Alas, Jonathan Schwartz was wrong

With WWDC almost over, there has been no new of ZFS on Mac OSX Leopard.  But didn't Jonathan Schwartz say that was going to be the defaiult file system?  I even blogged about it here .  InformationWeek has been trying to reach anyone at Sun willing to comment, but they have not been able to locate a single person willing to go on record.

Apple has responded however.  Numerous times in fact.  First they said "absolutely not".  Then they said "maybe."

The final word seems to be that Apple will support ZFS in read-only mode.  They will continue to use the nearly 10 year old HFS+ as the file system of choice.  That is not such a bad thing.  I mean, it is tried and tested and has proven itself reliable.  Would I love to see ZFS?  Sure.  It is more appropriate for the Xserver environment however due to its large drive capacities.  I am starting to doubt the benefits for the normal MacBook or iMac user.

 But what about Time Machine?  It seems that Time Machine is nothing more than a backup solution.  Don't get me wrong.  It is still a great product.  But my entire thesis on how it could work is utterly wrong.

 Time machine works as a backup solution which til now has been sorely missing in Mac OSX.  There has been no efficient way of performing backups.  At least that is my experience.  But instead of having to run an application to backup information, it will run in the background.

Much as Vista asks you if you wish to use a USB memory device to augment the RAM in Windows, Time Machine will see any new hard drive and ask if you wish to use it as the backup device.  You can even connect a USB hard drive to an Air Port Extreme and use it for multiple machines.  As I understand it from the keynote given by Steve Jobs, the software will make an initial full backup of your entire system.  Every time a file is modified, deleted or added, Time Machine will move a copy to the archive location.  This enables you to go back in time to a period when the file existed in the state that you wish to retrieve.

 This might be a little bit slow, but if you are using the full 802.11n pre-release spec that the Air Port Extreme provides (as well as the newer Macs), this is nothing.  Since it is done in the background without any user intervention, there should be no performance lags caused by the software.

Add the slick Core Animation features and you have yourself one hell of a decent backup solution.  It is worth the $129 price of the upgrade all on its own.   But youget even more features in the new OS.  I will be waiting in line with cash in hand.
