I would like to know if there are good practices for setting exclusions in the TDR or can I follow the product manufacturer's documentation.
All our documentation regarding exclusions are here: https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Fireware/services/tdr/tdr_exclusions_c.html
I you wish to exclude SQL, add the path where the database is stored to the exclusions. You'd generally exclude anything that you'd exclude your antivirus from.
