Backup to non-MyCloud NAS server

I use my MyCloud as my network storage device. On my LAN I have a Qnap TS-230 NAS server that I use for backups. I would like to backup my files on the MyCloud to this serevr.

What have you tried, if anything? Below is an example image of how I would copy from one My Cloud to another. The image shows I am copying from my WD MY CLOUD TWO to my WD MY CLOUD. I have Windows 10 Pro with all updates.

Click on, tap, or activate image to enlarge it.

If you want to sync/backup have you looked at the apps available for OS5?
