I have paper logbooks both for my paersonal hours and the aircraft log which I keep at home and two excel spreadsheets that I have created to provide an electronic equivalent which I carry with me on my iPad and which are backed up to the cloud.
Contrary to the experience of others posting on the other thread, I have been asked for both during a ramp check (in France) and thought it easier just to comply - my spreadsheets were accepted - rather than argue about whether I am obliged to carry either.
