Error description

  • The IBM Spectrum Protect Backup-Archive Client supports snapdif
    backup of the following configurations:
    -
    Windows: The snapdiff (snapshot difference) option is for
    backing up NAS/N-Series file server volumes that are CIFS
    attached.
    -
    Linux: The snapdiff (snapshot difference) option is for backing
    up NAS/N-Series file server volumes that are NFS attached.
    -
    The IBM Knowledge Center and PDF content incorrectly indicate
    that snapdiff can use both CIFS and NFS volumes on both Linux
    and Windows.  Documentation in the following locations should be
    updated to eliminate any confusion about which filesystems are
    supported for snapdiff backup on given platforms.

    "(Windows) The snapdiff option is for backing up NAS/N-Series
    file server volumes that are CIFS attached.
    
    (Linux) The snapdiff option is for backing up NAS/N-Series file
    server volumes that are NFS attached. "
