Yes, well.. there is a possibility, but it's quite unlikely that Nagios will
execute the check while backup is running (and will not see previous backup
completed successfully). I myself have defined the period as 27-hours, for the
same reasons.
And anyway, even if Nagios will execute the check 5 minutes after the backup
has began, it will see the previous backup within 24-hours period, because
it's likely that the previous backup lasted more than 5 minutes (as does the
current one), and so was completed not more than 24 hours ago.
But even if the checks play out in an unlikely way, ONLY CRITICAL will be
seen, because the plugin checks the number of successful jobs (but none of
them will appear in this case), not the number of failed jobs.
PS. The check_bacula.pl script is not uploaded in the wiki, because my user
doesn't appear to have sufficient rights for that. I'll see where I can put it
:)
