       The nnssrrmmmmddbbaassmm is a standard,  external  ASM  (Application
       Specific Module) that assists in the saving and recovering
       of the NetWorker media multiplexor's database files.

       See uuaassmm(8) for a general description  of  ASM's  and  the
       [_s_t_a_n_d_a_r_d_-_a_s_m_-_a_r_g_u_m_e_n_t_s].   It is intended that nnssrrmmmmddbbaassmm
       only be invoked by ssaavveeggrrpp(8) or mmmmrreeccoovv(8) operations.

       Actions performed by nnssrrmmmmddbbaassmm, specific to the NetWorker
       application during a ssaavvee are:

       Architecture independence:
              The  high  speed access methods and data structures
              implemented by the database code are machine depen-
              dent.  This ASM saves only the records (and not ac-
              cess indexes) in an architecture  independent  man-
              ner.   Therefore,  NetWorker media databases may be
              saved from one machine architecture  and  recovered
              to another.

       Conservation:
              Since  only  changed records are saved, and not in-
              ternal indexes, considerable network bandwidth  and
              tape space are conserved.

       The  rreeccoovveerr  operation  of this ASM is the inverse of the
       ssaavvee operation.
