The recommended way to use Knoppix is the flash disk installation. With it you can install new packages or delete others you never need. Sometimes you want a backup tool to feel free for experiences with your installation.
I wrote a little script to create backups inclusive comment-files or to restore elder backups.

Very nice, Werner.
In my estimation, there is a great bonus here:
kn-backup.sh is also an elegant lesson in bash scripting.
