Containers are generated including data containers storing segments of files, segment tree containers storing upper-level segments of segment trees representing the files, and cloud containers storing headers from the data and segment tree containers. A header for a data container includes fingerprints identifying the segments of files. A header for a segment tree container includes fingerprints identifying the upper-level segments. The containers are sent to cloud storage for storage as a cloud unit. The cloud unit is attached to a deduplicated storage appliance by storing at the appliance the segment tree and cloud containers, cloud configuration details, and an index. The cloud configuration details identify the cloud storage having the cloud unit. The index maps the fingerprints to the containers. When a cloud unit is to be detached, the segment tree and cloud containers, and index from the local storage are deleted, but the cloud configuration details are maintained.

The disclosure provides a system, computer readable medium, and computer-implemented method for managing data access. The method includes obtaining a data access request from a requestor for client data redundantly stored in at least two storage providers that are unknown to the requestor; identifying a service level objective for servicing the data access request; ranking the at least two storage providers based on the service level objective to identify one of the at least two storage providers to service the data access request; and providing the requestor with access to a copy of the client data using the one of the at least two storage providers.
