21 1 Overview of Product Software and Features This chapter includes the following major sections: Naming conventions used in this guide Importance of backups NMDA product features DB2-specific NMDA features Informix-specific NMDA features Lotus-specific NMDA features Oracle-specific NMDA features Sybase-specific NMDA features NMDA components NMDA backup and restore processes Overview of Product Software and Features 21

22 Overview of Product Software and Features Naming conventions used in this guide This guide uses the naming conventions outlined in Table 1 on page 22. Table 1 Naming conventions Term Client-side configuration Configuration wizard Server-side configuration Database host or application host Microsoft Administrator user NMC NMDA NMDB2 NMI NML NMO NMS Notes user PowerSnap snapshot backup or restore Regular backup or restore Restore and recover UNIX Windows Description Backup configuration that is created with the EMC NetWorker Management Console (NMC), withou the configuration wizard. Configuration wizard, integrated with the NMC GUI, that can be used to configure the following: NMDA DB2, Lotus Domino/Notes, or Oracle scheduled backup NMDA Oracle recovery Backup configuration that is created with the configuration wizard. Host where both the particular database or application software and NMDA software are installed. Member of the Microsoft Windows Administrators group. NetWorker Management Console user interface. NetWorker Module for Databases and Applications. NetWorker Module for DB2. NetWorker Module for Informix. NetWorker Module for Lotus. NetWorker Module for Oracle. NetWorker Module for Sybase. User that runs a Domino server or Notes client where Lotus data is being backed up or restored. Backup or restore that is implemented by using snapshot technologies through the EMC NetWorker PowerSnap x Module software. NMDA backup or restore that does not use snapshot technologies through the PowerSnap Module software. Unlike NetWorker, which uses the term recover for all backup retrieval activities, NMDA distinguishes between restore and recovery of a database: Restore means to retrieve individual datafiles from backup and store the files on disk. Recover means to apply the transaction, redo, or logical logs to make the database consistent. Both UNIX and Linux operating systems, unless specified otherwise. All the supported Microsoft Windows operating systems, unless specified otherwise. The Glossary provides a complete list of terms used in this guide. 22 EMC NetWorker Module for Databases and Applications Release 1.0 Administration Guide
