How to configure Sql Server to reduce CPU Utilization on Backups
Description
In some cases, the backups for those SQL server clients could affect all CPUs with High Utilization. There are some settings that can be modified to reduce the amount of CPU utilization that the backup can use.
Cause
The cause for the high utilization is the value placed in "VDI Streams / Compression Threads(*)" when set too high it creates higher than expected CPU Utilization.
Resolution
The following setting needs to be changed in order to limit the processing power utilized for the backups of the SQL Server clients.
Note: Changing these settings could affect the performance of the backups
On the WebUI, under "Jobs" section, select "Manage Sets".
Under "Set Type", select "Plugin Options".
Select the Plugin for SQL Server and hit the "Edit" button located at the bottom.
Change the "VDI Streams / Compression Threads (*)" setting to 1 and hit "Save". The next backup, the SQL Server client is going to use less processing power. If the CPU utilization is low, increase the setting's value and monitor processing power to see if it is acceptable, otherwise change it back to 1.
