Chapter 5. Data Guard Protection Modes

Protection mode decision is crucial and database administrators need to work with IT managers and other responsible people to determine RTO (Recovery Time Objective) and RPO (Recovery Point Objective) values and to select the most appropriate mode for their Data Guard configurations. After the decision is made, setting the data protection mode is a simple operation that can be performed by SQL*Plus, Data Guard command-line interface (DGMGRL) or Enterprise Manager Cloud Control.

Data Guard offers three data protection modes, which meet different business requirements as mentioned in Chapter 1, Getting Started.

The following are the different modes:

  • Maximum Protection
  • Maximum Performance
  • Maximum Availability
