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 small files in a prefetch queue such that a combined size of the small files meets or exceeds a size of the prefetch queue as defined by a prefetch horizon. A queue processor issues a read request for the first file in the queue, scans the prefetch queue to find a read request for a file at the prefetch horizon, and prefetches the file at the prefetch horizon. The prefetch queue essentially constitutes a hint from the client that a read I/O is imminent for purposes of filling the read-ahead cache and preventing a need to issue a blocking I/O operation.
