Restoring File-system Backups with Oracle Secure Backup
Learning Objective
After completing this topic, you should be able to
recognize how to restore file-system backups with OSB
1. Browsing a backup catalog
The administrative server maintains a catalog in which it stores metadata relating to
backup and restore operations for the administrative domain. Oracle Secure Backup,
abbreviated as OSB, maintains a discrete backup catalog for each client in your
administrative domain.
raphic
The Restore page of the OSB Web tool is opened.
Supplement
Selecting the link title opens the resource in a new browser window.
Learning !i"
Use the learning aidStyle consi"erationsfor more information on the style
considerations for the Oracle 11gatabase used in this course.
!hen you browse a backup catalog, OSB presents the data in the form of a file"system
tree, #ust as it appeared on the client from which the data was saved. $or e%ample, if you
backed up the &home&myfile.dat file located on myhost, the backup catalog for myhost
represents the contents of the backup image as &home&myfile.dat.
raphic
The Restore: Backup Catalog page is opened.
't the root of the backup catalog is the superdirectory, which contains all files and
directories saved from the uppermost file"system level. The superdirectory provides you
with a starting point from which you can access every top"level file"system ob#ect stored
in the backup catalog. $or !indows clients, this superdirectory contains drive identifiers,
such as the ( drive.

The superdirectory that lists all the file-syste ob!ects is opened.
)ou can restore f iles to the original location or to an alternative location. The end"user
restore ability is based on user"level permissions.
OSB automatically recalls tapes located at alternate locations for the restore operation.
*The restore #ob remains in a pending state until tapes are returned to an accessible tape
device.+ $ast restoration from the tape is accomplished using the tape position data
obtained during the backup operation.
!ith OSB, you can restore data in two different ways
catalog-base" restore an"
(atalog"based restore involves browsing backup catalogs for the file"system ob#ects. 'fteryou have located their names and selected the instances to restore, you can direct OSB to
perform the restore operation.
The catalog offers two options to restore the re-uired files tree"style *browsing of all
backups+ and multiple -uery options *for fast identification of re-uired files+.
raw restore
Using raw restore involves knowing the names of the file"system ob#ects of interest and the
secondary storage location *volume / and backup image file number+ in which they are
stored.

operation
2. 'n end user must have admin permissions to restore the file"system data
3. )ou must know the names of the file"system ob#ects to restore them

Option 1:This option is correct. "ou can restore the file-syste data to the
original location or to an alternati#e location.

Option 2:This option is correct. OSB autoatically recalls tapes located at
alternate locations for the restore operation. The restore !ob reains in a pending
state until tapes are returned to an accessible tape de#ice.
Option 3:This option is incorrect. The end-user restore ability is based on user-
le#el perissions. But the end user doesn$t necessarily need adin perissions.
Option 4:This option is incorrect. "ou can restore file-syste files with OSB using
a catalog-based restore operation or directly fro the edia. Restoring directly
fro the edia re%uires you to know the naes of the file-syste ob!ects of
interest and the secondary storage location in which they are stored.

Learning Objective
After completing this topic, you should be able to
recognize how to manage an OSB domain
1. anaging OSB "aemons
To oversee data protection activities among diverse hosts, devices, and databases, you
define an administrative domain. There must be only one administrative server for each
administrative domain.
The administrative server contains two components
Oracle Secure Backup, abbreviated as OSB, catalog is a directory structure with host"specific
subdirectories. This means the contents vary depending on the roles you assign to the host. 'nadministrative server has a central catalog with configuration and metadata.
aemons *or services+ are processes that run in the background and perform OSB operations on
behalf of an application. Some daemons run continuously? others run only to perform a specific
work and then e%it when they have finished.
The OSB daemons actively participate in managing backup and restore operations.
observiced
On the administrative server, the observiceddaemon runs #obs *such as backup and
restore operations+ on the re-uest of the obscheduleddaemon, cleans up old log files
and transcripts, and provides access to the OSB configuration data to other hosts in the
domain.
The observiceddaemon starts the obscheduleddaemon and the web server during
initialiation. !hen running on a client or media server, the observiceddaemon is
primarily responsible for invoking OSB programs in response to a re-uest from the
administrative server.
On all hosts, the observiceddaemon is usually started as a part of system startup and
runs continuously. On U7/= and Cinu%, the startup is usually performed through entriesin &etc&init.d, whereas on a !indows host, the observiceddaemon is started by Service
(ontrol Aanager.
obscheduled
The obscheduleddaemon initiates scheduled events and manages #obs. This daemon
receives #ob creation re-uests from obtool users and from the system backup to tape, also

). anaging "e2aults an" policies
efaults and policies are configuration data that control how Oracle Secure Backup,
abbreviated as OSB, operates within an administrative domain. The data is maintained on
the administrative server. OSB is preconfigured with a set of defaults and policies for fast
deployment in most environments.
OSB policies are grouped into several policy classes. >ach policy class contains policies
that describe a particular area of OSB operations.
ifferent types of policies are

whether OSB updates the backup history data every time a client host is backed upThis can be specified by selecting an option fro the uto history drop-down list. The yes option is
currently selected.
whether OSB creates volume and backup image labels for a new backup image whenever it
backs up the data, and
This can be specified by selecting an option fro the uto label drop-down list. The yes option is
currently selected.
whether OSB performs block"level verification after each backup section is completed
This can be specified by selecting an option fro the Backup 6age recheck le#el drop-down list.
The none option is currently selected.

6. anaging OSB catalogs
The Oracle Secure Backup, abbreviated as OSB, catalog is a collection of backup
metadata catalogs and configuration files. They are centrally located on the administrative
server in a hierarchical file system under the OSBE5ome directory.
There are four primary catalogs.
File-system backup meta"ata catalog
/n the file"system backup metadata catalog, file"system backup metadata is stored for
each client in the indices.curcatalog *also known as the inde% database+. Thus, if the
administrative server has 1FF clients, it has 1FF indices.curfiles. The indices.cur
file is located in this directory.The directory path is the following:
@usr@local@oracle@backup@adin@history@host@hostnae
iece catalog
The Oracle atabase backup piece metadata is stored in the sbtpiece.datand
sbtpiece.idxfiles.
7olumes catalog
/n the volumes catalog, a listing of all tapes that contain backups registered with the OSB
catalog is stored in the volumes.datand volumes.idxfiles. !hen a tape is
overwritten, the volumes catalog is immediately updated.
Backup sections catalog
/n the backup sections catalog, information about backup sections is stored in the
archives.datand archives.idxfiles. This information is important when a backup
spans multiple volumes.
The piece, volumes, and backup sections catalogs are located in this directory.
raphic
The directory path is the following:
@usr@local@oracle@backup@adin@state@general@
'fter volumes have been overwritten or unlabeled, the backup metadata is no longer
needed. The inde% daemon automatically removes the backup metadata from the catalog
at the interval set by the indexcleanupfrequencyinde% policy. The default is 1 days.

3. store the volume set in a known location
)ou will need the catalog backup only in unusual, difficult circumstances, so you should
make special provisions when storing the backup
storing the volume set in a known location so that the tapes can be retrieved without having to
look up which volumes were used to store the backup and
configuring the operations/backupoptionspolicy to use the -voption *if you9ve configured
a scheduled backup+
(onfiguring the operations/backupoptionspolicy generates a full transcript and
lists all the files that are backed up. Then you can save the transcript along with the
tapes.
$or additional protection, you can back up the &usr&etc&ob directory, which is the #ob
transcript directory.

)ou may also want to save a copy of the S(S/ parameters that are used to create the
device special files for your tape devices. This can help you to reconfigure the tape
devices during disaster recovery of your administrative server. The parameter
specifications should be saved along with the volumes that contain the catalog backup.

The 7A6 defines a common architecture for backups of heterogeneous file servers on
a network. 7A6 allows administrators to back up data using any combination of
compliant network"attached servers, backup devices, and management applications.
!ith 7A6, network congestion is minimied because the data path and control path are
separated. Backups can occur locally from file servers directly to tape drives whereas
management occurs centrally.
7A6 is commonly used by 7etwork 'ttached Storage, also known as 7'S, devices,
which are also known as filers, to perform backup and restore operations without
re-uiring an OSB installation on the appliance.
The filer communicates with the backup software through 7A6. This model is very
different from the classic backup model, which re-uires the installation of an agent or
backup software component on each host to communicate and perform backup and
restore operations as directed by the backup software server.
7'S devices can be a client or media server but not an administrative server.
/f you select 7A6 in the 'ccess Aode drop"down list on the 'dd Aedia Server page,
you must also specify additional options for your new host on the 7A6 Settings page.
$irst select an authentication type from the 'uthentication Type drop"down list. The
authentication type defines the way in which OSB authenticates itself to the 7A6
server. Typically, you should use the 7egotiated default setting.
There are five 'uthentication Type options.
0egotiate"
The 0egotiate"option instructs OSB to negotiate with the 7A6 server to determine the
best authentication mode to use.
/e2ault
The /e2aultoption uses the value of the 'uthentication type for the 7A6 policy.
0one
The 0oneoption attempts to use the 7A6 server from OSB without providing
authentication data *this is usually unsuccessful+.
9et
The 9etoption uses plain *unencrypted+ te%t to authenticate.
/nter the values which are appropriate for your environment.

Unlike S(S/, which is a host"centric protocol, $iber (hannel libraries and tape drives are
typically shared among multiple OSB media servers. ' $iber (hannel"attached tape drive

it.
)ou can specify multiple attach points when creating a device with the mkdevor chdev

2. obtool can be used to add devices
Cibraries and tape devices attached to 7etwork 'ttached Storage, also known as 7'S,
filers are automatically configured by the operating system on which the 7'S device runs.
Both S(S/ device and $iber (hannel configuration occur automatically and re-uire no
input from the user.
OSB can detect changes in device configuration for some types of these 7A6"
accessed hosts and on the basis of this information, automatically update the device
configuration in the administrative domain.
5owever, 7'S tape libraries and tape drives must first be made accessible to the OSB
software. This is accomplished by performing device discovery on each of the 7'S filers
in the administrative domain. )ou can discover devices by using >nterprise Aanager, the
