Using My Book Live as a Backup NAS on a different network (not the home network)

I want to place a My Book Live at my parents house (same country, different city) and use this My Book Live as a NAS. The My Book Live would be attached to a Router in my parents house.

Question:

Can I access the My Book Live over the internet from my home and use it as a Backup Storage/Cloud Storage (eg. Apple Time Machine)? I’m wondering if this works or if the My Book Life has to be necessarily in my own home network.

B/c of the fact I can access my already stored files remotely from a different place, I assume this also works as I wrote above?

WD2go lets you do what you describe.
