First of all, you DON'T want to DD the discs. At the very least, it's
a bad idea (IMHO). You DO want to mount the discs both on the same
system, and TAR or CPIO will work. Just be careful to specify the
command so it doesn't TAR the disc you're mounting (copying the disc
to itself). This isn't an issue if you just create a tar, but it is
if you...
You don't have to create the TAR file on the disc. Something like
"tar cf - /mnt ; ( cd /mnt2 ; tar xf - )" will pass one TAR to the
other and read and write at the same. Quite quick, especially if
you don't have the disc space free to create the tar file.
I prefer to use CPIO though. If you're copying your root disc, you'll
use something like (be sure to list all mount-points that you want
saved):
find / -xdev / /usr /var <other mountpoints> -depth -print | cpio -pdma /mnt
where "/mnt" is where the new disc is mounted...
