I want to read file system of one ESP and write it to other ESP to copy all files once.

Probably esptool and read_flash is good for this task, but how to know where SPIFS starts and ends?
If this position is different for every chip, how to copy new file system image in a right place correctly?

Maybe spiffsimg can help: https://nodemcu.readthedocs.io/en/master/en/spiffs/
