I have purchased 2 My Cloud Mirrors, one for the office and the other for home to backup remotely. I currently have existing data on an old My Book World (about 1tb) which I will copy onto the office My Cloud Mirror, and in turn this will be backed up on the home My Cloud Mirror.
To avoid initially backing up 1tb of data over the internet, can I begin the back-up locally before physically relocating the second My Cloud Mirror to home and then continue the back-up remotely?
