You can get “hardened” external drives that are fire and water proof. I think LaCie makes one.
I should have added - I just got a 2 TB portable external HD that’s a bit bigger than a pack of cigarettes. I use a regular external drive for my periodic backups but I plan to do monthly backups on the small form factor drive and keep it in the gun safe.
“You can get ‘hardened; external drives that are fire and water proof. I think LaCie makes one.”
That’s an option for sure. Two things:
1. The expense is much greater. Just a brief search shows that a 3TB costs 400+.
2. Is anything really fire proof and or water proof?
