When designing a business continuity plan for an airline reservation system, which data transfer method is most appropriate for backup at an offsite location?

• A. Shadow file processing
• B. Electronic vaulting
• C. Hard-disk mirroring
• D. Hot-site provisioning

Answer: (A)

When designing a business continuity plan for an airline reservation system, the most appropriate data transfer method for backup at an offsite location is electronic vaulting. This method involves the automated transfer of data to a secure offsite storage location, ensuring that critical information is backed up regularly and can be quickly restored in the event of a failure. Electronic vaulting is designed specifically to protect data integrity and availability, which is crucial for an airline reservation system that requires real-time access to data for booking and customer management. It minimizes the risk of data loss while allowing for efficient recovery processes, which is vital for maintaining service continuity during disruptions. Other methods, while useful in specific contexts, may not provide the same level of remote data protection. Shadow file processing, for instance, creates copies of data files for use in backup scenarios but does not necessarily involve transferring these files to an offsite location. Hard-disk mirroring maintains a real-time copy of data on another disk but is typically limited to local environments and does not address the need for offsite backup. Hot-site provisioning involves setting up a fully operational backup facility that can take over operations but can be more resource-intensive and may not focus on the efficiency and automation that electronic vaulting offers for data backup.
