I don't think I see any backup refs (see below for full list). But, I may be misunderstanding what they are, how to look for them. > history.

Here is the list (long!) of all I found: proj.git (BARE:master) $ git for-each-ref c718eadcf8d09d68c385f0a9355a2c871474fb43 commit refs/heads/1.0 daa75889053b70515179e334cbe3fe6fc7873ff3 commit
