Various embodiments for storing a logical object are provided. In one such embodiment, by way of example only, incoming data is divided corresponding to a logical data object into a plurality of independent streams, associating each data chunk of a plurality of obtained data chunks with a corresponding stream among the plurality of independent streams. At least one of the obtained data chunks and derivatives thereof is sequentially accommodated in accordance with an order the obtained chunks are received, while keeping the association with the corresponding streams. A global index is generated as a single meta-data stream accommodated in the logical data object and comprising information common to the plurality of independent streams and related to mapping between data in the logical data object and the obtained data chunks.
