I turned off hard link support. Tried backing up and still seemed to have problems. Next I deleted the share to start the backups fresh. My laptop completely backed up 650 GB overnight. Great! Next I attempted to backup my desktop and it only backed up 240 GB in about twelve hours. Not so great but still better than before.
I've included a diagnostic file after backup was running all day.
