Hi,
I currently maintain a number of small bacula installations for
organizations that only use a single tape drive and do full backups
every week night. One issue that cause some grief is holidays - there
is no one around to change the tape and the situation is not handled as
elegantly as I would like.
I did some research and stumbled upon the following python script that
does exactly what I want: the script checks a text file with a simple
holiday schedule entered in a month/day format and will return 0 or 1
upon execution.
http://www.biostat.wisc.edu/~annis/creations/period.py.html
I tried a simple RunBeforeJob with the script itself - after fudging the
holiday file to make today look like a holiday. The script returned a 1
- - as it should - but the job continued running. I thought that if a 0
is not returned from a script then the director would abort executing
the job - exactly what I want for my single tape drive environment.
More important than the text returned is the status code the script
exits with.
Try using sys.exit(1) instead of simply writing the "1" and things
should work... at least, using a bash script, I can prevent jobs from
running.
Here is the relevant bits from my bacula-dir.conf:
Job {
Name = "TESTER"
Type = Backup
RunBeforeJob = "/etc/bacula/period.py"
That script would be very useful to see...
Client = testlet-fd
FileSet = "Full Set"
Schedule = "WeeklyCycle"
Storage = DDS-3
Messages = Standard
Pool = Default
Write Bootstrap = "/var/bacula/NightlySave.bsr"
Max Start Delay = 22h
}
and from the log:
06-Mar 09:51 testlet-dir: No prior Full backup Job record found.
06-Mar 09:51 testlet-dir: No prior or suitable Full backup found. Doing
FULL backup.
06-Mar 09:51 testlet-dir: RunBefore: 1
... and here, some message like
"04-Mar 08:20 goblin-dir: DracheStd.2006-03-04_08.20.00 Fatal error:
RunBeforeJob error: ERR=Child exited with code 1" should be reported.
06-Mar 09:51 testlet-dir: Start Backup JobId 6,
Job=TESTER.2006-03-06_09.51.28
06-Mar 09:51 testlet-sd: Job TESTER.2006-03-06_09.51.28 waiting. Cannot
find any appendable volumes.
Please use the "label" command to create a new Volume for:
Storage: "DDS-3" (/dev/nst0)
Media type: DDS-3
Pool: Default
The RunBefore returns a 1 - but the job progresses.
I am sure there is a much more elegant way to integrate this python
script into the new bacula python framework - but i am certainly not the
guy to try that ... :)
Any thoughts on the best way to do this is greatly appreciated.
One simple line of code should be enough... perhaps two, if you also
count the "import sys"...
