Default [Q] Backup But... Help?

I'm rooted but none of my backup managers will let me make a backup of my app's to external sd card... I'm trying to backup so I can try a new rom, but also everytime I try to copy or delete something from my external sd card it says it failed or denied and card is something I forgot copywrite protected or some crazy junk like that.

I just wanna get control of my external sd card back
