Time machine backup

I know that this has been covered before, but the answers haven’t helped me.
I have a Duo that appears on my desktop (Mac running Mojave) but it does not appear as an option under time machine preferences. I’ve rebooted everything etc. Any suggestions? Thanks.
PS. I’d also like to transfer files from my older WD Cloud and can’t find out how.

Hi hungry_otter13,

You can refer below article to get My Cloud Home under Mac Time Machine backup.

In order to copy data from My Cloud to My Cloud Home:

  1. Connect both in the network, then Drag and Drop via macOS finder
  2. Network Import service of the My Cloud Home to import content from a My Cloud

You can configure Network Import services from Services tab after logging in on mycloud.com for My Cloud Home device. It allows to import or copy data from older model My Cloud device into new My Cloud Home device.
