    Hi RLeon,

    I think I have the answer for you, and it doesn't involve having to change the Start Windows, only the days you have selected.  We do something very similar to what you are trying to do, so here are our schedules showing the Include Days which is what you need to tweak (including screenshots):

    • Daily: Monday, Tuesday, Wednesday, Thursday, Saturday and Sunday (Note - NOT Friday)
    • Weekly: Every Friday except for the Last Friday of the month
    • Monthly: Last Friday of every month

    So, by doing this you have the daily/weekly/monthly backup running only on the day they they are supposed to, with no chance of two backups on the same day.  One other important thing to note is that we do an "Accelerator forced rescan" on the Monthly backup.  This is recommended in the doco.  It basically reset your CBT, and does a full re-read of all the data, not just skipping over what it already knows about - so it will make the Monthly backup run a bit longer but worth doing and the Monthly is the perfect time to do it.  This is on the Attributes tab as shown below:

    Hope this helps,

    Steve

    why don't you use the "Exclude" tab for selecting days when a backup policy should not run?

    like for daily, exclude Fridays and month ends. for weekly, exclude month ends.

    but here's the trick, if their month end is on month end (not 1st of every month), they could use the "Include" tab to specify month ends only to ensure month ends runs on month ends.

    Thank you both for your suggestions.

    Systems_Team:
    Your suggestion on unticking Fridays in the Daily schedule solves the problem between it and the Weekly schedule. (Why didn't I think of that?)
    However, it does not solve the problem when the Monthly schedule is specified by DATE and not Day-of-the-week.
    Therefore, your solution works in your use case because your Monthely schedule is using the Day-of-the-week method.

    Our client specifically wants the 1st of every month to be the Monthly Schedule, regardless of which day of the week it is.
    So your example does not 100% work in our case.
    Any other suggestions?

        HI rino19ny,

        Thanks for your suggestion. The "exclude" method is a variant of same method that Systems_Team suggested. Essentially both methods give the same result.
        However, for the Monthly schedule, since the client wants a specific date-of-the-month, and not day-of-the-week (such as "last Friday of the month"), both yours and Systems_Team's methods do not solve our problem.
        I.e., sometimes 1st day is also a Friday, so it triggers both Monthly and Weekly schedules;
        sometimes it isn't, so it triggers both Monthly and Daily schedules.

        My brain is trapped in an infinite loop.
