This problem, I think is the frequent situation that you may come across when using iTunes. So how to stop the backup on iTunes ? Here are two ways here.

The first way is just about how to cancel the backup when syncing your iPhone with iTunes. During the process, you may experience freezing, stalls, data loss etc.

A fabulous software called O2Tunes will do you a favor with no anxiety! With it, you can back up the files at your will and also stop the backup manually.
