A recovery strategy should be developed for every information technology system in operation in an organization. This includes the servers, desktops, laptops, wireless devices, data and any device being used for connectivity. Priorities for IT recovery should reflect the priorities for the recovery of business functions. This means that systems that support critical functions need to be addressed first. IT systems required to support time-sensitive business functions and processes should also be identified as high priority and a plan should be developed.
Information technology systems require hardware, software, data and connectivity. Without one component of the “system,” the system may not run. Therefore, recovery strategies should be developed to anticipate the loss of one or more of the following system components:
- Computer room environment (secure computer room with climate control, conditioned and backup power supply, etc.)
- Hardware (networks, servers, desktop and laptop computers, wireless devices and peripherals)
- Connectivity to a service provider (fiber, cable, wireless, etc.)
- Software applications (electronic data interchange, electronic mail, enterprise resource management, office productivity, etc.)
- Data and restoration
Some business applications cannot tolerate any downtime. They utilize cloud based solutions to ensure they can access the data they need. This is a more reliable method because of the use of multiple data centers capable of handling all data processing needs, which run in parallel with data mirrored or synchronized between the centers. Not only does this move the data off-site but provides redundant copies.
It is impossible to avoid all disasters, but with the right preparation and a plan in place the disasters that do strike will be easier to handle. A good plan also provides some peace of mind when considering past disasters and the future of the organization.
