Nobody likes disasters, yet they happen to IT systems everyday. The first key component to a DR (Disaster Recovery) plan is to have a Data/System Backup solution in place. One that runs automatically, and self-checks and reports its results to a responsible party everyday. In addition, every business should have a DR plan that knows how to handle an IT system failure. For instance, to protect you in a power-failure situation, we recommend redundancy with your power supply systems. We also recommend redundant hard drive systems, as those fail from time to time.
Redundancy keeps you working when certain components fail. A Disaster Recovery plan considers the key areas that can potentially fail and implements a plan to execute if things do fail. It also helps identify weaknesses in IT systems that, when rectified, will decrease downtime risks, or help improve recovery times if and when a failure occurs.
