Thinking Different: Time Machine
Tuesday, August 8th, 2006Watching yesterday’s Steve Jobs keynote at WWDC, the thing that really surprised me was Time Machine. Where has this been all my life? I am curious about some of the tech details. For instance, does it store diffs like CVS or only entire files? How do I securely delete something? Can I exclude large files I don’t want to back up to save space? (Update: Yes.) Can I specify redundant backups across multiple hard drives and network connections? Are the backups compressed? Can you backup to removable media? Is a .Mac subscription required? Will this backup system files or just home directories? (Update: Yes.) Will it create bootable backups? Do different file types require custom support, as with .Mac Sync? Can I back up network clients too? But overall these are only things a geek would think of and half of them only a geek would care about.
I wasn’t so impressed when I just heard about Time Machine, but when I actually saw it I was astonished. What surprised me was the user interface. This is decades beyond any other backup program I’ve ever seen. Once again, Apple threw out conventional thinking and designed something that’s actually easy to use. I don’t think other backup programs have changed in any significant way in the last 15 years. Why is only Apple able to think of things like this?
