Backup between two WD MyBook?

Hello! I’m trying to set up the backup in WD Smartware so that the contents of my MyBook get backed up on my other MyBook, but the software doesn’t seem to collaborate, since it won’t let me choose an external drive as backup source… Ideas? Thanks for the help!


It wont do that automatically… you can select the source of the backup but the software wont duplicate what you put on the first one to the second one.
