26 I did this the other day for an experiment. I used a spare partition,
27 and of course the partition concerned was unmounted:
28
29 dd if=/dev/sda4 of=backup.iso
30
31 then I did:
32
33 dd if=backup.iso of=/dev/sda3
34
35 I also have done a complete backup using tar to save some space.
36
37 tar cvfj backup.tar.bz2 /dev/sda4
38
39 when I decompress, I imagine I will mount the partition say /dev/sda3
40 and do the following
41
42 tar xvvf backup.tar.bz2
43
44 (This might be not accurate, but I hope it gives you a fair idea of
45 where to start)
