Abstract
Improving extent-based read performance using pre-fetches by utilizing synthesized sequential extent files in a deduplication storage system. Extent information is obtained for changes between two generations (e.g., Generation 0 and Generation 1) of backup files. In a client-server system, the client will instruct the filesystem to create a new synthesized file corresponding to the extents. Upon receiving this request, a filesystem server will create the new synthesized file. The new synthesized file can be read sequentially to leverage the benefits of prefetching. The extents can be patched into a target file that may be stored on different storage using the extent information.
