You could - but why not make the boot partition also the ( potential ) system partition. I do it on all my o/s installations.
Create the boot critical files on each o/s partition.
Then, just choose which to use as the system partition by handing the Active flag to whichever you want.
To include more than one volume, e.g. C and S
WBADMIN START BACKUP -BACKUPTARGET:G: -INCLUDE:C: ,S: -QUIET
You could use a volume name - but it is easier to give the system volume drive letter S.
