OTOH, there are clever tricks you can play to reduce this. For instance, hash all every file before uploading, and if the server has seen that hash before (from another user, or from a previous run by the same user), the server just adds the to your collection of files available to restore--no second upload required. Yes, if you're the first person to backup a new version of Windows or a new movie torrent, your upload time is going to suck, but on average, the time to upload each new file will be close to zero.
