We have on-premise Exchange servers in a DAG, and presently have three backup jobs related to Exchange and Active Directory.
Backup #1 gets the Microsoft Information Store on one of the Exchange servers. This job gets all the Databases and Logs.
Backup #2 is a Simplified Disaster Recovery backup of the Domain Controller, which includes drives, System State and Active Directory.
Backup #3 is a Simplified Disaster Recovery backup of the Exchange Server, which includes the Drives and System State, but not the Microsoft Information Store.
Do I need the third backup job? Would I ever need to restore something from the flat files or System State of the Exchange Server?

Yes, In case you cannot boot in the operating system. You can use SDR to recover the OS.
