Hi Pablo, thanks for your help. When I got back into work, I checked again and there is no python3 on my RaspiShake and I couldn’t install it using apt, so I downloaded dropbox_uploader.sh instead, a BASH script, from GitHub - https://github.com/andreafabrizi/Dropbox-Uploader. The instructions are very clear and by putting an entry into the crontab, I am able to back up to a specific folder in DropBox every 15 minutes. I have now tested this from home and it is working, so I am happy and hopefully won’t lose several days data again as I did two weeks ago when my Shake lost contact with the server. Best wishes, Mark
