Glossary-7
logical unit number
Part of the unique identifier of a tape device . See Oracle Secure Backup logical unit
number and SCSI LUN .
manual certificate provisioning mode
A mode of certificate management in which you must manually export the signed
identity certificate for a host from the administrative server , transfer it to the host,
and manually import the certificate into the wallet of the host. Unlike automated
certificate provisioning mode , this mode is not vulnerable to a possible (if extremely
unlikely) man-in-the-middle attack.
media family
A named classification of backup volume s that share the same volume sequence file ,
expiration policy , and write window .
media server
A computer or server that has at least one tape device connected to it. A media server
is responsible for transferring data to or from the devices that are attached to it.
NAS
See Network Attached Storage (NAS)
native access mode
A synonym for primary access mode .
NDMP
See Network Data Management Protocol (NDMP)
NDMP access mode
The mode of access for a filer or other host that uses Network Data Management
Protocol (NDMP) for communications within the administrative domain . NDMP
access mode contrasts with primary access mode , which uses the Oracle Secure
Backup network protocol. Note that Oracle Secure Backup uses NDMP for data
transfer among hosts regardless of whether a host is accessed through the primary or
NDMP access modes.
Network Attached Storage (NAS)
A NAS server is a computer on a network that hosts file systems. The server exposes
the file systems to its clients through one or more standard protocols, most commonly
Network File System (NFS) and CIFS.
Network Data Management Protocol (NDMP)
An open standard protocol that defines a common architecture for backups of
heterogeneous file servers on a network. This protocol allows the creation of a
common agent used by the central backup application, called a
data management
application (DMA) , to back up servers running different operating systems. With
NDMP, network congestion is minimized because the data path and control path are
separated. Backup can occur locally—from a file server direct to a
tape drive —while
management can occur centrally.
network description file
A text file that lists the hosts in your network on which Oracle Secure Backup should
be installed. For each host, you can identify the Oracle Secure Backup installation type,
