An online business dictionary (http://www.businessdictionary.com/definition/fault-resilient.html) presents fault-resilient as an economical alternative to fault-tolerant quote: "Economical alternative to fault-tolerant systems, fault-resilient systems duplicate only a few critical components instead of duplicating all (the entire system)".
