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).
