In a tissue bank a disaster is double, because you can lose both the physical vials and the records that identify them. On the physical side we make sure tank monitoring, alarms, and redundant power keep specimens safe through outages and weather events. On the digital side we maintain immutable, offsite, regularly tested backups of every donor and inventory record so a ransomware attack cannot leave you with unidentifiable vials. We build and rehearse a disaster-recovery plan tuned to the scenarios that actually threaten a cryobank. That way inventory, eligibility records, and client orders can be restored quickly and completely.
