If this has happened again, I'd suspect corrupt data on your phone, that of course gets transferred to your backup when such is created, thus preventing you from updating that backup. Your only choice to get out of this cycle would be to again delete all existing backups, then restore your phone as a new device in itunes, followed by syncing your itunes content back to your phone. When prompted to create a backup before restoring as new, decline. This will erase all data on your phone.
