I know Arno Lehmann can provide paid support if you would like that.

I believe Arno collects these. Although there is currently long wish list...

I have this set in quite a few places:
# grep -R oncurrent *
bacula-dir.conf: Maximum Concurrent Jobs = 5
bacula-fd.conf: Maximum Concurrent Jobs = 5
bacula-sd.conf: Maximum Concurrent Jobs = 20
include/bacula-dir-storage.conf: Maximum Concurrent Jobs = 5
include/bacula-dir-storage.conf: Maximum Concurrent Jobs = 5
include/bacula-dir-storage.conf: Maximum Concurrent Jobs = 5
include/bacula-dir-storage.conf: Maximum Concurrent Jobs = 5
include/bacula-dir-clients-linux.conf: Maximum Concurrent Jobs = 2
include/bacula-dir-clients-linux.conf: Maximum Concurrent Jobs = 2
include/bacula-dir-clients-linux.conf: Maximum Concurrent Jobs = 2
include/bacula-dir-clients-win.conf: Maximum Concurrent Jobs = 2
It looks like this is for the fd and the local sd and also some of the
client resources and storage resources in bacula-dir.conf as well as
the main bacula-dir.conf. BTW the include directory are files included
in bacula-dir.conf using the @ syntax.

With spooling, The answer is no. I limit my spool size to 2 to 5 G but
others limit it to much larger. I know Arno does uses a much larger
spool file that approximates the size of the tape.

Yes, I follow. I could go into more detail but this has been discussed
on the list dozens of times. Please check the archives for the pros
and cons of all of these methods...

You can use Maximum Volume Bytes = 250 G
instead. Or was that 25G? Much easier to tell with the G ...
