After carefully watching the backup progress for several hours in bconsole, I
gradually started to understand how its status is reported.
The "Running Jobs" Files, Bytes, AveBytes/sec, and LastBytes/sec track
spooling process only. These counters stop as soon as the spooling to disk is
completed. They do *not* track despooling at all. Despooling to tape is only
tracked under corresponding Device sections.
This still leaves open the question of why despooling is suddenly so slow
after the Bacula upgrade...
