Network File System (NFS)
Glossary-8
the host name, and each tape drive attached. The install subdirectory in the Oracle
Secure Backup home includes a sample network description file named obndf.
Network File System (NFS)
A client/server application that gives all network users access to shared files stored on
computers of different types. NFS provides access to shared files through an interface
called the Virtual File System (VFS) that runs on top of TCP/IP. Users can manipulate
shared files as if they were stored on local disk. With NFS, computers connected to a
network operate as clients while accessing remote files, and as servers while providing
remote users access to local shared files. The NFS standards are publicly available and
widely used.
OB access mode
A synonym for primary access mode.
obfuscated wallet
A wallet whose data is scrambled into a form that is extremely difficult to read if the
scrambling algorithm is unknown. The wallet is read-only and is not protected by a
password. An obfuscated wallet supports single sign-on (SSO).
obtar
The underlying engine of Oracle Secure Backup that moves data to and from tape.
obtar is a descendent of the original Berkeley UNIX tar(2) command.
Although obtar is typically not accessed directly, you can use it to back up and restore
files or directories specified on the command line. obtar enables the use of features not
exposed through obtool or the Web tool.
obtool
The principal command-line interface to Oracle Secure Backup. You can use this tool
to perform all Oracle Secure Backup configuration, backup and restore, maintenance,
and monitoring operations. The obtool utility is an alternative to the Oracle Secure
Backup Web tool.
offsite backup
A backup that is equivalent to a full backup except that it does not affect the full or
incremental backup schedule. An offsite backup is useful when you want to create an
backup image for offsite storage without disturbing your incremental backup
schedule.
on-demand backup
A file-system backup initiated through the backup command in obtool or the Oracle
Secure Backup Web tool. The backup is one-time-only and either runs immediately or
at a specified time in the future. An on-demand backup contrasts with a scheduled
backup, which is initiated by the Oracle Secure Backup scheduler.
operator
A person whose duties include backup operations, backup schedule management,
tape swaps, and error checking.
Oracle Secure Backup home
The directory in which the Oracle Secure Backup software is installed. The Oracle
Secure Backup home is typically /usr/local/oracle/backup on UNIX/Linux and
C:\Program Files\Oracle\Backup on Windows. This directory contains binaries
