With as many people that have this same issue, I am very surprised that support is still sleeping at the wheel.  Some of the suggestions border on the absolute absurd (e.g. create new user account, check the system clock, etc.).  I've tried them all, including exclusion from AVAST, resetting router, etc etc etc.  iCloud status shows all green.
As the owner of a software development company, I find it hard to believe Apple, of all support, has been unable to get this issue resolved once and for all.  It would certainly make sense, as well, to collate this issue into a single thread instead of bouncing users off the moon and back.
I spent 1/2 day on the phone with Apple support trying to get iTunes to backup and was promised a call back from the next tier of support.  That was 4 months ago and I still haven't been able to backup my iphone 4S.  I've never seen software that is more kludgy and unreliable with every passing upgrade (sorry, but it's the truth)!
After two years of not being able to back up my phone, I am considering going to a more reliable platform.  After 6 years on the Apple bus, maybe it's time to get off.
