The present disclosure describes systems and methods for aggregation and management of cloud storage among a plurality of providers. In a first aspect, the invention is directed to file distribution and management across multiple cloud services via a storage manager. The storage manager may aggregate third-party cloud storage provider accounts into a single cloud storage space and load balance files among the third party-accounts as necessary. In one implementation, the storage manager may act as an intermediary, and files may be transferred by the client to the storage manager, which may select and forward the files to a third-party storage provider. File retrieval may be performed similarly, with the client requesting a file from the intermediary storage manager, which may retrieve the file from the corresponding third-party storage provider and forward the file to the client device.
