Re: how to create an image of your debian computer hard drive for cloning



I was wondering how I could make a clone or image of my computer hard disk
that contains debian OS. I want to do this in order to make an exact copy to
another clean pc with no os at all. What complete free software can I use
for this ? Is there a manual some where on the net about this ?
thanks

dd (man dd) doesn't work for you ? Or are you looking for something else ?


dd will work as long as you have boot media to access compatible hardware to perform the reverse dd cloning operation.

Boot from CD media and get to a shell prompt and have hard drive hda with your linux system on it and an operational tape drive linked to /dev/tape. Then you can create a clone via:
dd bs=512 if=/dev/hda of=/dev/tape

Then replace hda with another drive and restore the clone via:
dd bs=512 if=/dev/tape of=/dev/hda

To work with varying drive sizes and types, a commercial product like BackupEdge makes the process simpler.
