Howto | DD over SSH

Posted in: technology. Tagged: linux, howto, dd, ssh, cli

Wow, can’t believe my last post was 4 months ago, well a quick tip to get me back into the blogging frame of mind. If you wish to take a drive image copy over the network, then apparently you do not have to have an nfs share available. Instead you can use ssh as follows:

$ dd if=/dev/sda bs=1M | ssh root@blah "cat > /root/disk.img"

Haven’t tried it yet, but it sounds incredible. The bs=1M is essential or the copy will take forever.
