Original and backup do not match

I've found a few files in a SuperDuper-generated backup that do not match the original. I haven't found an easy way to automate the checking of this (there's a lot of data), so I'm not sure how widespread across this problem is along the backup, but it certainly exists. I'm extremely concerned by this, as there are no errors in SuperDuper's log, and the Smart Copy completes successfully. The backup target is an encrypted, password-protected disk image on an external FW drive). There follows some Terminal output demonstrating this mismatch. I'd welcome any input. While I realise I can delete and regenerate the disk image, I'm reluctant to do so without establishing just what's gone wrong here.

Here's some examples of files which do not match:

otis:mike$ ls -al .aspell.conflrwxr-xr-x 1 mike mike 38 6 Nov 17:37 .aspell.conf -> Library/Preferences/cocoAspell/en.conf
otis:mike$ ls -al /Volumes/iBook\ Users\ Backup/Users/mike/.aspell.conf
lrwxr-xr-x 1 mike mike 38 29 Dec 21:29 /Volumes/iBook Users Backup/Users/mike/.aspell.conf -> Library/Preferences/cocoAspell/en.conf

(Note modification times differ. Not sure if this is a problem.)

otis:mike$ head .aspell.conf
# conf (string)
# main configuration file
# default: aspell.conf

# conf-dir (string)
# location of main configuration file
# default: <prefix:etc> = /usr/local/etc

# data-dir (string)
# location of language data files
otis:mike$ head /Volumes/iBook\ Users\ Backup/Users/mike/.aspell.conf
otis:mike$ [NO OUTPUT -- backup is a binary file!]
otis:mike$ diff .aspell.conf /Volumes/iBook\ Users\ Backup/Users/mike/.aspell.conf
Binary files .aspell.conf and /Volumes/iBook Users Backup/Users/mike/.aspell.conf differ


The backup of this directory of MP3s also does not match: files sizes an modification times match, but the content of all files (except, strangely, Track 6) differ, as shown by diff. Quicktime cannot open the files on the backup.

otis:mike$ ls -al /Users/Shared/Music/The\ Be\ Good\ Tanyas/Hello\ Love/
