I just restored my phone, restored to my last backup. Everything installed and I tried backing up again and it worked. Thank you everyone.

After getting a new PC and reinstaling iTunes, I'd been receiving this alert when trying to backup/sync my iPhone4, but none with iPad using the same cable and environment. What solved my problem was setting the iPhone to airplane mode. I guess it was something related to sync over wi-fi (that was disabled on both devices, but was somehow causing these issues).

In aircraft mode, the back ups worked fine
