You have to ask developers. There are a mutex in the VSS code which limits a number of concurrent VSS jobs. I'm not sure why it is there. Is it a limitation of VSS or Bacula?

Not possible at all?
No one tested?
Or no one cares?
Would be really nice to know if it should be possible to run more than
one backup job per machine.
