Trying to learn about SCM history/revision/restore algorithms, especially GIT

Question

I'm trying to dig up resources on how version control algorithms operate on data, and I'm especially interested in the way git's mechanism operates. I realize git does many different things, but in particular I'm interested in how history is saved and restored. I'd appreciate any links or article references anyone can point me to. thanks :)

Answer 1

If you know how to use git and what it does, but you're curious how, then dig into gitcore-tutorial for start, it shows what objects are stored inside git repository, how it stores next revisions, what is revision and how to do it manually, how revisions are connected and so on.

This presentation is also helpfull in terms of showing how it all works. It was created by maintainer of git-scm page and one of github stuff, so he knows what he talks about.
