Need to clone drive before I screw things up, help appreciated.

With the help of many members here I have a older ASUS 7745g laptop booting High Sierra properly. It still has the usual problems (sound, wifi, power management, 5M video etc.) but I'm excited to solve these driver details myself. BUT, really would like to know how to clone the drive first properly before screwing things up. I've seen the tuts on CCC and the Vault but most seem dated and wondering whats the latest best option with High Sierra?
