Claim:
1. A method comprising: determining, by one or more processors, a need to replicate a portion of data into a remote failure zone within a data storage network; generating, by the one or more processors, a cost versus reliability improvement analysis, wherein the cost versus reliability improvement analysis includes an estimate of a mean time to failure (MTTF) for network switches, routers, protocol adapters, protocol ports, power supplies, mother-boards, CPUs, RAM, and storage media; and based, at least in part, on the cost versus reliability improvement analysis, sequentially creating, by the one or more processors, two or more replicas of the portion of data, wherein an earlier-created replica is removed after a successive replica is created and each successive replica is more remote from the portion of data than any earlier-created replica.
