This hasn't been addressed yet. After restoring the partition images from 
tape (presumably using a rescue CD), how does one make the system bootable?

BTW, I just saw an article on tape backup and how the media are still 
incredibly cheaper than disks (and far cheaper than SSD), but the drives 
are extremely expensive (like $3k) so prohibitive for single-server 
installations like the home user.
