Abstract
The disclosed embodiments provide a system that distributes data for a distributed filesystem across multiple cloud storage systems. 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. Whenever each cloud controller receives new data from a client, it outputs an incremental metadata snapshot for the new data that is propagated to the other cloud controllers and an incremental data snapshot containing the new data that is sent to a cloud storage system. During operation, a backup cloud controller associated with the distributed filesystem is also configured to receive each (incremental) metadata snapshot, such that, upon determining the failure of a cloud controller, the backup cloud controller can immediately begin receiving data requests from clients associated with the failed cloud controller.
