dd Across The Internet With ssh and xz
23 Mar 2012
Here’s how you can back up an entire hard disk across the internet
xz to save as much bandwidth as possible, also
pv for progress):
$ ssh -p 2222 firstname.lastname@example.org 'dd if=/dev/xvda1 | xz -c' | pv > sonzonaroot.img.xz
To view your files on the other end:
$ xz -d sonzonaroot.img.xz # mkdir /mnt/disk # mount -o loop sonzonaroot.img /mnt/disk
You can always not
xz the image up if you happen to be limited by
CPU or RAM, rather than bandwidth.
