Just bought the home duo and im happy about it.
Im not so happy to find out that WD Backup doesnt support MCH products.
I have been looking around and found the SyncBackFree backup software and it works excellent.
AND IT IS FREE ! - for private use (free edition doesnt run on servers).
@FlemmingA, Please refer to the link for My Cloud Home Backup: My Cloud Home: Backup a Windows or macOS Computer
Thank you.
But SyncBackFree works perfectly and is much easier to set up
