Advanced scheduling

I have two backup drives, one offsite that I rotate weekly. I've been using SuperDuper for a little over a month and for the most part it's great. I didn't think I had a particularly strange setup, but the use of cron for SuperDuper's scheduling system is driving me up the wall

After futzing with 2 scheduled copies for the last month or so I've finally worked out that the only way to make this work is use 4 schedules. 2 primary backup jobs scheduled for most of the week, and another 2 that adjust for the differences between weekdays and the numbered weeks used by the crontab.


To give you an idea of what I'm doing, I backup at 11pm daily and swap drives on Friday. For March, my schedules are now:

Backup to drive 1 on the first and third weeks, except friday
Backup to drive 1 on the second and fourth weeks, only friday
Backup to drive 2 on the second and fourth weeks, except friday
Backup to drive 2 on the first and third weeks, only friday
(if you think about it in cron terms - this is the only way to make the first backup 1-6, 14-20, 28-31 and the second 7-13, 21-28).

I've had to set a calendar reminder to adjust these schedules on the first of each month, April will probably require a 50/50 split between the two because the 1st is a Tuesday.

Are there any plans for a better scheduler? As well as proper weekly schedules, I'd love a "start but wait for drive" option on my mum's laptop. She finds it a hassle to remember that her backup drive must be plugged in at a certain time otherwise SD complains and the backup doesn't happen.


[edit]Just noticed this post suggesting iCal for scheduling. I can possibly solve my scheduling woes with that, but it'd be better if SD could handle it for me [/edit]

There are plans for all sorts of things... when we get an opportunity to execute those plans, though, is hard to say.

That doesn't help me much

Is there a priority list of your plans or do you just pick features for the next release out of a hat?

Now that I've worked out how to adjust the schedules once a month instead of doing it every week, it probably won't bother me a whole lot. It's still annoying though and seems awfully arcane / outdated compared to the rest of the app.

It's not designed to be a complex scheduler, no question, and we're working within the constraints of what cron -- which is what's available in all the versions of OS X that we support -- provides.

Now that v2.5 is Tiger-and-later, we can investigate using alternate methods for scheduling, though.

Ah of course, I hadn't considered that. I've been using macs for years but only recently had one of my own, so I have no idea what life is like under the hood on older versions of OSX.

Thanks for letting me know

Limitations of scheduling

Hello,

I remember having asked about this when I first got my licence for SD (2.x then) so I want to bring it back up. I do understand the current limitations of programming time in your company (just looking at the forum is enough –, personally I experience no problems with SD 3!) but this should be addressed at a point in the not to far future I believe:

When missing a scheduled cloning job because the mac was not awake or could not wake due to necessary security reasons (asking for password on wake) that scheduled event is skipped rather than executed when it is possible again. This is, what Retrospect is doing by the way. I really think that ability would greatly enhance the usefulness of the program and assure happy customers who will more often now have a current backup available…


Please put this high on the list of things to add!!

Greetings,

Rolf
