integrity of linux copy of a git repo

If I make a recursive linux copy, "cp -rfp", of a git repo working tree is the resulting copy interchangeable with the original?

e.g. /orig-wk-tree was created via git-clone with the file:/// url and therefore is a "full copy" cp -rfp /orig-wk-tree /orig-wk-tree-copy (do some stuff that breaks /orig-wk-tree) rm -rf /orig-wk-tree mv /orig-wk-tree-copy /orig-wk-tree

Have I truly recovered the full integrity of the original, or have I unwittingly introduced some sort of corruption?
