  • The NBU for NDMP manual also contains diagrams that makes it easy to understand the difference between direct attached and 3-way.

    3-way simply means a NAS filer does not have own devices, but is sending data to another NAS filer that has tape drive(s) attached.

    The backup policy will tell you how it is configured - look at the Storage Unit name in attributes. 
    Then look at Client name in the same policy.
    If STU and Client name is the same, then it is one-way (direct attached).
    If STU name is for one filer but another filer name in Clients tab, the config is 3-way.
