Actually yes, right you are, that's not a solution. Especially as the "Max
Wait Time" causes the running backups to be cancelled after the specified
time (I complained about this in a separate thread).
Right now it came to me that the same check could be done with "run before
job" script. A quick example (check-job.sh):
=====
jobName="$1"
jobId="$2"
if ( echo "status dir" | bconsole | grep -v "${jobId}" | grep "Job
${jobName}.* is running" ); then
exit 1
else
exit 0
fi
=====
The script should be ran with "Run Before Job = check-job.sh '%n' '%i'".
Some notes after testing that solution:
* the same job must be able to run concurrently, because "run before job" is
executed before starting backup, not when the job is scheduled
* user of bacula-dir (running process) must be able to access bconsole.conf
* the "Run Before Job" may be used next to other "run script" directives
Any thoughts on that approach?
