Jonathan noted that Apple will announce this week that the ZFS file system from OpenSolaris will become Apple’s new default file system. So how does that help Sun? It is pretty simple, now every Apple developer will know ZFS and how to use it on products like our SunFire x4500 storage server and other Sun products.
That’s pretty much unequivocal.
BWAHAHAHAHA! :bow: :devil: :bow: :devil: :bow:

This is awesome in ways I can't describe. It's not that there's anything ... "competitionally deficient" with HFS+, it's just not significantly better than NTFS. And both of them have major flaws that all major file systems share - for example, both of them don't do ridiculous integrity-checking of your hard drive's data. Which should basically be a mandatory feature these days, because no normal person backs up, and because anyone who uses a computer in-depth basically has their _life_ on there.

ZFS is ... an insanely good file system: http://en.wikipedia.org/wiki/ZFS

At least it's almost certain that the filesystem itself will be in 10.5, even if it's not the default (the filesystem has been present and functional in developer seeds of the OS for some months now).

ZFS and Time Machine just scream to be coupled together.

After reading that wiki article, ZFS seems like a lot of overkill (for the average user anyway). Exabytes? Petabytes? :eyespin:

And what's Time Machine?

Time machine is a "killer app". Time machine is a full-featured backup solution built into the os, but a whole lot more. Time machine is insanely well automated - all you strictly need to do is plug in an external hard drive, and time machine will (after asking you if you want to use it as a backup) automagically back up everything.

But Time Machine also doubles as an temporally-based unerase - if you have an item that "was in this folder last week", but it ain't there now, you can enter the fourth dimension, sneak back a week into the past, and copy the file that was there then into the present. Works for deleted files, works for moved files, and the OS actually supports it, so you don't have to hope that Norton correctly pieces the data back together; it's guaranteed to work, so long as there's space. And it'll actually try and do that with nothing to backup to except your primary drive, but for obvious reasons, if your drive is mostly full, it won't be able to back much up.



Part of what's so sweet about this is that a] and it's just at the perfect level of being "assertive about its presence" that everyone who is able to use it well (e.g. has a 2nd drive), will use it . And furthermore, b] it's part of the OS, and completely free, so .. everyone who gets 10.5 will have access to it. Unlike most other backup software, which, according to Generalissimo Steve Jobs, is purchased by a whopping 4% of the computer-using world at large.

Because let's be honest with ourselves - those rare few of us, like, who do actually back stuff up, don't do it very often. :uhoh:
