veritas netbackup temp folder deleting script

Hello all. I am currently running into an issue with one of my server's disk space everytime i reboot. The folder NBU_VSP_cache fills up as much as 5gig and the drives are small so i need to run a startup script to delete it everytime i reboot the server. I am not good at writing scripts and not sure where to start. I was wondering if anyone can help or can point me in the right direction. I use veritas netbackup fyi.
