Z. Oracle. The log files were cleared down after being backed up, usually multiple times for belt & braces safety. The log file space was then available for re-use. Oracle is just a bunch of os files so was generally backed up with an os backup utility along with the rest of the backup (though occasional enlightened customers would allow us to use Rman). So if the backup failed, log files were not cleared, the space fills up and ultimately our "running out of space" monitor would trigger.
The guys were not happy at being pulled out of bed for someone elses failure. I could tell some horror stories but I'd rather they kept funding my pension :-)
