If you are looking at the single bay My Cloud then you should really take some time to read the My Cloud User Manual (http://www.wdc.com/wdproducts/library/?id=439&type=25) to gain an understanding of the features (and limitations) of the device.
The older v4.x first gen single bay My Cloud units do not have any kind of official backup to a remote location capability. The newer v2.x second gen single by My Cloud units apparently do have a limited capability to backup the My Cloud to a remote location that typically would contain another second gen v2.x single bay My Cloud. See Chapter 10 Managing Backups, Creating a Remote Backup where this feature is discussed.
Unofficially and absolutely not supported by WD and which may violate the single bay My Cloud warranty one could use SSH to install the GoodSync for WD My Cloud service/module that may sync to a limited number of online storage services. Unknown if the GoodSync works for both versions of the single bay My Cloud versions or just the older v4.x version.
