The Customer Advantage:Complete Oracle Solution

• Oracle Secure Backup and RMAN provide an end-to-end backup solution for Oracle environments– Centralized backup management to tape for file

system data and the Oracle database– Most well-integrated media management layer for

RMAN backups– Backup of any data anywhere on the network

• A single technical support resource for the entire backup solution expedites problem resolution.

• This ensures reliable data protection at a lower cost and complexity.

Oracle Secure Backup:Backup Management Overview

• Centralized management of the administrative domain– Consolidated catalog– Users and privileges

• Ease of administration with multiple interface options, backup policies, and much more

• Backing up and restoring data– File system and Oracle database– Management through policies

• Media management (tapes)

• Automated tape device management

• Flexible configuration options

Automated Device Management

• Oracle Secure Backup automates the control of tape libraries.– Accepts SCSI commands from the library to:

Manage the tapes inventory

Move tapes to or from storage elements and drives

– Automates tape drive cleaning– Supports bar code readers and media verification

• Automated device discovery and configuration for NDMP v3 and v4 capable servers

• Two ways of backing up data– On-demand backups– Scheduled backups

• Two types of backup– Full: All specified files– Incremental: Only files that have changed since the

last lower backup

Oracle Secure Backup Jobs

• Backups using data sets:– Data set jobs: One for each data set request– Backup jobs: One for each impacted host for each

data set job

• File system file restores:– Restore jobs: One for each needed backup image

• RMAN jobs

• For each job, Oracle Secure Backup maintains:– A log – A running transcript

Two ways for restoring data

• Catalog-based restore: Based on catalog backups history

• Raw restore: Based on your memory
