On a web server with a 3GB /dev/sda:-
dd if=/dev/sda | gzip | nc my_workbox 3333
At my workbox with a 1TB /dev/sda:-
nc -l 3333 | dd of=/dev/sda *instead* of:-
nc -l 3333 | dd of=bak_sda.img.gzip
first hint of idiocy was when I did a df -h to see how the transfer was
going, and got a screenful of gibberish... :-(
Not fun - cost me several hours to recover.
On the plus side I learnt a lot about testdisk, fsck, and ext4 journals :-)
Cheers
