Just looking for some general advice. I bought 2 x 3TB WdMyCloud’s, intending to use one as a backup for the other. I have about 2TB worth of data. I have tried using the built-in WDMyCloud backup via the web interface, and it starts out OK but after a day or two it keeps restarting and never finishes.
I have tried using 3rd-party utilities like Carbon Copy Cloner and I have the same problem. I gather that even with 100Mb ethernet, backing up from NAS to NAS is inefficient. But I can’t see a way to do this over USB, because the WdMyCloud only supports USB to go *out* to a backup drve, you can’t access the drive any other way than over ethernet.
So my question is, is it even possible to use WdMyCloud to back up WdMyCloud (with 2TB of data)? Or is it a pipe dream?
