Abstract

A mirrored storage system for applications is provided, which enables and supports the variation and dynamic adaptation of the Recovery Point Objectives (RPO) based on policies. Furthermore, methods are provided for running such a mirrored storage system. Said mirrored storage system comprises a first storage system and at least one further storage system, wherein said first and said further storage system are connected via at least one mirror link. An application accesses said mirrored storage system via a network. Therewith, the data to be stored as response to a write command of said application can be mirrored according to a configurable time-varying RPO requirement of the application transmitting the corresponding write command.
