Does Superduper! use block level cloning and verification?
 

Like a few others probably, I am temporarily using Carbon Copy Cloner for Leopard volumes. One choice it offers which I have not been aware of before is "block level" or "file level" cloning. Block level is only available under certain limited circumstances, but I have the impression that it is preferable to file level when possible.

Also I notice CCC has a verification phase at the end of the clone.

I have used Superduper! since the beginning without problems, and much prefer the interface, but I am now curious as to whether Superduper! does block level and verification.

Thanks

We don't do block level copies, and prefer file level, so directory corruption is not copied (and is detected). It's not really "preferable" to file level -- after all, when you use your Mac, you're using it at file level -- it's just "faster" (except when running Smart Update, of course, because you can't really smart update blocks).

We don't do verification because your disk controller does it for you -- and your system is constantly changing, even while you're backing up, so the verification would always fail anyway.

Thanks for the explanation and clarification.

Before Superduper! I used Retrospect for making a bootable copy and as you say the verification produced a stack of errors for things which had changed during the clone. At least CCC only uses verification for a block level clone for which the source and destination have to be unmounted.

Looking forward to new Superduper! but fully support having it right.
