In order to back up three storage groups at the same time, you will need
to launch three separate instances of Data Protection for Exchange.
For example, in a batch file it would look something like this:

START TDPEXCC BACKUP SG1 FULL >> SG1.LOG
START TDPEXCC BACKUP SG2 FULL >> SG2.LOG
START TDPEXCC BACKUP SG3 FULL >> SG3.LOG

You may want to play around with some of the START parameters
to fit your needs.. but don't use the /WAIT option since that option
with force serialization. This should get you started.

Thanks,
