Hello,

This is a mini-status report just to let you know that someone on one of
these lists said that the new white papers advise using:

  Maximum Concurrent Jobs = 1

In the bacula-sd.conf Device resource.  I have reviewed the three white
papers listed on the bacula.org site and I find no such mention.  Almost
all the examples use MaximumConcurrentJobs=5 and several set it to 10.

If someone can point me to the place (if it exists) where 1 in
mentioned, I will be happy to fix it.

In addition, another person pointed out that manual_prune.pl does not
seem to be available. That was an oversight on my part, and that file is
now included as a download item under White Papers.  The essential
elements of what manual_prune.pl does has been integrated directly into
the Bacula source code, and in the next few days I will update the
documentation to refer to the new way of doing "manual" pruning (i.e.
pruning once a day rather than at the end of every Job).

For those of you who are not aware of the pruning issues, you need to
know that when one has many jobs (say 1000 per day) and many Volumes,
the normal Job pruning that Bacula does at the end of each Job can
become a performance problem (not likely with less than 50 jobs per
day).  To resolve it, it is best to turn off automatic pruning but then
to schedule an Admin job once a day that will do the equivalent.  The
program (now integrated into the code) manual_prune.pl was written by
Bacula Systems for the Enterprise customers, but is published for your
use with the community version.

Finally, I have made a few very minor changes to the Best Practices for
Disk Based Backup document.

Best regards,
Kern
