Whatever you use, backup is essential! When I began studying for the PPL, my car was stolen out of the driveway! it was found next day in a well known Oxford estate, the car was OK, but the textbooks and MY LOGS had been thrown in a ditch somewhere! no value to the thief, obviously....
Ever since, I have PAPER COPIES MADE and kept in my house separately....the logbooks stay in the new car. which of course has prevented a recurrence....
