think that could make it work for more than just source code.

Great project though, so far. I could see it becoming a lot more popular given an open source code base. Maybe a pricing model like the one Mac Mouse Fix uses would work, being open source and charging a fee so small it still reaches a large audience. That would likely be fair considering the developer time/agent cost of just a single unf'd problem as ROI.
