Abstract
Embodiments of small file restore process in deduplication file system wherein restoration requires issuing a read request within an I/O request to the file system. The process places the files in a prefetch queue such that a combined size of the files meets or exceeds a size of the prefetch queue as defined by a prefetch horizon. A file handler disassociates prefetch streams from read streams. The handler prefetches the read operations and stores them in memory. The stream corresponding to a read will only open as the read requests hit the queue processor. As a result, the stream usage is very low, since the I/O, worker threads and the read streams are disassociated from each other.
