If you go to prison, you can lose whatever media you have as well. I wouldn't rely on a single cloud storage provider, but mirror on multiple ones, and mirror on one or more local device as well, at least for the most important data. I wouldn't use physical media as primary backup copies today: long-term durability, and availability & support of matching peripherals are uncertain, and they don't make proper backups with redundancy easier, nor their verifiability.

For the kids, I'd rather make physical photo albums.
