Wont let me backup iPod because not enough storage My iPod has not been backed up in six weeks. And I need 5 GB to back it up.  5 GB is my max storage. I don't want to have to delete everything i got to back it up. What do I do? Please help.
Backup your iPod to your computer rather than iCloud. iTunes will do that for you, see the "Back up using iTunes" section here

There are also third party tools that may help if iTunes fails. I used TouchCopy, and it worked well.
