Count me with the folks that know backups are vital and just don’t do it because it’s too much effort. If Dragonfly could implement Time Machine using the new HAMMER filesystem, that would be a real feather in the cap. I understand that Leopard has low-level hooks for Time Machine which is why Flyback and Time Vault will never work as well, they have to rely on the rsync method of scanning everything. I think Time Machine is helping Mac sales a lot, and that identical (and equally easy to use) functionality should migrate to all major OS. It appears that Dragonfly could get a jump on the rest if HAMMER already or could easily support it.
