For that reason I installed partclone (which CZ uses) on my ~bin folder and cloned my other partitions that way:
sudo ./bin/partclone.ext4 -c -s /dev/sda8 | gzip -c --fast>image.gz
I've just recently went back to using CZ usb flash drive. The reason is all the extra stuff it puts in the image folder. I hadn't used CZ for quite a while, and was impressed that you can now use the imaged file to restore another partition. Use to couldn't do that. Also the image verification that it now does is something I use to have to do myself...like I said, its been awhile since I last used CZ.
The problem with beginners using CZ, is its interface. Reminiscence of the DOS days and the unending text that flies by.
Even with that being said, its one of the best cloning tools around, if not THE best. True Image is faster on cloning, but I've had problems with it.
