NILFS is, by default, a filesystem that only ever appends until you garbage collect the tail. It doesn't really "snapshot" in the way that ZFS or btrfs do, because you can just walk the entire history of the filesystem until you run out of history. The snapshots are just bookmarks of a consistent state.
