      Hi Anita,

      Offline backup is completed successfully but not able to take online backup.

      after some analysis mount point in aix related like sapdata1-n, logs and archive are not mounted with option read read and cio, may this is the issue.

      in note 948294 the mount point should be with option cio, but not sure beacuse take downtime to remount all.

      After this only will sure whats the root cause for the same.

    BR0051I BRBACKUP 7.20 (1)

    Could you apply patch for current BR*tools version with the latest available at SMP to check again ?You could refer SAP Note  1723121 - Corrections in BR*Tools 7.20 patch 24     

    or best would be to apply the latest for version 7.20.

    Hope this will help you.

    Good luck !!
