Problem conclusion

  • This problem was fixed.
    Affected platforms:  AIX, HP-UX, Solaris, Linux, and Windows.
    
    This new message is introduced with this APAR:
    ANR3639I <command>: A deduplicated NAS backup image for
    node <node name>, file space <file space> was skipped.
    Explanation: The server command has determined that a
    NAS backup image is not eligible for processing because
    the image or one of its dependent files is stored or
    had been stored in a deduplicated storage pool.
    System action: The processing continues.
    User response: No action is required.
