How To Safe New knoppix-data.img

I just wonder why you insist on using Knoppix on 4G sticks nowadays. Just asking for problems, IMHO. Also, the CD version isn't very good for daily use, it is stripped down almost as far as it gets, and you may run into all sorts of problems when you try to upgrade/install missing programs. Starting with the DVD version on a 8G stick would have saved you all those problems in the first place.

It is also most helpful to keep track, approximately, of the disk use. With a 4G stick, and 600-800MB for the KNOPPIX image, you can't have a persistent image much larger than ca 3G. IMHO, it is also good practice to leave some space free on /mnt-system.

You just add what you need.

-Daily user of CD-Size Knoppix Live USB.
(Also, sometimes use some 2 Gb SDs, because I got 'em, but prefer 8 -16 Gbs)

OK - "just add what you need" on a 2GB SD - just updating the pakage lists, upgrading a few packages and adding some programs may fill up the maximum possible persistent store. For example, on my (DVD) system, /var/lib/apt is 142MB, and /var/lib/dpkg is 133MB. CD versions will be smaller, but it is very hard to tell the exact space requirements of a series of maintenance/upgrade/new-install steps. And avoiding updating/upgrading altogether is not advisable either.
Therefore, I pointed out what might give problems:

and you may run into all sorts of problems when you try to upgrade/install missing programs.

The context here is not what may work for someone, in particular knowledgeable users, but what kind of advice we give to new users who have run into problems already.
