Didn't find it via a forum search.
So, the only thing I have to do, is copying the file /var/local/cc.db to a safe place. If needed, I may restore it to another Kindle with the same fw version and content of the documents folder at the point of time I've saved the mentioned database file? (IOW: make a full backup of /mnt/us/ and additionally save /var/local/cc.db?) No other files from e.g. /var/local/* needed?
