Export / Backup my shopify store

Hello,

I intend to change completely the content and the appearence of my shopify store, so i was wondering if there is a way that i can export my store ?

I tried exporting in CSV my products and downloaded the zip of my theme. That been said, is that enought to backup entirely a shopify store, is there more i can backup or is there a better method that i should know about ?

Your help is welcome !


Thank you.
