Patent ID: 8812455

Claim:
A method for processing data comprising: receiving data, wherein the received data is deduped; analyzing the data, wherein the data that has been deduplicated is analyzed for organizing the data into a self-contained datastream; creating file headers, corresponding file metadata based on a hash generated by a backup application, and corresponding file blocks based on analyzing the data, wherein creating the corresponding file metadata includes generating an offset to indicate location of a data block; organizing, in a low-latency cache, the file headers, corresponding file metadata, and corresponding file blocks into the self-contained datastream, wherein the corresponding file blocks are organized into the self-contained datastream based on an order indicated by offset information included in the corresponding file metadata, wherein: the file headers indicate a start of a file in the self-contained datastream; the corresponding file metadata includes location information for the corresponding file blocks; and the corresponding file blocks are organized in an image section and includes file blocks necessary to recover the file; the corresponding file blocks are organized in sequential order to reduce a number of disk reads, wherein the corresponding file blocks include deduplicated blocks; storing the self-contained datastream in a storage device; reading the datastream in a first sequence; and writing data based on the read datastream in a second sequence.
