"Call me paranoid, but my Windows Home Server does nightly backups to a
software-RAIDed disk array, Mozy automatically backs up my photos to the
cloud, and I rotate a full Ghost backup of my PC to an off-site safe deposit
box. No relatives needed. That should provide coverage against disk
failure, theft, fire, and probably even a thermonuclear strike since the
Mozy data center is somewhere in Utah."
