While this was similar in explanation to the Ars 10.5 review [1], I thought that it was a useful discussion of how Time machine works, including some valid, and some not-so-valid critisms of the implementation. I'd love to see future versions take advantage of redundancy in files.. If I make a 1K change to a 1GB file, I'd love to only keep the change. As I understand, this would be prohibitivly slow under HFS, but should be possible under ZFS, which natively stores files as original + diff anyway.
