You would, however, normally do this with dd. dd if=/dev/hda of=/dev/hdb bs=512 I also used this to image my firewall/router '/' partition coz it is quite small and also uses a small % of the hdd: (under 650M) $ dd if=/dev/hda2 bs=512 | gzip > hda2.gz Then of course to get it back: $ zcat hda2.gz | dd of=/dev/hda2 bs=512 Of course ensuring that the unused blocks are zerod makes gzip work very well.
