I confirm that in the terms and condition they discourage the use as a private cloud backup and only to host stuff related to the website. Now… until now I’ve had no complaints as I’ve been paying and kept the traffic at minimum. I guess I’ll have to switch to some more cloud oriented version if I keep expanding. But it’s worked for now !

A simple script using duplicity to FTP data on my private website with infinite storage. I can’t say if it’s good or not. It’s my first time doing it.

Sounds fun. But as others have said, plan a backup strategy like in the cloud or something.

If you don’t explicitly set a DNS to allow access from outside the local network, all your stuff is private and confined within your local network. As it is with all, let’s say, wifi stuff that goes on in your home.

Edit. What @notorious said
