Definition updates folder location questions

Quick question's on definitions update here.

When Nod32 finishes updating, where is the updates located? (folders and what specific file please)

Can I manually backup those update to a file folder of my choice and manually apply those updates through copy/paste?

I ask this as sometimes I need to revert back / use a system image and I want to update the definitions without having the need to connect to the internet at that particular time.

Can that be possible?

 

I can partially answer your query:
The update: nup files are located at:
"The default location of update (.nup) files of your ESET security product is for Windows 7 or Vista:"

Perhaps they could be imaged or extracted from a rescue CD
