previous AIJ backup did not complete

  Explanation:  It appears  that  the  previous  AIJ  file  backup
  process,  which  was  started on the indicated date/time, either
  failed or was prematurely terminated by the user.

  User Action:  No user action required.  The current  AIJ  backup
  will  backup the complete AIJ file to ensure there is no loss of
  transactions.  The AIJ file created by the failed backup utility
  MUST be preserved; DO NOT discard the AIJ backup file created by
  the failed backup utility.  Even though the AIJ  backup  failed,
  the  AIJ  backup  file  must be used for successful roll-forward
  operations.
