Policies Didn't Start

Hi all,

I have encountered this a couple of times but not sure where to start looking.

2 backup policies completed their full backup over the weekend but the Cumulative jobs didn't start last night so I have no errors or anyting.

I guess it must have something to do with the scheduling?

I use Calendar based schedules, e.g. Cumulatives run Mon-Fri & Full run Sat-Sun.

Any pointers where to pin point this?

Thanks,

Mark

But not sure of your NB version, nor am I convinced that this would explain why your backups aren't running on a Monday - from what I can determine from this T/N it would be more liable to affect those on a Tuesday etc due to the schedules spanning midnight into the next schedules' day (unless that's not a specific requirement for this bug to manifest itself?)

I would suggest changing your policy to be frequency based - this would be just as workable as the set-up you're running:

e.g.

# bpplsched aiglies1 -U

Schedule:          Full
Type:            Full Backup

        Saturday   12:00:00 --> Sunday     15:00:00

Can you share the schedule from such a policy with us?

Also, take a look at this. Lots of comments about calendar based schedules not starting when they should

Start Window & start date seem fine to me.

Hi,

Having looked at your schedule I would suggest that you switch to frequency based scheduling. You're backing up FULL each Saturday and CINC Monday to Friday. Calender based is usually or most effectively used when you would like to backup on a specific date i.e. last friday of the month, always on the 27th, etc etc.

I'm not just saying this cause its easy to not dig deeper into the issue, but rather from years of NetBackup experience. I'm also 100% sure that most users (trusted advisors) on the forum would agree with this.

It gets a little more complicated when your calender schedule span midnight because Netbackup treats that as two seperate windows, not continuous one.

If you really want to get to the bottom of it you can look in the nbpem log to see what/why its is not starting the jobs when expected.

I would go for frequency based though. Keep this post open and see what the rest say!!

..Thanks Guys.

I will look into your suggestion.

I have another site with 1 Master Server & 20+ Policies where this has happened once before so I'm gonna have my work cut out to change all these.
