Well, you should have logs shouldn't you? I found this, which pretty much sums up what I remember:

create a log file with:

/on:filename.log or /oa:filename.log

The first creates a new log, the second appends to an existing log.
By default, the log file will contain the names of any files which
failed to be copied. You can also fine tune the contents in the log
file with /oD<n>, /oE<n>, /oF<n>, /oI<n>, /oP<n>, /oS<n>, /oX<n>. See
xxcopy /o/help for the details.
I guess that is a "better suggestion", but only if you are using xxcopy.

The application/utility you have linked to is way more comprehensive and flexible
