I always archive it so that we can recreate it. MB: So if you’re just need a backup and you just need to restore from your bootable backup, you actually don’t need it. MB: If you’re going to use the volume in production. As far as I’m concerned, the only reason you need a Recovery HD is if you’re going to use the volume in production. Now I say “need,” but you don’t actually need it. So if you have a volume with Mac OS X, you need a Recovery HD attached to each one. I just got a completely different perspective on it and realized that … well I don’t want to get into the weeds, but I thought it was kind of one Recovery HD per disk with Lion, but I think you actually need a Recovery HD attached to each installation of OS X. Indeed, Mountain Lion came along and it was like taking a square and turning it into a cube. It’s 100 percent sitting down and tearing it apart, figuring out how it works, and then making a guess about why it’s there, what it’s supposed to do, what Apple’s vision for it is, where it’s going to go. It’s not like a developer like me can go to /developer and hit the Recovery HD link and see exactly how the Recovery HD works, how big it is, what’s on it, how you bless it. And I don’t just mean that you can’t see the partition, I mean that it’s not documented whatsoever. And the reason for the misunderstanding is because it is hidden. There’s a lot of misunderstanding about this. Of course when you clone a drive, if you don’t clone that with it, you actually lose some functionality. TMO: And clearly Lion added a whole other layer of complexity to that by, in some ways hiding the recovery partition out there. It’s my job to cover up as much of that as possible and make the task that we’re trying to achieve, you know, cloning one disk to another that happens to contain Mac OS X and make it work as seamlessly as possible. There’s certainly a lot of nice things that are coming along, some conveniences, but there’s a lot more complexity. And if you look at Xcode lately, it’s the same kind of thing. I think Apple is hiring an army of engineers with the specific purpose of making it more complicated. Lately, especially Mac OS X, it’s has gotten a lot more complicated. That has certainly evolved over the years. And then I just wrapped an application around that. So I sat down and I figured out what the method had to be to copy the right stuff to make the right tweaks and things like that. People just didn’t believe you could do it. There was such a paradigm about how Mac OS 9 works and this mythology about how the UNIX underside of Mac OS X worked. When the Unix underpinnings of Mac OS X came out, there was some mythology about whether or not you could even copy Mac OS X. The way we did that in education, we couldn’t adopt it unless there was a way to mass deploy it. And Mac OS X had just come out, and I wanted a way to foster adoption of Mac OS X. Honestly, for most of the stuff that I’ve developed, it’s just been because I wanted it or my wife wanted it, and I just sat down and started writing it.Ĭarbon Copy Cloner was a little bit different because I was actually working at a university at the time that I developed it. It’s been at least a couple of dozen over the years, and most of them are just small utilities. These are just some of the popular ones.Īnd then there are others that I don’t even remember. Way back in the day, I did things like Share My Desktop, Stream Catcher, DeLocalizer. I’ve certainly developed a lot of other applications in the interim. Mike Bombich: Yes, I’ve been working on CCC for ten years. But you’ve had an interesting history with Apple that goes back further than that. You have been developing essentially one app in your app developer role for many, many years, and that’s Carbon Copy Cloner. This interview includes some intriguing, little known facts about that app.ĭave Hamilton: I’m here with Mike Bombich of Bombich Software, Inc. A short respite breathed new life into his work with his quintessential OS X copy and backup tool, CCC. Bombich left Apple two years ago to pursue his passion for being a creator of something great. At WWDC, TMO’s Dave Hamilton met with Mike Bombich, author of Carbon Copy Cloner for OS X.
