and configuration files. The contents of the directory differ depending on which role is
assigned to the host within the
administrative domain .
Oracle Secure Backup logical unit number
A number between 0 and 31 used to generate unique attach point names during device
configuration (for example,
/dev/obt0
,
/dev/obt1
, and so on). Although it is not a
requirement, unit numbers typically start at 0 and increment for each additional device
of a given type, whether
tape library or tape drive .
The Oracle Secure Backup logical unit number is part of the name of the attach point .
Do not confuse it with SCSI LUN , which is part of the hardware address of the device.
Oracle Secure Backup user
An account defined within an Oracle Secure Backup administrative domain . Oracle
Secure Backup users exist in a separate namespace from operating system users.
overwrite
The process of replacing a file on your system by restoring a file that has the same file
name.
originating location
A location where a volume was first written.
Preferred Network Interface (PNI)
The preferred network interface for transmitting data to be backed up or restored. A
network can have multiple physical connections between a client and the server
performing a backup or restore on behalf of that client. For example, a network can
have both Ethernet and
Fiber Distributed Data Interface (FDDI) connections between
a pair of hosts. PNI enables you to specify, on a client-by-client basis, which of the
server's network interfaces is preferred.
preauthorization
An optional attribute of an Oracle Secure Backup user . A preauthorization gives an
operating system user access to specified Oracle Secure Backup resources.
primary access mode
The mode of access for a host that uses the Oracle Secure Backup network protocol for
communications within the
administrative domain . Oracle Secure Backup must be
installed on hosts that use primary access mode. In contrast, hosts that use NDMP
access mode do not require Oracle Secure Backup to be installed. Note that Oracle
Secure Backup uses Network Data Management Protocol (NDMP) for data transfer
among hosts regardless of whether a host is accessed through the primary or NDMP
access modes.
private key
A number that corresponds to a specific public key and is known only to the owner.
Private and public keys exist in pairs in all public key cryptography systems. In a
typical public key cryptosystem, such as RSA, a private key corresponds to exactly one
public key. You can use private keys to compute signatures and decrypt data.
privileged backup
A file-system backup operation initiated with the
--privileged
option of the
backup
command. On UNIX and Linux systems, a privileged backup runs under the
