AIJ backup completed when accessing unmodified journal <str>

  Explanation:  An attempt was made to backup an after-image
  journal that has not been modified.  This normally occurs when a
  "by-sequence" is done out of order (For instance, sequence 6 is
  backed up, then sequences 5 through 7 are attempted).

  User Action:  In the above example, the backup was completed
  when the previously backed up AIJ sequence  6 was encountered;
  the journal containing sequence  5 was fully and safely backed
  up.  Restart the backup with the next journal requiring backup
  (in the above example, sequence  7).
