The purpose of storage-based replication methods is to duplicate stored or archived data in real time via a storage network in order to achieve additional redundancy. This helps to avoid data losses. The automated replication of unencrypted data, however, entails risks both in an organisation’s own network and when using public network providers. This way, unauthorised access to replication traffic is possible—for example, by means of FC analysers (FC replication) or sniffers (IP replication).
