Hi all,
I am trying to create a simple disaster recovery solution for a server, but before I started I wanted to check the theory.
The server uses a set of 2 SCSI disks (36GB each) mirrored using hardware RAID-1. There are two partitions, the system C and data D.
If I boot the system using a gentoo cd, load the correct scsi module can I just
cat /dev/sda1 > /dev/backup
where /dev/backup is a third disc of 36GB?
I don't think cat would get you the results you're looking for. Aslo, sda1 will only get your the 1st partition, and not the MBR.
Try "dd if=/dev/sda of=/deb/backup bs=8192". the device /dev/backup has to be as large or larger than /dev/sda. You can adjust the bs parameter as you see fit to enhance performance.
