One obvious solution not already mentioned is to back up the bootloader
*in Linux* as a normal file, so the backup software can then just back
it up like any other file.  It's a simple enough workaround to the
deficiencies in your backup software.

dd if=dev/hda of=/boot/bootsector-backup bs=512 count=nnn

Stick it in as a daily cron job and you're done.  When it comes to
restoring, you can just dd it back and you're in business.

Very true.  The same software is likely also broken with GPT
partition tables, BSD partition tables etc., so it's not like it's
just grub at fault here!  For the most part, grub is a vast
improvement over LILO, and except for the odd corner cases which
grub doesn't cover, grub is a much better choice if you have the
