You can create an override for a property or configuration parameter for a recovery. A property override changes the default value of a recovery property, and a configuration override changes the default value of a custom configuration setting for the recovery. If you want to create an override for a recovery, use the Microsoft.EnterpriseManagement.Configuration.ManagementPackRecoveryPropertyOverride or Microsoft.EnterpriseManagement.Configuration.ManagementPackRecoveryConfigurationOverride class. These classes are derived from the Microsoft.EnterpriseManagement.Configuration.ManagementPackRecoveryOverride class.

Only the Enabled property can be overridden for recoveries. To figure out which parameters can be overridden, you must look at the definition of the recovery in the Management Pack that defines the recovery. All the parameters that can be overridden are defined in the OverrideableParameters element of the recovery. You can also call the GetOverrideableParameters method to get the list of parameters programmatically.

The following example creates an override for the Enabled property of a recovery.
