The long-awaited (at least by me) Leopard compatible version was released in the form of SuperDuper 2.5. Prior to Leopard SuperDuper was a critical part of my backup plan.
I haven’t installed the new version yet and since backups require a little more testing beyond just installing the app and making sure it runs, it may be a several days before I switch over to it completely. But it’s nice to see it finally released. The tribulations of getting Leopard & Time Machine compatibility were covered on the Shirt Pocket blog, although it is down as I post this. But the website is up and the software can be downloaded.
It’s a free upgrade to current users. There’s also a free version which provides the basic cloning features without expiration.
