Abstract: The invention herein protects digital computer data from physical natural disasters such as fire and flood. While most methods of data backup to combat these threats rely on physical separation of the data and main computer system, this invention can be used inside the main physical computer and thus provide intervention-free data protection from environmental hazards. When implemented for use inside a computer, the invention adheres to industry standard specifications for size and electrical interfaces. This ensures maximum compatibility with the existing industry infrastructure; custom shapes, sizes, and interfaces would inherently be supported by the invention. Furthermore, the invention can replace the physical casing used by data storage devices. For example, the invention could replace the physical aluminum base casting of a desktop 3.5? hard disk drive. Alternatively, the invention can be used as a protective jacket to envelop a mobile 2.5? hard drive with a jacket dimensioned for 3.
