2 Introduction

This guide to Backing up and Restoring a Database describes the functionality, installation, configuration and adminstration of the NetWorker component “Net- Worker Save and Restore for ORAcle (NSR-ORA)” V3.2. This software compo- nent allows to integrate ORACLE databases into the Networker data backup concept.

NetWorker is intended for automatic data backup in heterogeneous networks. Among its advantages are the large number of supported backup media and simple user prompting in spite of the wide range of functions. However, the backup of database files with NetWorker is only possible offline. Where a data- base needs to be recovered, NetWorker can restore the faulty files and return the database to a consistent, updated status, although additional steps need to be performed with ORACLE tools.

NSR-ORA closes the gap between NetWorker and ORACLE as it can commu- nicate with both of them. It can be used to back up ORACLE databases online or offline. Backup is possible in normal and compressed modes. Whether the database is located in a Unix file system or on raw devices is immaterial. When using NetApp NAS filers the database can be backed up on tapes and also as a snapshot on the NAS filer directly. The database (thus also NSR-ORA) and the NetWorker server need not be installed on the same computer; database backup is also possible from NetWorker clients.

NSR-ORA enables you to initiate the recovery of an inconsistent database to a specific second automatically. NSR-ORA automatically checks the status of the database and commences the required restore and recovery measures to restore the current status. This means that you can perform a database recov- ery at any time even without any knowledge of ORACLE (you will find further information about recovery in the chapter “Recovery”).

For a better understanding of the database interface, the fundamental ORACLE database terms are described briefly below:

The physical database structure

The logical database structure

The database backup

Archive mode of the database.
