how to retain a fetched value from another workbook that get's moved and/or renamed

Hi gang

Still very new to learning excel, so this may be a very dumb question for most of you.

Im working with two work books, located over a network on different computers.

I'm currently using this formula in my "Book1" to pull data from "Book2"
=VLOOKUP(A1,[Book2]Sheet1!$A$1:$B$10,2,FALSE)
I could also use
=INDEX([Book2]Sheet1!$B$1:$B$11,MATCH(A1,[Book2]Sheet1!$A$1:$A$11,0)) Suggested by jeffreybrown when I was having an Issue.

But these link to the data. So if the data in Book2 changes, or the book itself gets moved or renamed/deleted. I'll lose the data in Book1.

Is there a "pull the current data and Keep it permanently" formula ?
Like a Ctrl+c then Ctrl+V but in a cell formula veriant

Cheers
