Abstract
Methods and systems for backing up data to a target device are described. According to some embodiments, the method receives a first set of data packets for backup, where the first set of data packets includes a multiplicity of data chunks. The method further captures footprints of the first set of data packets in a cache disk array. In response to receiving an acknowledgement from the cache disk array indicating the footprints have been captured, the method further initiates a write operation to write each data chunk of the first set of data packets to the target device. In response to receiving an acknowledgement indicating the data chunk is successfully written, the method further flushes the respective footprint of the data chunk from the cache disk array.
