I have Amanda working with the default settings for the client:

  service amanda
  {
          disable         = no
          socket_type     = dgram
          protocol        = udp
          wait            = yes
          user            = backup
          group           = disk
          groups          = yes
          server          = /usr/local/libexec/amandad
          server_args     = -auth=bsd amdump
  }

Is it better to use tcp and stream since with udp there is no error
correction or does Amanda build in the error checking at the
application level?  Any other settings that would be preferred over
what is shown above?

Thanks.
