Hi Uwe,
I'm using mixed priorities because i want to handle the case in which all
job slots are occupied.
For example, if there are only a free slot i'd like to assign it to a more
important job (like mailboxes) instead of a not critical job (like server
configurations).
Are you suggesting that, because of bacula behavior, i should increment the
number of slots instead of assign priorities to the critical jobs?
I don't like very much this solution... a lot of job will eat my bandwidth
slowing every job scheduled in that time, included the critical ones that
should be completed as fast as possible!
That's exactly what i want to avoid.
Thank you again.
