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. A prefetch queue processor creates an intent to read the file, rather than opening the file upon receiving the request. During this step, the application passes the file handle of the file, and the destination handle where the data must be read into. As the queue is processed, the prefetch for the request (handle/offset/length) is passed to the file server. The filesystem processes the request to equivalently 'open' the file, and bring the data into memory. As the read request for the same file reaches the filesystem the file data is read from memory for writing to the destination handle.
