Automated Backup Up Across Internet?

Hello, I looked through the stuff I could find online but not finding what I need. Could someone direct me to some documentation or a video that tells me how I can set up backups from laptops TO my PR 4100 that

a) are automated.
b) can happen across Internet.
c) only allows the user to see their own backup share. No other shares visible.

Thanks.

Hello,

The My Cloud PR4100 comes with two applications WD Sync and WD Smartware.

WD Smartware is a backup software that facilitates automatic and continuous backup of all your files within the network. Not remotely through the internet.

WD Sync is a utility that allows you to sync your files to the My Cloud device either locally or remotely. You can also configure the user permission so the users will only access their own shared folder:
