I have some basic doubts regarding imaging Linux Operating System (OS).
I have a complete back-up of my root partition and boot partition. Back-up is done using DD Utility. Below are the command i followed for back-up
dd if=/dev/sda1 bs=1k conv=sync,noerror | gzip > /tmp/boot_backup.gz (boot partition of 1 GB in size).
dd if=/dev/sda2 bs=1k conv=sync,noerror | gzip > /tmp/root_backup.gz (root partition of 20GB in size)....
