Pro series EX4100 and Pr 4100

The wd models ex4100 and pr4100 only receive data when they are connected if the equipment is turned off it is not possible to access the cloud and upload files ie aa wd does not allow files to be placed in the cloud and then when the equipment is switched on To Nas Why?
I appreciate information about this subject.
Thank you


The files that you upload to a My Cloud device go to the NAS itself, not to a WD Server. Therefore, if the devices are turned off, they’ll be offline for cloud access.

Thanks for the reply, it is regrettable that this is so.
If we have an account on another server, will we never have access? Or just with Elephamt Drive or Dropbox account
