I'm more "tar" adept !
Here is the tar command :
# cd /src
# tar cf - . | ( cd /dst ; tar tvpf - )
This is just a try that display all file it will copy.
Now I copy for real
# tar cf - . | ( cd /dst ; tar xvpf - )
To copy through ssh on a remote machine
# tar cf - . | ssh root@host "( cd /dst ; tar xvpf - )"
bu scp is fine too
To avoid copy of /proc and other anoying file system you can use
--except ./proc --except ./sys .......
or better use -l to copy only /src and not other mounted filesystem
then you have to copy /boot and other data partition the same way.
cpio require you to use a filesysteme walker like find to generate the
list of file you wan to copy.
Something like :
# find . | cpio ???? | (cd /dst ; cpio ??? )
