Restoring Snapshots from Dropbox


I'm confused about Snapshot. The documentation says that if an external location like Dropbox is used, backups are saved there instead of locally. But, when I look at backups I've done to Dropbox, the files appear to be downloadable locally (from the web server). Am I missing something?

And if you restore one of these backups, is it actually restored from Dropbox? Or is there a local copy, or is it copied back to the web server and then restored?
