    So,the quick anwer is : 
    No. NetBackup does not have Incremental forever like TSM.

    Dedupe won't work either because compressed files do not dedupe well. 

    All I can suggest is that you change the backup selection from time to time to remove old folders that do not need to be backed up again.
    Maybe once a month - e.g. for Oct you will have 2018/10/* with a full backup on the 1st, followed by incrementals for the rest of the month.
    Or else, update exclude list before next Full is due. 

    I realize that this requires manual intervention and discipline to update policies, but it could be scripted and added to an external or OS scheduler (like cron).

    Another option would be to invest in an archiving solution for these zip-files.
