Configuring Backup Schedule in Netbackup 7.6
Hi,
I have a generic backup schedule query amd am hoping for some clarification/ assistance. Currently we have daily/ weekly and monthly schedules configure for different clients. When a monthly backup schedule is set, do we still need to exclude the weekly job frequency from running or is Netbackup smart enough to know that if a monthly job schedule is set to run tonight, it will not run the "weekly" job also?
I have attached several pics to illustrate my query.
Current Backup Policy Schedule
Weekly_Full Schedule (in Change Schedule window)
Weekly job excluded from the end of month backup (as per ticked box shown below).
Monthly_Full Schedule (in Change Schedule window)
Monthly job is scheduled to run on the 30th of the month (as per ticked box shown below).
Query: Do we need to manually "Exclude" the last week of the month (e.g. 30th & 31st), so that the weekly schedule job will not run at the same time as the monthly job for each month of the year, as this would be extremely tidious given the large number of backup policies that will need to be configured?
Any assistance is much appreciated.
Thanks and regards,
John
I'll chip in too... and I'm with Marianne on this... I've not had a problem mixing frequency and calendar schedules... (but once you understand how it works - you can see why some poeple say not to mix...) - but then I've only ever mixed them with straightforward scheduling - along the lines of frequency based for daily differentials, and calendar based for weekly (and/or) monthly full.
For example, if I have a 'backup window' of 10 hours each weekday night (Mon - Thu) of 20:00 to 06:00 next morning, then I set the frequency of the daily differential schedules to 11 hours. Which avoids schedule creep, and also means that if you manually re-run the differential schedule during the day, then it will still run 11 hours later - which may occur in the morning, but at least it will queue (and so should run).
And then have weekly calendar based full schedules, on 2nd/3rd/4th/last Friday of the month, to take a full from Friday 20:00, with a long 'backup window' until 06:00 Monday morning, with 'Retries allowed after runday'. And then monthly full schedule, same run window, retries allowed after runday, on the 1st Friday of the month.
I've never seen a config like this fail (since v5.1). Even if we have de-activated the policy on a Friday afternoon, to allow for scheduled maintenance on Saturday - and then re-activated the policy late on a Saturday - NetBackup takes the retries allowed after runday into account and still runs the correct weekly full or monthly full schedule.
However, with such a scenario, one would have to make it clear to the business that monthly full backups (long term retention - probably duplicated to tape) - are only taken on the first Friday of the month, i.e. after business month-end processes have completed.
But you can mix up the week numbers on the weekly and monthly schedules, e.g. I have also configured daily frequency schedules as above - but with weekly full on the 1st/2nd/3rd/4th and monthly full on the 'last' (for customers that wanted their monthly full in the last week of the month) - and never had a problem with that either - because NetBackup knows to run the least frequently run (an unfortunate term here - as, in this example, we're using calendar based not frequency based) schedule. i.e. NetBackup knows to run the monthly full on the 'last' Friday of a four week month because it hasn't been run for four weeks.
HTH.
