Abstract
The disclosed embodiments provide a system that archives data for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers cache and ensure data consistency for the stored data. During operation, a cloud controller receives a request from a client for a data block of a file stored in the distributed filesystem. Upon determining that the requested data block is not currently cached in the cloud controller, the cloud controller sends a peer cache request for the requested data block to a peer cloud controller in the distributed filesystem.
