A storage grid is provided. The storage grid includes a first cluster, a second cluster, and a third cluster. Each of the first cluster, the second cluster and the third cluster is configured to store an amount of data ranging from a portion of a copy of the data to a full copy of the data. The first cluster has a full copy of data written to the first cluster and at least a partial copy of data written to the second and third cluster. The second cluster has a full copy of data written to the second cluster, and at least a partial copy of the data written to the first and third cluster. The third cluster has a full copy of data written to the third cluster and at least a partial copy of the data written to the first and second cluster. A method of storing data is also provided.
