i use ‘cp’. heck, i use ‘scp’… i just make sure i work in the window from 2 mins after archive interval (long after my archive updates are completed) to a few secs before next archive interval. could make BACKUP a new built-in report like FTP and RSYNC - unless want to make backup independent of weewx (e.g. scenario where restore is required because weewx is screwed up and stuffs up reports)
