How to exclude files and directories from NDMP backups

i need to exclude *.dbf, core, *.tmp ...

if you use NBU console it is so simple...

the doc is referring the class file list under the path \installpath\NetBackup\db\class

for every policy you create in activity moniter a class file will be created and it contains all the parameters set under policy with indiviual file names.

backup selection will be there with a file name "includes"; if you open that you can see what all you have provided in the backup selection tab.

to be very clear, if you update the backup selection tab; it will in turn updates the class folder in the backend.

For example:  To exclude a directory named /vol/vol1/A, but to dump the rest of the volume, create a NetBackup class file list which would look like this:
SET EXCLUDE = A
/vol/vol1

To exclude multiple files or directories use commas to delimit the field:
SET EXCLUDE = A,B,C
/vol/vol1

do i need to edit the include class file under policy name in \installpath\NetBackup\db\class and put the set exclude in that?

as per the tech note exclude it under your backup selection tab of policy, automatically it will update the include file under class folder

may i know where i can get the exclude file option (the client is a netapp storage)
