"SD Card Copier" program that's in Raspbian, something like that to do easy backups in kalipi?

So I was able to get the raspi-config loaded in my kalipi but now im looking for an easy backup solution.

I already have a physical card duplicator that i use, but im looking for a dead simple bootable on board solution like in raspbian.

the "SD Card Copier" program that's in Raspbian, something like that to do easy backups in kalipi?

TO BE CLEAR something that takes the running system and copies it to a mounted sd card.

any advice? and thank you!!
