Handling VDR data in case of an incident

The current performance specification for VDR's only requires that the data is stored for a minimum of 12 hours before being overwritten. Since many existing VDR's simply meet the required 12 hours, if no action is taken to preserve the recorded VDR data within 12 hours of the start of an incident, the data will be lost or overwritten, thereby negating the purpose of having a VDR installed.
