If you could find a way to do it, remotely backing up the drive over the internet would recquire great upload speed at their office and good download speed at their home and most lilely take a real long time when that drive starts filling up. I am not even sure what software would be able to do that on a My Book Live to My Book Live over internet.

That post shows WD STAFF stating that it cant be done;
"
Hello,
Currently, the MBL will allow you to create the Safepoint within the same network. Not on a remote address.
Please note that is always recommended to keep at least two versions of your files in case that one fails. That’s the real meaning of a backup."
