A NAS file servercan have the characteristics of both anode and a data mover.Network Basic Input/Output System (NetBIOS)A standard interface to networks andpersonal computers that is used on localarea networks to provide message,print-server, and file-server functions.Application programs that use NetBIOSdo not have to handle the details of LANdata link control (DLC) protocols.Network Data Management Protocol (NDMP)A protocol that allows a networkstorage-management application tocontrol the backup and recovery of anNDMP-compliant file server, withoutinstalling vendor-acquired software onthat file server.network data-transfer rateA rate that is calculated by dividing thetotal number of bytes that are transferredby the data transfer time. For example,this rate can be the time that is spenttransferring data over a network.node A file server or workstation on which thebackup-archive client program has beeninstalled, and which has been registeredto the server.node nameA unique name that is used to identify aworkstation, file server, or PC to theserver.node privilege classA privilege class that gives anadministrator the authority to remotelyaccess backup-archive clients for a specificclient node or for all clients in a policydomain.

Contrast with closedregistration.operator privilege classA privilege class that gives anadministrator the authority to disable orhalt the server, enable the server, cancelserver processes, and manage removablemedia. See also privilege class.options fileA file that contains processing options. OnWindows and NetWare systems, the file iscalled dsm.opt.

When a file is recalled usingnormal or migrate-on-close recall mode, itis always returned to its originating filesystem.orphaned stub fileA file for which no migrated file can befound on the Tivoli Storage Managerserver that the client node is contactingfor space management services.
