Since cp -a [*] is useful to replicate a disk, I think you are really
asking "I would like to know why some people seem to prefer tar or cpio
to replicate a disk".

Well, I don't know the answer, but in either case, you have often to be
careful to avoid infinite recursive copying:

cd /
mount /dev/somedisk /mnt
cp -a * /mnt

See the mess? ( /mnt/mnt/mnt/... )


[*] -a does already include -R, see cp --help.
