This within the NewVolume() section got close enough to what I want:
from time import localtime, strftime
rightnow = strftime("%Y%m%d%a%H%M%S", localtime())
thisjob = "%05d" % jobid
job.VolumeName = "%s-%s-%s" % (client, thisjob, rightnow)
I end up with volume names like cas-test-fd-00286-20071205Wed000436
where cas-test-fd is the client, 00286 is the five digit zero padded
version of the job id and 20071205Wed000436 is the
YearMonthDayDayofweekHourMinuteSecond.
So they should sort in a file list like I wanted until I hit 10
jobs which will be many years in my case, and won't conflict unless the
same job can write 5 GB to one volume in less than 1 s and thus need to
create a new volume in the same second as the previous.

well, bad news for you. python seems to be the one who will go away.
labelformat variable expansion also is supposed to disappear at some
point, but in the end it was suggested to simply use labelformat for now
and deal with any potential changes in future.

currently i am using the following labelformat value :
Label Format =
"${Pool}_${Job}-${Level}-${Year}.${Month:p/2/0/r}.${Day:p/2/0/r}-${Hour:p/2/0/r}.${Minute:p/2/0/r}"
it should be possible to get out of it and bacula manual the desired
format for you.

[Bacula-users] auto labeling with python
I'm using Bacula 2.2.5 and have tried auto labeling with LabelFormat but haven't had much luck. I don't know python but since LabelFormat is deprecated I thought I'd go ahead and give it a try. My goal is to get volume names ( and the corresponding file name on disk, I'm backing up to disk ) to be formatted like jobname-date-"two digit number of volumes for this job". I've also set the max volume size to 5 GB. So if I had a job named sivadaily run at 0300 and backup 9 GB I would like the resulting two volumes to be sivadaily-20071130fr0300-01 and sivadaily-20071130fr0300-02. I started with the sample director startup script and the documentation at http://www.bacula.org/dev-manual/Python_Scripting.html#SECTION00356. I defined "jobname = job.JobName" and modified job.VolumeName in NewVolume() to be 'job.VolumeName="%s-%d" % (jobname, numvol)'. Then I ran a test job, cas-testdaily, and got volume autolabeled as 'Labeled new Volume "jobname-44"'. So I guess definition of jobname didn't work. Also, I'm assuming the %s and %d are for string variable and integer variable although a bit of googling and python manual reading hasn't verified that. Any suggestions for how to accomplish what I'm after and recommendations for learning the python basics demonstrated in the sample script?
