I've been having this problem for the last month as of today. My last backup is stated as August 16, 2012 (before I cleared all iPhone backups). I really would like to still be able to keep all of my previous data, should something go wrong with my iPhone 4S, or whenever I upgrade to the iPhone 5 in about 2 weeks to a month from today.
It all started when I removed about 1.5K photos from my camera roll, I noticed the problem while trying to sync my iPhone, and it was stuck on step 2 of 7, which is, backing up.
I've tried these possible solutions already, all with no luck:
-Hard resets to the phone (several times)
-SMC reset on my iMac
-Reinstalling iTunes (rerunning the installer while iTunes still exists on the Mac)
-Cleared "/var/db/lockdown"
-Deleted ALL previous iPhone backups to the iMac
-Using a different admin account
It's basically stuck doing this, causing the phone to reboot SEVERAL times an hour.
To be more clear, I am using iTunes 10.6.3 (25), and OS X ML 10.8.1. Both totally up-to-date.
