Abstract
One embodiment is related to a method for creating a redundancy data chunk for data protection with a chain topology, comprising: transmitting a data chunk of a first frontend zone of a data storage system to a second frontend zone of the data storage system; creating a redundancy data chunk at the second frontend zone of the data storage system based on the data chunk of the first frontend zone and a data chunk of the second frontend zone; passing the redundancy data chunk onto one or more subsequent frontend zones of the data storage system from the second frontend zone, wherein at each subsequent frontend zone the redundancy data chunk is updated based on the received redundancy data chunk and a data chunk of the respective subsequent frontend zone, and wherein the redundancy data chunk is passed through each subsequent frontend zone exactly once; and at a last subsequent frontend zone of the data storage system, forwarding the updated redundancy data chunk to a backend zone of the data storage system for final storage.
