I’ve started using Google Drive to backup my database. For a given week, it works as I would expect it. After a week, the backups stop being executed, and no logs are generated. It seems like the auth token is only lasting a week, and the system (Frappe/ERPNext) does not seem to know how to do a “refresh token” to keep it working.
Can this be verified, and if so, I’ll file an issue on GitHub.
