Disaster recovery is the process of restoring data, in this case, Noah data, following an event so severe that the physical record (paper or electronic) is destroyed. As with data backup, a policy must be written and implemented. Backups should be verified by performing a data restore. This restore should be to a different computer. Once the data is restored, it should be compared to the master data. Additionally, a plan should be implemented to allow patient records to be accessed in the event of a power failure. Possible solutions for this may include an uninterruptible power supply or having a battery-powered laptop computer that can access the backup data files. Longer battery life can be achieved on laptop computers by using power management software or additional external batteries.
Note on uninterruptible power supplies (UPS):
While a UPS can prevent a sudden loss of computer power, and thereby possible data loss, it is important to realize that generally, a UPS will only provide power for a matter of minutes. Their intended purpose is to allow for data to be saved and for the system to be properly shut down rather than to provide power for general operation.
