You can simulate git via:

mkdir v2 ; cp -rp v1 v2

I think a closer example at the filesystem level would be

  rsnapshot alpha

rsnapshot [1] uses hard links when it can to create a delta of changed files. Reverting can be done with rsync or cherry picking files. git blame would have to be done via something like auditd and syslog and nowhere near as easy as using git. I use rsnapshot to back up my git repos in the event they get corrupted.

Probably rsync is smarter than my cp -rp example.

Folk who are downvoting my original comment really don't understand how git version controls at the atomic level.

or use cp --recursive --preserve --link so that the copy occupies almost no space. Of course this relies on your editor not editing in place.

Cool now do a git blame

git push? git rebase?

These are tools you'd need to write atop the version dirs.

So you can't really then simulate git with:

mkdir v2 ; cp -rp v1 v2

can you?

The fundamental git model you can. The tools needed are above that in some form such as diff. git does the equivalent. Stop being pedantic.
