Because every working copy is equal.  They all have a copy of the
project's metadata in the .git/ directory.

If you want a backup, create one with clone and push to it every
so often, e.g.:

  # one time setup
  $ git clone --bare . /some/other/drive/project.git
  $ git remote add backup /some/other/drive/project.git

  # then every once in a while, or from a cron job
  $ git push --all backup

Of course since Git is distributed you can you use this same approach
to make backups to other systems.  You can even edit the .git/config
to give the [remote "backup"] section more than one url line, so
that "git push --all backup" will send updated copies to multiple
locations at once.

Who needs a central repository like SVN or CVS when you can have 3
or 4, on just as many disks, in different buildings, and possibly
different parts of the world.  Yes, I keep my real work that I care
about backed up under different providers, with their data centers
located in different countries.  And of course extra copies locally,
in case the 'net is down.
