Backup of a dvd-r backup

Hi… just wondering if it is possible to make a backup of a dvd-r of mine that i have already backed up. I OWN the dvd, just want to know how to make a backup of the backup. I don’t think dvd x copy will let you do this. I have not tried any other programs.



Use dvd decryptor (free)
mode\iso\read then mode\iso\write…
