I also couldn’t think of anything that required no foresight, but I did discover that manually typing in Advanced options such as –log-file worked on step 2 “Encryption”, while step 1 “Backup location” choked on that option. Not sure if that was a quoting bug, or a slap-on-the-hand for choosing inappropriate options for that screen…
Because this is already filed as a feature request, I’ll raise the question of whether the UI can make this nicer, because if databases are ruled out, logging to the plain old text file is the only alternative I know of to live log. Perhaps this could also be categorized as UX, because it’s kind of a letdown at what might be a critical time…
