Hello, if you want backup your system, use: sudo dd if=/dev/sda1 of=file.isoIf you have broken system and you want to restore it from your backup, use this:
sudo dd if=file.iso of=/dev/sda1it restores only your one partition. If you want restore all disk, you must write sda without number. That is same for backup.

Hi All, Now that I have Debian going on the Asus 701, I want to make a backup of the 4GB internal drive, and I booted up to Vinux on a USB drive to do a DD of /dev/sda. This Vinux is Ubuntu 11.04. So in the terminal I did: sudo dd if=/dev/sda of=/dev/sdb1/filename.iso And it gave me the DD error that the file name is not a directory. Can someone enlighten me to what I left out? Thanks.
