identifying a service level objective for servicing the data access request, wherein the service level objective specifies a controlling metric and a non-controlling metric, the controlling metric comprising a minimum bandwidth to be met by a storage provider;

determining an operational performance of each of the plurality of storage providers that currently store the client data;

identifying a portion of the plurality of storage providers that meet the controlling metric based on their corresponding operational performance;

ranking, based on the non-controlling metric, only the portion of the plurality of storage providers that currently store the client data, wherein the non-controlling metric is at least based on a cost to access the client data;

identifying a first storage provider from the portion of the plurality of storage providers based on the ranking;

copying a first portion of data blocks corresponding to the client data from the first storage provider;

subsequent to copying the first portion of data blocks corresponding to the client data from the first storage provider, and prior to copying a second portion of data blocks corresponding to the client data, determining that the first storage provider has become inaccessible;

in response to the first storage provider becoming inaccessible, using the ranking of the portion of the plurality of storage providers to identify a second storage provider;

copying the second portion of data blocks corresponding to the client data from the second storage provider; and

reconstructing the client data using the first portion of data blocks and the second portion of data blocks to produce reconstructed client data; and
