Netbackup Cumulative Incremetnal Backup of File server folders are not working

[demo4119]

Configuration:----

netbackup master 7.01

MS cluster 2003 Enteprise SP1 running Netbackup Client 7.01

Currently i have policies for Daily Cumulative backup and Weekly Full backup.

But when i checked the Daily cumulative it backup the same no of folders and files as the weekly .

I ever manual run a full backup and then rerun a cumulative but still the same ( huge)

Where could went wrong as i never faced this issue before.

Can you confirm - are they different policies? Or do you mean schedules within the same policy?

For incremental schedules to work they must be in the same policy as the Full schedule.

[demo4119]

schedules are on the same policy .

Is this link to a similiar to the problem identified on Netbackup 7.0.1 and solution was a engineering hotfix?

My issue is use netbackup agent based backup .

did you check the data size in the daily Cumulative Incremetnal Backup  and Weely full..

is that data size is also same.in both incr and full backups?

did you check the file modifiy time.? they may modify every day..

switch from archive bit to time stamp

what is the -dt flag in the bpbkar set to? Does it say -dt 0 ?

[demo4119]

How to check the -dt flag?

I have changed from archive bit to timestamp but still the same .

I found that the weekly policy for those issue backup is not running every weekend.

So i have manually deleted all the problematic policies and recreate it . Then run a bpdown and bpup on the master server.

And last weekend backup is running fine . I will need to monitor the cumulative incremental for tonight.

Thanks guys for your keen input.

Setup logging for bpbkar on the client. The -dt flag is in the first couple of lines....

lpCmdLine = '-r 604800 -ru root -dt 0 -to 0 -clnt serverA -class serverA_DATA

[pikachu]

-dt 0 means it ran as a FULL backup.

[ankurkumar]

whats the type of backup you're doing, File system or Database

Did you see this in the title of the post?

"...Backup of File server folders ..."

Problem solved . after delete and recreate those policies .

The problem started because the some policies didnt run on weekly Full so it caused the daily to run as full backup ever i have manual change those daily to full for once and then change back to cumulative incremental.

Dont know why.
