    If you want to match `git clone --mirror`, which would include your
    refs such as `refs/remotes/*`, use `--all`.

Notes (series):
    v3:
    • Elaborate on “full backups” in Examples instead
    • Just point to the section in the second paragraph where everything is
      elaborated
    • Incorporate some of Junio’s suggestions:
      • Mention what the “full backup” here does not include
    
        Link: https://lore.kernel.org/git/xmqqh68q1l37.fsf@gitster.g/
        Link: https://lore.kernel.org/git/xmqqzfmiza69.fsf@gitster.g/#t
    • Remove the final paragraph pointing to Examples now that we mention it
      in the second paragraph
    v2:
    • Mention as a parenthetical on an existing paragraph (don’t create a
      new sentence and paragraph)
    • Remove the “mirror” mention

-Assume you want to transfer the history from a repository R1 on machine A
-to another repository R2 on machine B.
+We'll discuss two cases:
+
+1. Taking a full backup of a repository
+2. Transfer the history of a repository to another machine when the two
+   machines have no direct connection
+
+First let's consider a full backup of the repository.  The following
+command will take a full backup of the repository in the sense that all
+refs are included in the bundle (except `refs/stash`, i.e. the stash):
+
+----------------
+$ git bundle create <file> --all
+----------------
+
+But note again that this is only for the refs, i.e. you will only
+include refs and commits reachable from those refs.  You will not
+include other local state, such as the contents of the index, working
+tree, per-repository configuration, hooks, etc.
+
+For the next example, assume you want to transfer the history from a
+repository R1 on machine A to another repository R2 on machine B.
 For whatever reason, direct connection between A and B is not allowed,
 but we can move data from A to B via some mechanism (CD, email, etc.).
 We want to update R2 with development made on the branch master in R1.
