A simple way could be to use dd. Although you should have identical
drives for that to work reliably. Takes a long time too.
dd if=/dev/sda of=/mnt/nfs/someshare/sda.out
If the box breaks:
Replace disk
Boot with rescue disk
Bring up network
Mount nfs share
dd if=/mnt/nfs/someshare/sda.out of=/dev/sda
I wouldn't do that in production but it saved my butt before when a
drive started exhibiting errors and tar, etc. would crap out.
