A data storage device is provided, comprising a control module a first storage module a second storage module a third storage module and a buffer. The first storage stores a plurality of data sets. The control module receives requests for operations to be carried out on the plurality of data sets in the first storage module, executes the received requests and copies the plurality of data sets in the first storage module to the second storage module at a predetermined time. The control module further adds the received requests for operations to the buffer and persists the buffer to the third storage module by a synchronization means. The data storage device initializes the plurality of data sets in the first storage module from the second storage module and carries out operations corresponding to the requests from the third storage module in a recovery scenario.
