I have a user who has not been able get a complete Time Machine backup since he upgraded to Mountain Lion. He is backing up to an external USB hard drive. We even replaced the external drive with a new one and reformatted it (Mac OS Extended Journaled). What happens is that when starting the first backup, it shows as "preparing for backup" under the TM status windows and "cleaning" on a popup status. After about 20-30 minuutes, the backup starts. The system slows down to a crawl. There is about 271 GB to backup. It will run for a few hours then fail. The error is attached. I've been on the phone with Apple Care and they suggested what we already did - try a different drive, format as Mac OS Journaled, etc. Is there a log file that I can look at to see why it is failing? Any other suggestions?
