This is old information and no longer the case - https://shirtpocket.com/SuperDuper/SuperDuperDescription.htm...

I'm not sure your link disproves this article. The first paragraph just says bootable backups are supported (they are by CCC too), and the rest of the page hasn't been changed in years.

The SuperDuper blog says:

> Note that, as I indicated above, M1 Macs can't readily boot from external drives. There are things you can do, if you have an external Thunderbolt 3 drive (USB-C isn't sufficient), but even that won't work if the internal drive is dead. Unless things change, bootable backups are basically a thing of the past on M1-based Macs. [0]

in a January article, and I haven't seen anything that contradicts it in more recent articles. Mind linking?

(Note that booting from USB-C is now supported on AS Macs, but booting when the internal drive is dead is not)

The blog entry you're referencing is old. Please follow the link I had provided - https://shirtpocket.com/SuperDuper/SuperDuperDescription.htm... - note the recent version number and its respective description.

Again, bootable backups work fine on Apple Silicon, but not when the internal drive has failed, since booting requires an iBoot volume stored on the internal drive. I believe there's a misunderstanding, and SuperDuper hasn't found any workaround for this.

Though who knows what types of experimentation, trial and error SuperDuper went through to make it work.

I know that David Nanian and co worked with Apple to address the issue(s) that prevented them from providing a bootable backup.

The ability to create bootable backups on external drives as you describe, does not necessarily conflict with the inability to boot from external drives as the post link describes.
