Piping dd
Write to several devices at once with dd and tee:
$ dd if=INFILE | tee > (dd of=/dev/sdX) | dd of=/dev/sdY
dd over the network with netcat and bzip compression (not encrypted),
serverside...
$ nc -l 9000 | bzip2 -d | dd bs=1M of=OUTFILE
...and clientside:
$ dd bs=1M if=INFILE | bzip2 -c | nc SERVER 9000
Writing data to an ssh server, using xz transport compression:
$ dd if=INFILE bs= 1M | xz |\
ssh user@host "xz -d | dd of=OUTFILE bs=1M"
Reading data from an ssh server, again with xz transport compression:
$ ssh user@host "dd if=INFILE bs=1M | xz" |\
xz -d | dd of=OUTFILE bs=1M
