Hi again.
I took up testing it again so here are my results. I tried the 2nd option as
I'm using Bacula 1.38.9, but I couldn't get 2 jobs to run into the same
directory simultaneously.
I set up a schedule that would start differential backup 2 minutes after full
backup (16:16 and 16:18) and that would override Storage. I checked "status
client" periodically during the full backup and I didn't see that the
differential job had started. Differential started, when full job eventually
finished (16:35).
Did I misconfigured something? Would you please assist me? :)
