I made a deduplicating version control system for large binary file based around the Restic chunker library: https://github.com/akbarnes/dupver

I like to think that this (well, deduplicating version conrol in general, not my crufty project) will be the future of version control and we'll leave the ugliness of git-lfs behind us. For now at least it's a fun project.

Edit: There is an existing project called Boar that does the same thing, though it appears to have been abandoned and is stuck in Python 2
