What factor can increase the cost when processing petabytes of data?

The cost associated with disaster recovery can significantly increase the overall expense when processing petabytes of data. Disaster recovery involves strategies and technologies that ensure data can be restored or maintained in the event of a failure, loss, or disaster. When dealing with large volumes of data like petabytes, the systems required for backup, storage, and restoration can be complex and expensive.

As organizations implement robust disaster recovery plans, they may incur additional costs related to backup solutions, offsite storage, replication services, and the infrastructure necessary to support these processes. This can include both hardware (like additional servers and storage systems) and software (like backup solutions and orchestration tools). Moreover, the need for redundancy to ensure reliability in disaster recovery can further drive up costs, making it a significant factor in budgeting for big data operations.

Understanding this context is essential for planning and managing big data initiatives effectively, as disaster recovery solutions must be scalable and efficient to handle the vast amounts of data typically involved while also being cost-effective.
