Oracle Secure Backup Concepts
1-2 Oracle Secure Backup Installation and Configuration Guide
Oracle Secure Backup eliminates integration challenges with ready-to-use tape
management software that provides single-vendor support. Oracle Secure Backup also
reduces your costs. When using Oracle Secure Backup with RMAN to back up and
recover databases and files to and from tape, no third-party tape management
software is required. Oracle Secure Backup provides the media management layer
needed to use tape storage with RMAN.
Centralized administration, heterogeneous network support, and flexible scheduling
simplify and automate protection of the entire Oracle environment, including database
data and file-system data such as the contents of the Oracle home.

Oracle Secure Backup Administrative Domains and Hosts
Oracle Secure Backup organizes hosts and tape devices into an administrative domain,
representing the network of hosts containing data to be backed up, hosts with attached
tape devices on which backups are stored, and each
tape device with its attachment to
the hosts. A host can belong to only one administrative domain.
Host Roles in an Administrative Domain
Each host in an administrative domain must be assigned one or more of the following

roles :
■
Administrative server
Each administrative domain must have exactly one administrative server . During
postinstallation configuration, the administrative server must be configured with
complete data regarding the other hosts in the administrative domain, their roles,
and their attached tape devices. This configuration information is maintained in a
set of configuration files stored on the administrative server.
The administrative server runs the scheduler , which starts and monitors each
backup job . The scheduler also keeps a backup catalog with metadata for all
backup and restore operations performed in the administrative domain.
■
Media server
A media server is a host with at least one tape device attached to it. A media
server transfers data to or from a volume loaded on one of these tape devices. A
media server has at least one attachment to a tape drive or library. It might have
attachments to multiple tape libraries.
You specify the attachments between media servers and tape devices during
postinstallation configuration of Oracle Secure Backup.
■
Client
The client role is assigned to any host that has access to file-system or database
data that can be backed up or restored by Oracle Secure Backup. Any host where
