I always back up by data fastidiously, and unfortunately my primary backup drive was a casualty of the fire. In retrospect I wish I had one of these- not only is fireproof AND waterproof, it includes a data recovery service in the event of a disaster. There is also an SSD version, which is even less prone to failure and has faster read/write speeds to boot.

Redundant backups are important, and having one offsite is a great idea. Depending on your needs, there are many solutions: is great for storing small files on a remote server that you can access from anywhere, including your smartphone. is another great choice that store your entire Time Machine backup cache online.

Okay, maybe this is overkill but I really think that a fireproof laptop safe would have come in handy.
