To reduce the potential for future disasters, vital engineering terms to discuss when planning future sensitive projects include:
Fault tolerance: The property that enables a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components.
Redundancy: The inclusion of extra components that are not strictly necessary to functioning, in case of failure in other components.
Rollback: The process of restoring a database or program to a previously defined state, typically to recover from an error.
