Excluding Folders in a Backup

I have a script that runs as a scheduled task. This is the line in the script that starts a backup:

WBADMIN START BACKUP -backupTarget:\\BackupStorage\backup\BackupA -allCritical -include:c:,d:,f: -vssfull -quiet  >> D:\BackupLogs\backupLogsForA.txt

I now need to exclude two folders on the D: drive. It is my understanding that with the -allCritical switch it will ignore -exclude.

My question is, what will I lose if I replace -allCritical with -SystemState and then add the excluded folders? Can I still recover from bare metal with this backup? 

Thanks in advance for your help!
