    Hi

    I hope to find the right "gurus" here for my question.

    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
