netcat is great for situations like this where security is not an issue:

# on destination machine, create listener on port 9999
nc -l 9999 > /path/to/outfile

# on source machine, send to destination:9999
nc destination_host_or_ip 9999 < /dev/sda
# or dd if=/dev/sda | nc destination_host_or_ip 9999

Note, if you are using dd from GNU coreutils, you can send SIGUSR1 to the process and it will emit progress to stderr. For BSD dd, use SIGINFO.

pv is even more helpful in reporting progress during the copy:

# on destination
nc -l 9999 | pv > /path/to/outfile

# on source
pv /dev/sda | nc destination_host_or_ip 9999
# or dd if=/dev/sda | pv | nc destination_host_or_ip 9999

clarify significance of argument "9999", minor wording changes, fix "localhost" to "destination_host_or_ip"
