I often use rsync -a for remote systems or cp -a for local systems. I've also used dd. You can have dd output to stdout, pipe it to ssh and have ssh output to dd on the other end. You can also connect to a SAN device on the source and dd from the local block device to the SAN device. Lots of ways to do it ;) Cheers, C.J.
