Will Time Machine work effectively with a WD MyCloud NAS device?
I've had the same issues as Evert. I have now given up and pulled the plug on my WD My Cloud. Although I have seen that some people are getting on okay with it, most of what I have read concurs with my own finding. It is no good as a time machine back up. It is terribly slow. My last successful back up, which added approx 250gb to my already backed up 1.25tb took 7 days. Prior to the verification messages now encountered I would wait a day or two to get passed the 'Preparing data' message. I can no longer even access the wd my drive as a timemachine and it no longer recognises the info, even though the amount of space on the WD cloud drive indicates the backed up info is still on there.
I am converting back to a usb external hard drive.
I would recommend buying anything rather than the WD MyCloud if using it with a MAC.
