I think grub should keep the old MBR, with the date,
whenever it is changed.
Easy enough for the brighter user to:
dd if=/dev/XYZ bs=512 count=1 of=/path/to/MBR_copy
where XYZ might be hda for a common setup.
To be honest, I cannot remember the last time I wished I had an
MBR backup ;) So easy to make a new one.
Such a dd copy also contains the partition table as it was at the time.
If the partition table gets hosed, it is not trivial to rediscover the
partition boundaries in order to recreate the partitions.
If the primary partitions have changed since the copy was made, restoring
the backup could easily be a disaster. In terms of added security, nothing
beats *understanding* how the partition table and the boot sectors work.
On the other hand, if the partition table is not damaged, installing the
desired dos/lilo/grub/whatever boot sector is generally easy.
