Abstract
Described is a process for encrypting and compressing data for storage by computing systems. A data stream received by a computing system is separated into data chunks for storage on a storage device using a data layout format. Each data chunk is examined and if possible, compressed to produce a compressed data chunk. Whether or not the data chunk can be compressed, the data chunk is encrypted and stored on the storage device in addition to metadata that describes the data chunk. When reading the stored data chunk from the storage device, the metadata identifies the starting location of the stored data chunk and provides metadata information to the computing system for decryption and decompression processing.
