I (user, not admin) have backuped data thru netbackup client (java gui) ,  now i want to delete the unwanted data that from the tape. How can i selectively remove data from the tape.

for example, delete particular dir, files,  or whole backup by backup_id

Is it allowed for ordinary user ?

I know, that admin can expire backup. But is there something for user to remove own backup(archive) ( like in Tivoli Storage M.) ?
