That is correct - it's a one-way merge where you can choose which data to merge/extract.  Your suggestion makes sense, although I'm struggling with the wording, because you are in fact synchronizing your library to the backup file (it's just a one-way sync). I'm not sure if it makes sense to say "synchronize from backup" from a purely grammatical sense. Maybe the wording should be "synchronize with backup file" when I think about it... I didn't want to have completely different wording as it's under the same synchronization menu as the other sync types.
