It is not clear what is your question is. Are you asking; how to backup a computer to a remote My Cloud?
If so the My Cloud does not officially have remote access capabilities other than those provided by; the WD Sync software, WD Desktop software, MyCloud.com web portal, and FTP. Smartware does NOT currently offer the capability to backup to a remote My Cloud. FTP is NOT a secure protocol.

You should read through one or more of those threads to gain an understanding of the unofficial methods one can use to try and backup their computer to a remote My Cloud.
