"reduce your kernel's size"
if I want to create a boot floppy, but it doesn't matter if I want to use a boot ISO instead.
== Disk Image for re-deploying a drive/computer ==
On a more recent "backup" effort, I needed to archive off the contents of a laptop to an external USB drive that was mounted on another system. The source system was a Windows XP machine, while the target machine was running Linux. The tools I used to make the backup were <code>dd</code><ref>http://en.wikipedia.org/wiki/Dd_(Unix)</ref> and a LiveCD of the [http://linuxmint.com/ Linux Mint] distribution. By inserting the Linux Mint Live CD, and rebooting the laptop, I would have access to a bash shell that I could then run the dd tool from. Not only that, but I could use the Secure Shell to pipe the command over the network to the target machine's mounted external 1TB drive. Note that in my case, I used a private key (identity file) to authenticate my ssh session.
<source lang="bash">
sudo dd if=/dev/sda2 | ssh -i /home/mint/id_rsa-greg-notebook greg@192.168.1.11 "dd of=/media/disk-a/backups/sheila-laptop/acer.image.2"
</source>
== Performance ==
In most backup scenarios, the first backup is the one that takes the most time.
