so, i don't know why it isn't working like you expect it.
i've got 4 servers and they backup in parallel one job per server.
bacula-dir.conf
Director: "Maximum Concurrent Jobs" = 10
Storage: "Maximum Concurrent Jobs" = 4
Anyway you have set "Maximum Concurrent Jobs" in bacula-dir for
client4,5,7 as you want only start 1 job per computer?
And the backup jobs share write to a volume in the same pool?
