I have a server (A) which has a 9 GB SCSI boot disk. I would like to backup this disk in such a manner, that I can easily put the entire content on another disk (upon failure) of the disk. This needs as I understand boot loader, mbr information copied too. I'd guess dd could do this. But I cannot be completely sure that the 2 disks are geometrically equal (there both 9 GB SCSI but different vendors). What procedure would you suggest for doing this? Thanks, Arie
