g4u is a REALLY nice front end to dd basically, but works very well and is
reasonably fast.
If you want fast,
dump | restore
as it will only copy data and ignore empty blocks. You then just need to
install the MBR which is easy to do via sysinstall if you are not
comfortable disklabel
e.g.
cd /;dump -C 20 -0f - / | (cd /mnt/root-disk; restore -rf - )
cd /;dump -C 20 -0f - /usr | (cd /mnt/usr-disk; restore -rf - )
and so on.
