I have few questions regarding the licensing of SQL Server when it comes to Always On:
Under which scenario / settings we can say that secondary replica is truly passive and will not be considered for licensing:
- "Readable Secondary" AG setting for all the replicas associated to Always On(including current Primary replica) should have setting either as “NO” or “Read-Intent Only” or it should be "NO" only?
- There should not be any Standalone Database? (not even any third party backup tool database such as "LiteSpeedLocal").
- Also the backup should not be configured to run on Secondary replica. Otherwise, the Secondary replica will not be truly passive. Is it true?
Any other things which we need to consider / look for in order to be 100% sure that the secondary replica will not require license?
