Data integrity question- how much verification by SuperDuper?

[dnanian]

We're very conservative about error handling. If we get back any errors at all during the process, we stop and log the file (as well as a bunch of information about it).

Of course, if the directory damage involves the tree we're walking -- and leaves files out -- there's no way for us to know what's not shown to us by the OS...

What specific errors is SPX running into here? A comparison error, or an inability to walk the tree?

The SPX error: "* An error occurred while getting the location of the parent directory of a file to be written. Current privileges do not allow the operation."

This error appears during a verify-only, so nothing is to be written. I'm not sure if it is a typo in error message or a revelation of some hack or low-level error in getting data for verification purposes.

SPX has its share of bugs and I'm not very happy with it... it's another motivation for this thread- just seeking better solutions.

That's unusual. I have no idea what they're trying to do there...

Right. But, as a user, that and other problems are what I want to detect and know about (as I'm sure you understand)!
