In IntelliJ you can look at local history of a file and see that the ide remembers your changes for a long time. It seems to take a snapshot on actions like test runs, build complete, or maybe every few minutes. This is on top of auto saving and git of course. It saved my ass when I ran the wrong git command more than once!
For me this is what I use Git for, even if I have no intention of pushing to a remote repository. So I suppose some of Git's functionality could be considered redundant if only the applications would be generous about saving history and deltas.
This lets you throw away and start over, but also gives you infinite undo even after "loading" an older version.
