You can't lose anything as long as you have a pointer to it (which doubles as making it easy to find)

No need to make a "backup" branch. Learn to trust the reflog.

That is like learn to trust the indestructibility of matter. I can still lose (not able to locate...) my keys even though they still exist!

reflog doesn't keep things through gc.

the only thing that does keep a git object is having a ref that (directly or transitively) points to it
