Hi …newbie non technical guy here…
I have tried to copy my External HD to google drive but as I understand there needs to be some space on the computer drive for it to do that. Anyhow it didnt work. As a result of my research I found syncthing.
My question is can I use syncthing to first upload to google drive and then like on weekly basis plug the HD in to sync the changes to Google drive as a backup.
