Abstract: Systems and methods are disclosed for accessing data on a storage system. An apparatus, such as a data storage device or a computing device, may include a memory configured to store data. The apparatus is configured to determine an importance level for a file to be stored in the storage system. The data storage system includes one or more private storage clouds and one or more public storage clouds. The apparatus is also configured to generate a set of recovery data chunks based on the file and the importance level. The apparatus is further configured to store the set of recovery data chunks in the set of public storage clouds. The apparatus is further configured to store at least a portion of the file in the private storage cloud.

Abstract: Systems and methods are disclosed for accessing data on a storage system. An apparatus, such as a data storage device or a computing device, may include a memory configured to store data. The apparatus is configured to receive a request for a file stored in a storage system. The storage system includes a private storage cloud and a set of public storage clouds. The apparatus is also configured to determine whether the file is retrievable from the set of public storage clouds. If the file is retrievable from the set of public storage clouds the apparatus may determine whether access to the set of public storage clouds is faster than access to the private storage cloud and may retrieve the file from one or more of the private storage cloud and the set of public storage clouds.
