I also don't really understand what you intend to do. If you'd just like
to backup some (or all) files from your partition you can just copy them
to wherever you like. It doesn't matter if these are 'data files,
'system files' or qemu images.
(There are some funny OSs that distinguish between these types in order
to make it more difficult to clone an installation, but that's not the
case for linux)
You might consider keeping the file properties and/or to compress files,
in case you'd like to save disk space.
dd is capable of copying your disk / partition bit for bit. Read 'man
dd'. However, with current disk sizes this approach will probably be
highly inefficient as all the empty space is copied as well. For most
backup scenarios rsync or other backup tools are miles better. They are
also much more flexible (in case your replacement disk has different
specifications from the then dead one).
HTH, take care, YMMV,
