You can set up rclone with Google Drive in an unattended mode, i.e. not tied to a specific end-user Google account. This is useful when you want to synchronise files onto machines that don’t have actively logged-in users, for example build machines.
I do want to sync some forum backup files from a remote host to a Google Drive belonging to a specially created Google user, so Service Accounts seems like the right option, but I'm having all sorts of issues, chief being that I can't see where the files end up.
If I were to obtain my own client ID, what exactly are the limitations for unattended syncs vs. Service Accounts? Do I need to log in with that user every X days?
