Re: [Veritas-bu] Frequency Based Schedules

Bob, that's what usually happens, but that's not why. The trump card is the retention level, which usually is matched to a longer frequency, but may not always be the case.

What are we doing Wrong?? You misunderstand how the (frequency-based) scheduler works. If the monthly and weekly schedules start at the same time, it will work as you expect. Assuming that you do both on, say, Friday night (I let mine float but that's another issue), you might set up: diff Sun-Sat, 2100-0600, freq 1 day full-wk Fri 2100-0600, freq 1 weeks full-mo Fri 2100-0600, freq 4 weeks The scheduler will find, obviously, only the diff to run at 9pm every day but Friday. On Friday night, the weekly will run because it is due (freq requirement has been met) and will trump the diff (yes, you could just skip putting the diff in but then you have two changes to make if you move the full to another day). Every four weeks, the scheduler will evaluate a due diff, a due weekly, and a due monthly, and the longest frequency will win--the monthly will run. It sounds as if you might have set your schedules up the way I do (on purpose), such as: diff Sun-Sat, 2100-0600, freq 1 day full-wk Sun-Sat, 2100-0600, freq 1 weeks full-mo Sun-Sat, 2100-0600, freq 4 weeks beause I don't care that fulls run on any day (there are enough to balance out through the week naturally), I don't care that on the first night the monthly runs, the next night the weekly runs, then six nights of diffs and a weekly..., that there will be a weekly within the same week (though not on the same night) as the monthly. If I run a manual weekly for some reason, it won't run again for a week after that. This logic is simple and, um, logical to me; calendar-based scheduling is _far_ too much work for me to manage... the midnight-split on calendar was so amateurishly implemented in 4.5... calendar-based just doesn't make sense to me except for the (IMO) *very* few requirements I have to back up X based on a business process that produces data in X on a certain date and has to be captured immediately and handled specially. This isn't meant to be an anti-calendar rant, just an illustration of the different ways of thinking about scheduling. > I know if we used Calendar based Schedules for the Monthlys > and excluded these dates from the Weeklys it would solve the > problem but surely there must be a better way. Thanks in advance... Don't mix calendar and frequency-based in the same class, though. I think there's still a statement to that effect in the admin guide vol 1--originally put there because, as I understand it, the freq and cal schedulers were (still are?) completely different processes and didn't share. _______________________________________________ Veritas-bu maillist - Veritas-bu AT mailman.eng.auburn DOT edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
