backup esxi to google disk or dropbox

hi all,

sorry for possibly repeating question, but maybe someone have done backup to dropbox or doodle drive using esxi script or Linux machine?

Or I will need to have windows machine with esxi-cli and powershell?

maybe someone has some sample script for the same or some backup?

Thank you for a help or some link to material.

P.S. I do not want to use some third party like (http://www.cloudbacko.com/vmware-esxi-backup.jsp https://www.ahsay.com/jsp/en/home/index.jsp)
