I find the description a bit confusing, is there and example where we can see the usage?

My top level being that it's a VCS (like Git) specialized for binaries; with commands baked in to prevent the slowdown that often comes with large git repositories.

Specifically, it's for ELF binaries built in such a way that adding a new function or new data does not break however they cache existing functions/data.

I wonder if this concept could be extended to other binary types that git has problems with, were you able to know/control more about the underlying binary format.

One of the authors here, thanks for the feedback. We've tried to improve it here: https://github.com/elfshaker/elfshaker/pull/59

Same here. There is a usage guide, which helped a tiny bit: https://github.com/elfshaker/elfshaker/blob/main/docs/users/...

Honestly, I sort of looked at it for conventional backup strategy...as in, i wonder if it could work as a replacement for tar-zipping up a directory, etc. But, not sure if the use cases is appropriate.

Author here. We'd love this to be a thing, but this is young software, so we don't recommend relying on this as a single way of doing a backup for now. Bear in mind that our main use case is for things that you can reproduce in principle (builds of a commit history, see manyclangs).

I appreciate your response, and thanks very much for the clarification of use case; very helpful! Thanks also of course for building this!

For backup you probably want something like Borg to handle deduplication of identical content between backups.

Author here, I agree with xdfgh1112, please take care before using brand new software to store your backups!

Yes, any time that i use something new or different (or both) for something as essential as backups, i take great and deliberate care...and test, test, test...well before standardizing on it. ;-)

There is an associated presentation on manyclangs at LLVM dev meeting. I think they presented yesterday?

Unfortunately it won't be uploaded until later but it will show up on the llvm YouTube channel:

I would guess it’s a way to quickly bisect on compiler versions.
