Yeah, we need more information. However, time machine browser might very well just be a fancy browser for a .zfs type setup, much like Solaris has. Just with GUI splash all over it. I'm just curious about the underlying implementation. I wonder if they did all this sticking with HFS+ or if they actually migrated to ZFS. The next weeks should be interesting as people get ahold of the dev copies.
