Well when you connect to a new network with Windows Vista not sure about Windows XP. You generally get a popup asking you what your location is your options are Home, Work or Public. Each carrying various permissions and options depending if your on a network you trust. For example if set to "Home" you can belong to a homegroup. Network discovery is turned on for home networks, which allows you to see other computers and devices on the network and allows other network users to see your computer.
Which in theory would still enable you to backup when on the home network as it is a trusted network. While at school I would recommend placing it on the "Public" option which will make it so nobody can see your computer on the network. Not to sure what to do with Windows XP.
