As I understand it,the idea behind a spool file is to buffer the tape
device,so that the tape drive is kept in streaming mode as much as possible.
HJowever, my installation has this habit of deciding to buffer in 1.2Mb
chuncks, for a 44Gb backup,
This is a bit from the report

I have a 20gb spool file area defined in as below;
Device {
Name = Drive0
Media Type = DLT
Archive Device = /dev/nst0
Automatic Mount = Yes;
Always Open = Yes;
Random Acess = No;
Spool directory = /data1/bacula-spool-dir
Spool size = 20480000000
}
Is ths correct?
And should it befined anywhere else?
this is part of looking for cluebies to improve performance really.
somedays it all flies like the clappers and other days it struggles.
Basically 100Mb UTP through #com switch (aka good one0 and DLT does
about 5Mb/sec reported on Adapted 2940(scsi wide 68pin). The
boxen(debian sarge) really jst runs bacula and nfs to two linux boxen
and samba to two mswin boxen that do very little.
