How can organizations protect against data loss in the event of a disaster? The paper emphasizes on the migration from centralized mainframe computers to distributed client/server systems that has created a concern on data security and discusses the importance of developing an effective disaster recovery plan to mitigate the risk of a loss. Data Security is needed. This paper suggests a possible solution. If a disaster occurs to the organization that destroys a server or the entire network, a company may not be able to recover from the loss. Developing an effective disaster recovery plan will help an organization protect them from data loss. Implementing a robust disaster recovery plan is vital for ensuring business continuity and minimizing the impact of unforeseen events. The paper provides a practical guide for organizations seeking to strengthen their data security.
