Several services have come up that strive to provide this ideal in a subscription based model. Additional benefit is that in exchange of this subscription, you do not have to invest in anything extra, not a single disk or media even. All you need is an internet connection. Depending on the type of service, it may need to be a always on connection. The ones that are not always on, usually need some user intervention. By storing data on a remote machine, possibly a remote data center, additional benefits you derive are that the data is available from anywhere in the world. If you travel a lot, this a convenience which is quite useful. Variations in services are many but fall in a few broad classes. The first type is you download a batch uploader from the service provider and keep uploading your files. You can usually have on-line access and manage the organization of the files/folders. Come time for a restore, for whatever reason, you can simply download a specific files or the whole lot, if required. Similar features, but through the browser access, is another variation on the theme. A particularly convenient form is the services just require an Internet connection, whenever there is a connection on, it will do a back up of the identified files. An interface is provided for restore. This is truly hands-free service. Once set up there is nothing that a user needs to do.
