The present disclosure describes systems and methods for aggregation and management of cloud storage to leverage processing provided by a cloud provider with aggregation of cloud storage services. Files may be pipelined to the processing provider and then resynchronized to an alternate storage service, with processing or metadata retained. In one implementation, files may be provided for processing, retrieved, and then separately provided for storage. In another implementation, files may be simultaneously provided for processing and storage at different cloud storage providers. After processing, the metadata of the file may be retrieved, and the file deleted from storage of the processing provider. The metadata may be synchronized with the stored file, or may be retained in metadata storage and retrieved by the client device during synchronization or file retrieval operations.
