Systems and methods for brokering storage services are disclosed. In one embodiment, the brokering system is configured to receive, from a client device, a request indicating a desired configuration for storing target data in at least one of the plurality of cloud storage services. The system can determine a first selection comprising at least one storage service from the plurality of cloud storage services based on the request, provision storage in the plurality of cloud storage services based on the determined first selection and provide, to the client device, a temporary manifest indicating the provisioned storage, wherein the temporary manifest comprises access data that enables the client device to access the provisioned storage in the cloud storage services. The system can then store the temporary manifest and determine whether the client device completed storing the target data on the provisioned storage based on a presence of the temporary manifest.
