Configuring Performance Throttling

You can limit computer processing (CPU) resources assigned for Veeam Plug-In backup jobs. This setting allows you to reduce the impact of backup operations on the target computer performance. Performance throttling prevents Veeam Plug-Ins from utilizing all computer resources to ensure that enough resources are provided for other operations. This maybe useful in case you detected that your source database responses are slower during backup operations.

If you throttle performance, additional system components help with the throttling process:

• [For Linux and Unix machines] Veeam Backup & Replication starts Veeam Plug-In backup operation processes with low priority and nice value of 19. The nice values are in ascending order of priority ranging from -20 (the highest priority) to 19 (the lowest priority).
• [For Microsoft Windows machines] Veeam Plug-In uses the OS process priority system in the background to lower the priority of backup operation processes. To learn more about the process priority setting, see this Microsoft article.

Keep in mind that Veeam Plug-Ins manage the priority of backup operation processes only if the system running on the target computer is busy with other tasks.

To throttle Veeam Plug-In performance, do the following:

1. Navigate to the Veeam Plug-In for Oracle RMAN directory on your Oracle server. The path to the directory differs depending on the OS of the machine where Veeam Plug-In is installed:

• On machines running Linux or Unix OS: /opt/veeam/VeeamPluginforOracleRMAN
• On machines running Microsoft Windows OS: %PROGRAMFILES%\Veeam\VeeamPluginforOracleRMAN

2. Start the Veeam Plug-In configuration tool with the following parameter:

• On machines running Linux or Unix OS:

• On machines running Windows OS:

3. To confirm that you want Veeam Plug-In throttle performance, type y.
