Nowadays, the data de-duplication technology is no longer unfamiliar, and its value has been fully reflected in the backup domain, how to play the maximum value of duplicate data deletion technology is another problem that manufacturers need to think about.

As IT continues to effectively centralize services, the dual-hot standby mode of data centers is becoming more and more common, and the network traffic of internal data centers is becoming more and more important. However, as backup traffic increases, virtual machine migration, service-oriented architecture, or replication between storage arrays, the business volume generated between
