MBR Backup/Restore
Need to be root. I recommend using one of the "live" CDs like Knoppix or Mepis
and mounting a floppy for the 'filename.dd' destination.

Debian Live

Backup MBR to a File
dd if=/dev/hda bs=512 count=1 of=filename.dd

Restore MBR from a File
dd if=filename.dd of=/dev/hda

Backup MBR to Another Host
dd if=/dev/hda bs=512 count=1 | ssh user@host "cat - > 20040516-backup-mbr.dd"

Restore MBR from Another Host
ssh user@host "cat 20040516-backup-mbr.dd" | dd of=/dev/hda
