Copy via tar pipe while preserving file permissions (run this command as root!)

tar -C /oldirectory -cvpf - . | tar -C /newdirector -xvf -
It's the same like 'cp -p' if available. It's faster over networks than scp. If you have to copy gigs of data you could also use netcat and the tar -z option in conjunction -- on the receiving end do: # nc -l 7000 | tar -xzvpf - ...and on the sending end do: # tar -czf - * | nc otherhost 7000

What Others Think

It's not always faster because the encryption of ssh/scp is not always the bottleneck depending on your CPU. Sometimes tar is apparently faster because it is actually streaming the files, so there is a sort of buffering going on, whereas with scp there is not.
