I have run paper and e-logs and I'm on e-logs now with LS. My understanding is that you always carrier paper logs with you just for this type of situation. I have never had it happen, but if your e-log goes down you switch to paper until it is back up and going. I think he said that he had been on home time and had left out when his e-log went down. That shouldn't be that hard to recreate, but not knowing how long he was home etc. makes it hard to know for sure. Also, you can log into QualComm and get your logs yourself. I do that every month when I'm doing my end of month paperwork.
