Why would your family have much trouble accessing the data on your system? Assuming you've stored the passwords someplace they can get to (and that assumes the disks are encrypted), even if they're tech-illiterate, they can just hire someone who knows how to work with Linux servers to retrieve the data (assuming that's what you're using). It won't be free of course, but unless you've devised some entirely custom OS and filesystem to store your family photos, it really shouldn't be that hard. Of course, you should probably write up some instructions so they don't need to hire an expert, but in the worst case where you get hit by a bus before you write them, it should be possible to get to that data. The real problem is if you're using encrypted filesystems, and you didn't bother to write the root password anywhere.
