You can try the Workbench Moderation module.


  Workbench Moderation adds arbitrary moderation states to Drupal core's
  "unpublished" and "published" node states, and affects the behavior of
  node revisions when nodes are published. Moderation states are tracked
  per-revision; rather than moderating nodes, Workbench Moderation
  moderates revisions.
