Based on my experience with 5.25 inch floppies, 3.5 inch floppies, 100 meg zip disks. Qic 40 tapes, CD-R's, and DVR's I suspect the eventual offsite location will be the nearest landfill.
In case of fire, I care about my dogs. The tote is water proof. It's reasonably strong and though I live in earthquake country I live in a one story structure. Six sigma's to the burglar who burgles old hard drives from a closeted tote. I've long since accepted my more moral failings in regard to best backup practices. YMMV.
