Hi,
if you protect using System State Protection you will be backing up the following:
- The boot files
- The COM+ class registration database
- The registry
- System files that are under Windows File Protection
If you choose BMR then you'll protect at least drive C: and also all the critical volumes for your system.
Try for each server and then add the missing volume or configure BMR to save the drive you want.
