I dont understand why "having concurent jobs" is wrong. I have tens of clients, 
hundereds of jobs. The clients are on slower lines than the storage daemon, and 
when Incremental job is on, the traffic is nearly zero. My director with 
storage daemon can manage about 20 concurent jobs. The load is higher but now 
DOS at all.

Is there a more conviened way to see priorities for jobs
then to check then one after one in bconsole?


| *run job=c1job
| Run Backup job
| JobName:  c1job
| Level:    Incremental
| Client:   c1-fd
| FileSet:  rootboothomevar
| Pool:     Default (From Job resource)
| Storage:  File (From Job resource)
| When:     2012-10-10 08:12:08
| Priority: 10
| OK to run? (yes/mod/no): .
| Job not run.

I don't understand that question.  Perhaps should I read it as:
  How to create a denial-of-service attack
  with my bacula clients on my bacula server?
  And how to check the current attack count?


I think that
> You need to take sure that the jobs have the same Priority.
could help with doing stupid things.
However to make the DoS attack succeed, is more needed.
Like making several definitions of the same storage deamon
and hope that the Bacula schedular eats the bait.


In other words:

   When are more concurrent jobs then just one backup job wanted?
