Re: Using DD To Back Up Debian



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.

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.
