Following some notes around netcat here and here.

Some extra commands to backup a disk over the network :

-listen on port 9000 and dump the raw file
nc -v -l -p 9000 > dump.img
(restore with nc -v -l -p 9000 < dump.img)

-same but compressed with lz4 via stdin
nc -v -l -p 9000 | lz4.exe -1 stdin -f dump.lz4
(restore with lz4 -l -c dump.lz4 | nc -v -l -p 9000
and not with nc -v -l -p 9000 -e « lz4.exe -c dump.lz4 »)

-the same but with 7zip
nc -v -l -p 9000 | 7z a dump.7z -si
(restore with 7z e dump.7z -so | nc -v -l -p 9000)

-the same but with bzip2
nc -v -l -p 9000 | bzip2 -z > dump.gz
(restore with bzip2 -cd < dump.gz | nc -v -l -p 9000)
