Hi
One other thought is that one should have a way to
transfer the raw data from what ever media you have.
This allows one to have redundent information stored
on the same media. If you depend on normal file systems,
you run the risk of the file system not allowing you
to access the data simply because a small part is
damaged. I think most have been using normal file tools
that are not dealing with things in this sense. Most
of these types of systems have a weak link problem.
