As long as you know one hdd in a fireproof safe isn't a good backup.

The disk will break if the safe isn't waterproof.
The disk will break when the safe falls as the building crumples
The disk will break when the safe gets too hot as the fire rating is for
paper and it costs a lot more for one that will keep a disk safe.
It doesn't stop some scrote pinching your computer and the safe.
The disk will fail while copying the backup just as the main disk fails.
You copy any data errors caused by software to the backup and lose the data.

Do you want anymore reasons why its not a good idea?
