Redundancy
Duplicating critical components so a failure doesn't cause an outage or data loss.
Redundancy is the practice of duplicating critical components (servers, storage, network paths, power supplies) so that the failure of any one does not cause an outage or loss of data.
Redundancy is the building block of high availability and a key part of protecting the availability of ePHI. Examples include RAID storage, clustered databases, and multiple power feeds within a data center.
