What does shadow file processing involve?

Shadow file processing refers to the practice of creating duplicates of files at concurrent processing sites to ensure that data is available and recoverable in the event of a failure or disaster. This approach enhances data resilience and allows for continuous operations across multiple systems or locations. By maintaining these duplicates, organizations can ensure that they have a backup in place that can be utilized for failover, thus minimizing downtime and data loss.

This method is particularly valuable in environments where real-time data access and processing are critical, as it allows for seamless transitions in the event of system failures. Additionally, having shadow files can facilitate parallel processing and improve load balancing among servers.

The other options do not accurately define shadow file processing. For instance, while archival data storage is important for long-term data retention, it doesn't involve concurrent processing. Similarly, while encrypting data files enhances security, it does not pertain directly to shadow file processing, which focuses on the duplication of files. The use of AI for data recovery is not related to the concept of shadow file processing either, as it involves different technologies and methodologies.
