Making a backup is simple enough using tar, just remember to exclude the
pseudo directories such as dev, proc and sys. You can restore the image
using a live CD.... from memory (failing rapidly) the syntax would be
myImage.tgz --exclude=/sys --exclude=/proc --exclude=/dev --exclude=/var/run --exclude=/tmp --exclude=/var/tmp --exclude=/var/log /
or if you don't have space on the box ssh the file inline as follows....
tar -zcvpf - --exclude=/sys --exclude=/proc --exclude=/dev --exclude=/var/run --exclude=/tmp --exclude=/var/tmp |
ssh <ip address> "cat >myimage.tgz"
when restoring from a live CD (if necessary)
ssh <ip address> "cat myimage.tgz" | tar -zxvpf -
remember to mkdir the excluded directories above and to run grub to install
