How do I backup my Office 2013 files?

[SDwriter]

I want to delete my recent 30-day-trial Office 365 install, which included Office 2016. I want to blow all that away but ensure that I still have my original Office SW (2013), as if 365 never happened.



FWIW, I downloaded and activated the 365 trial version last Tuesday, 9/26. I'm worried that 365 may have made changes to my 2013 and that removing 365 might break something with regard to 2013. This thread contains some background info:

So anyway. As a precaution I'd like to backup my Office 2013, which I dearly want to keep and use in the future. How do I do this. FYI, I have an external drive with 528 GB of free space for this purpose.
