menu interface: the administrator or client-based user interface provided by VERITAS NetBackup for individuals who do not
have GUI capabilities (see “graphical user interface,” “command line interface”).
multiple volume device: a physical storage device not requiring manual intervention to change volumes because of built-in
robotic controls (see “single volume device”).
multiplexing: streaming data from multiple, simultaneous backups to the same device.
NFS mounts: files residing on a remote node that are mounted on the local node through the Network File System (NFS)
protocol.
primary storage: online magnetic disk storage connected directly to a client or server where new or active data is
maintained (see “secondary storage”).
raw partition restore: physical backup of a partition of a disk drive.
removable media: a tape cartridge or optical disk that is not permanently mounted in a secondary storage device.
restore: the act of returning a previously backed up or archived file to primary storage from secondary storage.
retention level: a factor specifying how long backups or archives are to be saved before being deleted.
robotic: performing a complex mechanical task ordinarily ascribed to human beings (such as choosing one of several
removable media and loading it into the drive of a secondary storage device).
robotic database: the Media Manager database containing information about the robotic controls for the storage devices
included in the device database (see “device database,” “volume database”).
secondary storage: supplemental storage connected to a storage server where data from primary storage is backed up or
archived (see “primary storage,” “removable media”).
secure client: a client that does not require a /.rhosts file entry for the server (see “trusting clients”).
single volume device: physical storage device requiring manual intervention to change volumes (see “multiple volume device”).
standalone device: physical storage device requiring manual intervention to change volumes (see “single volume device”).
storage domain: a single NetBackup master server and its associated media servers
storage media: any object upon which data can be stored, such as tapes, tape cartridges, and magnetic or optical disks.
storage unit: as used by VERITAS NetBackup, a logical entity that includes one or more storage devices that are of a specific
type and media density and attach to a specific host.
true image recovery: restores only files that were in the directory at the date and time of a specific backup. Previously
deleted files are ignored.
trusting client: a client that has a /.rhosts file entry for the server (see “secure clients”).
user: a person operating a client workstation (see “administrator”).
volume: any physical storage medium such as a tape or optical disk.
volume database: the Media Manager database containing information about the volume handling during backup and
restore operations (see “device database,” “robotic database”).
