Need help for Power Automate Copy file after it is updated to another sharepoint

I'm sure it has been done before. Embarking on a new type of workflow. I have at least 10 different flows that pull attachments from emails and save them to a Sharepoint Folder and it works beautifully. The next thing i want to do is we have 4 shifts 7 days a week and 2 excel files they update 24/7. I want to keep an archive of these in another folder. How can i have Power Automate look for the changes and return a copied file in another Sharepoint location? Thanks in advance for your help and Happy Holidays!
