clone identical HDD and leave both bootable
Hi,
Just looking for some info on the steps to copy exactly the contents of a disk to another for use in the same system. I want to use this as a backup disk if the first one goes.
Both drives are identical 36.4gb scsi, I havent physically plugged the second one into the server yet (Compaq DL350 G2). There is only 1 drive in their at present so no raid to be considered.
The OS is SCO Open server 5.
I not new to Linux but I have only ever learned to do certain things like FTP at command line and I can ls and move around the filesystem fairly well
So my questions are:
1. When I plug in the new drive and boot will I see it in the OS or will I have to mount it?
2. Can I copy the first drive to the second using DD? (While booted into the OS?) and will both disks be bootable afterwards, i.e. can I remove my old drive and put my newly DD'd disk into the first slot in the cage and away I go?
Or should I go with a live CD and use something like Ghost?
Many thanks for any pointers.
Rds,
Owen.
