2013/08/01 12:19:22 Failed to create file system for “backup:var/www/”: failed to get root: Get https://api.onedrive.com/v1.0/drive/root:/: x509: certificate has expired or is not yet valid
Your log message starts 2013 which probably means the date is wrong on your systems. Set it correct and the error will disappear I expect.
You can force rclone to carry on regardless with --no-check-certificate but you really shouldn’t have to!
It fix my problem. ia have not seen the date.
