client. Access to OSB configuration data on the administrative server is provided by the
service daemon. It also runs jobs requested by the schedule daemon. On a media server
or a client, the daemon handles membership in an administrative domain.
Schedule daemon This runs only on the administrative server. It is the OSB scheduler.
Index daemon This daemon runs only on the administrative server, to manage the
backup catalog. It starts when a backup is completed or the catalog is accessed for
restore or browsing operations.
Apache web server daemon This runs only on the administrative server and provides
the Web tool interface.
NDMP daemon This daemon runs on a media server and a client, and provides data
communication between them.
Robot daemon This runs on a media server and manipulates tapes in a tape library. The
service daemon starts one robot daemon for each tape library when a tape manipulation
is needed.
Proxy daemon This daemon runs on a client to verify user access for SBT backup and
restore operations.
Host Access Modes
Communicating to a host in an administrative domain is possible through two access modes:
Primary For primary access mode, OSB is installed on a host. The access mode is used
by OSB daemons. An Oracle database typically exists on a host accessed via this mode.
In OEM, it is referred to as “native” access mode. In OSB Web tool, it is called “OB”
access mode.
NDMP The Network Data Management Protocol host is a storage appliance provided
by third-party vendors, such as DinoStor, Mirapoint, and Network Appliance. Using a
vendor-specific implementation, the NDMP host uses the NDMP protocol to back up and
restore file systems. OSB is accessible via NDMP, although OSB software is not installed
on an NDMP host.
Administrative Data
OSB arranges information for the administrative domain as a hierarchy of files in the OSB home
on the administrative server. The directory that OSB installed into is the OSB home.

The installer assigns a random password to the oracle user. Usually, it is unnecessary to log into
OSB by using this user.
Operating System Accounts
For OSB users, the namespace is distinct from the namespaces for Linux, Unix, and Microsoft
Windows users. Therefore, if you access a host in the administrative domain as, for example, the
operating system user backup_usr, and if the OSB user in the domain is named backup_usr, these
accounts will be managed separately, though the names are identical. You may find it convenient
to create the OSB user with the same name and password as an operating system user.
At the time you create an OSB user, you may associate the user with Unix and Microsoft
Windows accounts. Accounts of this type are used with an unprivileged backup, which is a
backup that is not run with root privileges. Privileged backup and restore operations use a client
with root (Unix) or Local System (Microsoft Windows) permissions.

Chapter 5: Oracle Secure Backup 121
If you were to create an OSB user named backup_usr and associate it with Unix account
ubackup_usr and Microsoft Windows account wbackup_usr, when backup_usr uses the backup
unprivileged command to back up a client, the jobs will run under the operating system account
associated with backup_usr. Therefore, backup_usr is only able to back up files on a Unix client
accessible to ubackup_usr, and able to back up files on a Microsoft Windows client accessible to
wbackup_usr.

user Assigned to users to allow them rights to interact in limited ways with their domains.
This class allows users to browse their own data within the OSB catalog and to perform
user-based restores.
Installing and Configuring Oracle Secure Backup
OSB is available for delivery on CD-ROM or may be downloaded from the Oracle Technology
Network (OTN) web site at the following address:
/>The following are requirements for installing and configuring OSB:
Each host in the OSB administrative domain must run TCP/IP. Static IP addresses should
be assigned to all hosts, or it should be ensured that the DHCP server always assigns the
same IP address.
There should be no duplicate host names in the OSB administrative domain, because
index catalog data is based on the client host name.
For Linux media servers, the SCSI Generic (SG) driver needs to be installed.
Each node of a RAC cluster using OSB requires an installation of OSB.

Using Oracle Secure Backup
It is not possible to perform Oracle database backup and restore using the OSB Web tool. Therefore,
we recommend using OEM as a centralized interface to schedule backup and restore jobs for
Oracle database and file system data.

Backup Cloud Module
OSB provides the ability to use storage clouds, such as Amazon S3, as offsite backup storage
destinations. To utilize Amazon S3 as backup storage, you need to sign up for Amazon S3 service
and get the Access Key ID and the Secret Access Key. After the access identifiers are collected,
they can be used to configure OSB during the OSB Cloud Module installation. The OSB Cloud
Module install tool can be downloaded from OTN at the following address: cle

Summary
Oracle Secure Backup delivers high performance and secure data protection crucial for both
offsite and local storage of mission-critical data. Complete product support from Oracle Support
Services, integration with Oracle Enterprise Manager, ability to use the Cloud as a next-generation
offsite backup storage, and excellent pricing are only a few of the many reasons for employing
OSB to meet your file system and Oracle database backup requirements. For centralized backup
tape management in mixed, distributed environments that provides a complete backup solution
for the enterprise, OSB is a strong contender.
