I have 2 80GB drives in my Dell Poweredge SC1430 webserver, set up as RAID, with Ubuntu 8.04LTS installed. Everything is running properly. I want to clone what the system sees as sda1 onto a drive that I have connected via a usb external enclosure.It is also an 80GB drive.
I have read and printed the instructions on "How to clone your bootable Ubuntu install to another drive" posted at http://www.arsgeek.com/2008/01/22/ho...another-drive/
My questions are about the dd command. ‘dd if=/dev/sda1 of=/dev/sdb1 conv=noerror,sync’. The machine I am cloning is a production web server. 1)Is there any danger in running the dd command while leaving the web server active? 2)Do I need to format the output drive before running the dd command?
