Back-up copies of the application software or source code must be stored in a fire-rated container or stored separately (offsite).

Application developers and application administrators must take steps to ensure continuity of development effort and operations should a disaster strike. Steps include protecting back-up copies of development code and application software. Improper storage of the back-up copies can result in extended outages of the information system in the event of a fire or other situation that results in destruction of the back-up as well as the operating copy. To address this risk, copies of application software and application source code must be stored in a fire-rated container or separately (offsite) from the operational or development environments.
