Maintaining a duplicate copy of irreplaceable backup media is an effective strategy for mitigating the risk of loss during transit. Having a duplicate copy means that if the primary media is lost or damaged while being transported, there is still an accessible version of the data available. This redundancy decreases the likelihood of permanent data loss and ensures that crucial information can still be retrieved from the duplicate, thus safeguarding the organization against potential disruptions caused by data loss.

This strategy is particularly important when dealing with irreplaceable data, as the potential impacts of losing such information can be significant. Diverse scenarios could occur during transit—ranging from physical damage to the media, theft, or misplacement. By creating and storing duplicate copies, organizations can confidently manage the risks associated with data transport, as they have a backup readily available.

While other options like encryption, maintaining a chain of custody, and ensuring personnel are bonded offer additional layers of security and accountability, they do not directly address the risk of data loss specifically during transit like the duplication strategy does. For instance, encryption safeguards the data's confidentiality but does not provide a solution in the event that the media itself is lost or damaged. Similarly, chain of custody and bonding personnel ensure that the process is secure but do not mitigate the
