Defining a strategy: overview

The primary objective of backing up data is to recover from the damage caused by a failure and resume normal operations as quickly as possible. This recovery can be accomplished only if you have a well-designed backup-and-recovery strategy that maximizes data protection and minimizes data loss.

To formulate an efficient strategy, begin with your recovery strategy, which defines your recovery requirements, and the recovery techniques you use to recover from various failure modes, such as media failure, user error, data corruption, and complete loss of the Oracle Database Server.

Each restore and recovery requirement imposes requirements on your backup strategy. After you have decided on your recovery strategy, you can plan your backup strategy, which will define your backup requirements, including:

•
Oracle features you use to take, store, and manage your backups
•
Backup types you implement
•
Intervals at which you schedule these backups
•
Situations in which you back up the data outside the regular schedule

Typically, when defining a backup strategy, you face a trade-off between mean time to recover (MTTR) and backup space usage.

The topics that follow provide information and guidelines that can help you formulate a backup strategy for use with the plug-in.
