Abstract
A multi-stream restore method for reducing restore time of file data to service an external read request for file data stored by a data deduplication system employs a per-file read-ahead cache that is populated by multiple parallel internal read-ahead streams. The number of parallel read-ahead streams is dynamically variable based upon processing conditions and a set of heuristically pre-determined criteria that characterize the file data including a data access pattern that is sequential and a processing load that is below a predetermined threshold. Processing conditions are periodically monitored and adjustments to the multi-stream data access are made to optimize performance.
