Are they located on the same hard drive? Only then would hard links
work. Just asking to be on the safe side.

Depends what you want to achieve. Doing that, both server trees would
point to the same data in the files. Thus, if you change the contents of
a file in one tree, its twin in the other tree would change also. If
that's what you want, cp -al would be fine. New files created in either
tree would have separate data, though.

I'm not sure what you want to achieve in the end. Why you want to have
those real copies for example. Could you please elaborate on your final

I find it more convenient to have separate vaults for different sources.
It keeps them clearly arranged and I can address them separately or move
one of them to another medium easily.
