Re: Using DD To Back Up Debian

[Vojtech šmiro <vsmiro@seznam.cz>]

Hello,

if you want backup your system, use:

sudo dd if=/dev/sda1 of=file.iso

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

Best regards

Vojta.
